Dear Colleagues,
It is with great pleasure that we present the accepted abstracts from the North American Brain Injury Society's Tenth Annual Conference on Brain Injury in this issue of the Journal of Head Trauma Rehabilitation. The conference will take place in Miami, Florida, on September 12-15, 2012.
We are delighted to have received a positive increase in abstract submissions from our previous event in 2011. The uniformly high quality of the research submitted and broad range of topics clearly reflect the advance now being made across the continuum of care in the field of brain injury.
For those of you unable to attend the NABIS meeting, we hope that the abstracts presented in the following pages will at least give you a feel for our annual event. In addition the nearly 100 oral and poster presentations abstracted in this issue, over 40 invited speakers will present the latest advances in the science, rehabilitation and treatment of traumatic brain injury. The preliminary conference program is posted on the NABIS website, http://www.nabis.org.
Our 2012 NABIS conference planning committee has developed an integrated educational program that promises to be of interest to researchers, clinicians, administrators, and other brain injury professionals. The conference will be a four-day, multi-track event that will cover a wide range of brain injury topics including medical best practices, rehabilitation, research, life-long living, pediatrics, and advocacy. Attendees are comprised of basic scientists, rehabilitation physicians, psychiatrists, psychologists, neuropsychologists, speech pathologists, occupational therapists, physical therapists, social workers, nurses, case managers, legal professionals, advocates and all others working in the field of brain injury.
New this year, NABIS is pleased to offer two important pre-conference sessions. The first session, entitled Perspectives in Pediatric Brain Injury, is an in-depth review of advances in pediatric brain injury and is presented jointly by NABIS and the KiDZ Neuroscience Center, Department of Neurosurgery & The Miami Project to Cure Paralysis University of Miami Miller School of Medicine. The second pre-conference session will address Neurotoxic Exposure with presentations from leading medical, neuropsychological, life care planning and legal experts. This workshop will discuss the types, assessment, treatment, rehabilitation, litigation and life care planning of neurotoxic exposure cases, which will be highlighted by current research and in-depth case reviews.
We hope that you will join us in Miami in September! We also encourage you to consider becoming a member of our multidisciplinary society by visiting http://www.nabis.org. Whether it is in the area of research or clinical care, NABIS stands behind the premise that advances in science and practices based on application of the scientific evidence will ultimately provide the best outcomes for those with brain injuries and the community as a whole.

The Value of CARF Accreditation for Brain Injury Specialty Programs
Christine MacDonell
CARF International, Tucson, AZ, USA
Introduction/Rationale
Accreditation is a tool that can be used by persons served, families/support systems, providers, and other stakeholders to identify a quality program. For over 20 years Commission on Accreditation of Rehabilitation (CARF) International has partnered with a variety of stakeholders to develop and refine standards for brain injury programs. With quality services for persons served as the context, an international standards advisory committee convened earlier this year to refine and update standards. Following an extensive field review that is open to the public, the new standards for brain injury specialty programs (BISPs) will be published by CARF in January 2013.
Method/Approach
CARF's standards for brain injury specialty programs (BISPs) apply to inpatient, outpatient, home and community-based, residential, and vocational programs that focus on the unique needs of persons with acquired brain injury (ABI). Services address minimizing the impact of impairments and secondary complications; reducing activity limitations; maximizing participation, including wellness, quality of life, and inclusion in the community; decreasing environmental barriers; and promoting self-advocacy. Organizations seeking accreditation for a BISP also meet CARF's ASPIRE to Excellence(R) standards which address an organization's business practices including assessing the environment, setting strategy, stakeholder input; implementing the plan, reviewing results, and effecting change.
Results/Effects
Accreditation as a BISP ensures that an organization maintains a focus on the unique medical, physical, cognitive, communication, psychosocial, behavioral, vocational, educational, accessibility, and leisure/recreational needs of persons with acquired brain injury and their families/support systems.
Conclusions/Limitations
Addressing both business and service delivery practices the standards offers a blueprint to organizations striving to provide value to their stakeholders, minimize risk, and continuously improve on how they do business.

Primary Study for the Therapeutic Dose and Time Window of PicrosideII in Treating Cerebral Ischemic Injury in Rats
Yunliang Guo
Qingdao University Medical College, Qingdao, Shandong, China
Introduction/Rationale
This paper aims to explore the optimal therapeutic dose and time window of picrosede II for treating cerebral ischemic injury in rats according to the orthogonal test.
Method/Approach
The middle cerebral artery occlusion (MCAO) models were established by inserting, intraluminally, a thread into the middle cerebral artery (MCA) from the left external carotid artery (ECA). The successful rat models were randomly divided into sixteen groups according to the orthogonal layout of [L16(45)] and treated by injecting picroside II intraperitoneally with a different dose at different times. The neurological behavioral function was evaluated by Bederson's test and the cerebral infarction volume was measured by tetrazolium chloride (TTC) staining. The expressions of neuron specific enolase (NSE) and neuroglial mark-protein S-100 were determined by immunohistochemistry assay.
Results/Effects
The results indicated that the optimal compositions of the therapeutic dose and time window of picroside II in treating cerebral ischemic injury were ischemia 1.5h with 20mg/kg body weight, according to Bederson's test, 1.0h with 20mg/kg body weight according to cerebral infarction volume, and 1.5h with 20mg/kg body weight according to the expressions of NSE and S-100, respectively.
Conclusions/Limitations
Based on the principle of the minimization of the medication dose and the maximization of the therapeutic time window, the optimal composition of the therapeutic dose and time window of picroside II in treating cerebral ischemic injury should be injecting picroside II intraperitoneally with 20mg/kg body weight at ischemia 1.5h.

Hope and Resiliency: A Model for Goal Attainment with Brain Injury Survivors
Barbara Barton
Western Michigan University, Kalamazoo, MI, USA
Introduction/Rationale
Introduction: This workshop will share a new model of looking at hope and agency based upon the perspectives of survivors, and offer suggested protective and risk factors that influence resiliency in coping with brain injury.
Rationale
A survivor centered rehabilitation goal-setting process can be challenging for any treatment team, due to the cognitive challenges presented by a survivor's clinical profile. The model, based upon constructs from Positive Psychology, provides a values-driven ladder to help clinicians identify with the survivor the steps needed to attain a 'wished-for' future.
Method/Approach
Concepts of Hope were identified through an inductive content analysis of responses from support group interactions in a small sample of brain injury survivors in a long term, residential setting.
Weekly meetings occurred to pilot the researcher's model of Hope, based upon Positive Psychology constructs. The model contains the following concepts that linearly are identified to map out the survivor's future dreams and aspirations: 1) Values Identification, 2) Pathway Goals, 3) Agentic Thinking, 4) Intermediate Goals, 5) Target Goals, and 6) Challenge Goals and the concept of 'Flow.'
Results/Effects
Data was gathered by first asking the survivors: "What is important to you in your life?," "What is important to you right now?" "If you could have one dream come true, what would it be today?" Then one weekly goal was set by the researcher with each participant and scripted on a construction leaf tree leave placed in the individual's room to serve as a visual cue of the target goal and behavioral steps needed to achieve the weekly goal. Every week, the researcher started the group with the three questions to promote and identify consistency in responses.
Conclusions/Limitations
While this small sample cannot be generalized, the process and model deserve further research attention as a method for goal identification and fulfillment in long-term survivors of brain injury. The researcher noted a marked, although subjective, improved mood following the highly structured support group meetings. In a residential milieu, it is sometimes difficult to retain motivation and life satisfaction. This weekly focus on self-directed goals and individual responsibility appears to be a method to enhance the survivor's satisfaction with their life.

Parental Perspectives of Special Education Services for Children with Traumatic Brain Injury
Joseph Richert1,2
1Special Tree Rehabilitation System, Romulus, MI, USA, 2Madonna University, Livonia, MI, USA
Introduction/Rationale
Parents and guardians of children with traumatic brain injury (TBI) assume many roles and responsibilities post injury. One critical role is to advocate for their child's needs in school. Return to school post TBI can be a challenging process for multiple stakeholders. Because of their injury, children may now be eligible for special education and related services and entitled to equal rights under education policy. For parents and others unfamiliar with the special education system, navigating through the processes can be extremely complicated.
Method/Approach
The authors were able to identify the challenges that parents and guardians encounter in the areas of parental involvement, communication, knowledge comprehension and efficiency. This was an Institutional Review Board (IRB) approved study which surveyed over 100 parents and guardians of children with traumatic brain injuries to determine critical challenges and needs they encounter in the educational system. Using an electronic survey format, the instrument was categorized into four areas: parental involvement, communication, knowledge comprehension and efficiency. This was a 28 question instrument which participants rated on a 5 point Likert scale.
Results/Effects
107 individuals responded to the survey. Some majority demographics: Female (81.3%, n = 87) [spacing diaeresis]Caucasian (60.7%, n = 65) [spacing diaeresis]Age 40-49 (43.9%, n = 47) [spacing diaeresis]Married (64.5%, n = 69) [spacing diaeresis]Suburban School District (65.4%, n = 70) [spacing diaeresis]Age of Child, 14-17 (39.3%, n = 42) [spacing diaeresis]Severe TBI (55.6%, n = 52)
Overall, parents faced significant challenges with respects to their relationships with educational personnel. For example, in the area of communication, 44% Disagree and 33% Strongly Disagree that "I am able to address my concerns with my child's educational team immediately." and 40% Disagree and 33% Strongly Disagree that "Educational personnel discussed supports my child would continue to need after leaving school."
Conclusions/Limitations
Individuals surveyed were parents and/or guardians of a child currently participating in either a residential or outpatient neurorehabilitation program. In addition, they were either a parent and/or guardian of a child served through an individual educational program. This information describes the needs of family systems as they provide care and advocacy for their child post injury. This research provides insight into the challenges faced by family members of students with traumatic brain injuries when navigating through the educational system. It addresses process improvement strategies in the areas of "Assessment and Evaluation," "Service Coordination," and "Advocacy."

Introduction/Rationale
Widespread use of improvised explosive devices have resulted in a high number of combat-related polytrauma injuries, including Traumatic Brain Injuries (TBI). Research indicates a lack of innovative, holistic patient centered approaches designed to address complex needs of TBI veterans with multiple issues, from anxiety and depression to financial difficulty. In designing a model of care to optimize recovery and help veterans re-integrate into the community, we reviewed the components of comprehensive care for veterans diagnosed with TBI and polytrauma. We also interviewed TBI experts and conducted interviews with veterans and caregivers to assess needs and goals for treatment.
Method/Approach
PubMed, CHINAL, EMBRASE, NARIC, PsyINFO, Cochare Collaboration, National Guideline Clearinghouse and ProQuest databases were searched. All search results were combined and duplicate entries eliminated. Titles and abstracts were reviewed using pre-defined exclusion criteria. 107 articles were selected for full text review. Of 33 sources that met inclusion criteria, 2 were randomized controlled trials (RCTs), 6 quasi-experimental studies, 6 systematic reviews, 3 integrative reviews, 3 clinical practice guidelines, 10 non-experimental studies, 2 expert opinion papers, and 1 case study. Each article was graded using the Johns Hopkins Nursing Evidence-Based Practice Model Evidence Strength and Quality of Rating scales.
Results/Effects
Overall quality of research evidence was good. However, little evidence was identified with regard to comprehensive combat-related outpatient Polytrauma/TBI rehabilitation programs and interventions for TBI at the post-acute and chronic stages, especially when TBI co-existed with other conditions such as PTSD, depression, pain and/or substance use disorder (SUD). Results of this review confirmed a significant heterogeneity among rehabilitation interventions for combat-related TBI and a lack of interventions specific to treatment of TBI within the context of polytrauma.
Conclusions/Limitations
This review confirmed a wide variation in practices among rehabilitation interventions for combat-related TBI and polytrauma, especially for rural veterans who reside outside of a reasonable commuting distance for access to care, in addition to the impact on families and caregivers. Having received numerous recommendations for rehabilitation interventions, we designed an integrated model of care for management of TBI within the context of polytrauma. Our goal is to refine this model to meet multiple and often complex needs of veterans.

Introduction/Rationale
The traditional ideas considered aphasia was caused by damage in the cortical language center, but lesions in subcortical structures could also produce aphasia, which was a special type of aphasia called subcortical aphasia. A common phenomenon was subcortical aphasics recoveried faster and the prognosis was also better than cortical aphasics, however, some subcortical aphasics had no obvious improvement after language training. The objective of this study is to screen the factors that affect severity of language disorder in subcortex aphasia, to analyze the characteristics of subcortex aphasia, the therapeutic effect of language training and to study its rehabilitation mechanism.
Method/Approach
Ten moderate degree subcortex aphasics and twelve severe degree subcortex aphasics were evaluated by Chinese Rehabilitation Research Center Aphasia Examination (CRRCAE) and the Boston Diagnostic Aphasia examination before and after four weeks of language training. The factors that affected severity of subcortex aphasia and characteristics were analyzed before training, and rehabilitation mechanism was examined before and after training.
Results/Effects
Severity of subcortex aphasia was related to age and the complication of apraxia of speech. There was a relatively high level in listening comprehension, reading, repeating and reading aloud abilities. After language rehabilitation therapy, language ability improved at different levels. All kinds of language abilities improved significantly in moderate degree subcortex aphasics. Comprehension and verbal communication capabilities increased obviously, but written communication abilities rarely advanced in severe degree subcortex aphasics.
Conclusions/Limitations
Age and the complication of apraxia of speech may be the important factors that influenced severity of language disorder in subcortex aphasia. There were specific clinical feature in subcortex aphasia. Almost all language abilities can be improved by language rehabilitation therapy, but the therapeutic effect between moderate degree subcortex aphasics and severe degree subcortex aphasics was different.

No. 411 Hospital of CPLA, Shanghai, China
Introduction/Rationale
The purpose of this study was to observe the effect of high-pressure oxygen (HBO) on the blood-brain barrier and the expression of MMP-9mRNA after acute traumatic brain injury (TBI). The study also explored the effect of HBO treatments on acute brain injury mechanisms.
Method/Approach
Acute TBI was induced in Sprague-Dawley rats by the free fall method. At one hour after injury and 12 hours of HBO therapy (0.25MPa), samples of brain tissue were measured for water content at 24 hours after injury. Evans determination and the application of RT-PCR expression of MMP-9mRNA were observed.
Results/Effects
After 0.25MPa HBO treatment of acute TBI, comparison of brain water content with the untreated group decreased (P<0.01), the injured side and non-injured side of the hemisphere and hippocampus compared with EB and MMP-9mRNA untreated group decreased (P <0.01), 0.25MPa normoxicnitrogen group injury side and non-injured side of the hemisphere and no significant changes in the hippocampus EB (P> 0.05). 0.25MPa HBO treatment group and the hippocampal hemisphere damage and MMP-9mRNA high EB in non-injured side (P <0.05), brain water content level and EB was positively correlated (r = 0.523, P <0.05), and MMP-9mRNA positive correlation (r = 0.564, P <0.05).
Conclusions/Limitations
HBO treatment of acute traumatic brain injury can protect the blood-brain barrier, thereby reducing cerebral edema. One of the mechanisms is reduction of MMP-9 expression with HBO treatment.

AppReview Website Project for the Brain Injury Community
Michelle Wild1,2
1ID 4 the Web, Laguna Hills, CA, USA, 2Coastline Community College, Costa Mesa, CA, USA
Introduction/Rationale
Smart devices are rapidly growing in popularity as cognitive prosthetics; however, what's missing is a centralized database of app reviews relevant to the brain injury community. There are hundreds of thousands of apps available for smart devices. How does an individual with a cognitive disability sort through the vast array of apps? Current review sites are not unique to individuals living with cognitive challenges. Individuals may have their own lists of recommended apps that are shared with clients and/or other professionals; however, there is a growing need for a centralized database of critically reviewed apps for the brain injury community.
Method/Approach
The need for a centralized database of critically reviewed apps for the brain injury community was identified over a period of time during which I received many phone calls, from survivors and professionals alike, requesting recommendations for apps. The project described here provides the opportunity for both brain injury survivors and professionals to list apps that they are familiar with and to review apps listed in the database. Brain injury survivors and professionals within the VA, private rehabilitation centers, education, and other brain injury organizations were consulted as the project evolved. The outcome of this project is http://mccappreviews.com.
Results/Effects
http://Mccappreviews.com includes many specialized features to assist the brain injury community in finding appropriate apps. Features include moderated listings to assure apps are legitimate, moderated reviews to assure reviews are relevant, app categories relevant to the brain injury community, and unique review fields designed to gather information relevant to the brain injury community (e.g., "What cognitive skills do you think this app helps with?" and "How do you use this app in your everyday life?"). The site currently has over 100 apps listed. In addition, the site is listed as a referral on a number of sites, including http://Brainline.org.
Conclusions/Limitations
The site has evolved based on user feedback and suggestions since it was launched. One such upgrade involves users' ability to do a side-by-side comparison of a number of apps within a common category. Several side projects relate to the original project, including a monthly 30-minute app Webinar series related to top-rated apps from the site and AppBriefs, a series of brief app-specific instructional videos. The biggest challenge relates to informing the brain injury community of the site's existence. Future goals include partnering with those interested to enhance the site and make it a standard for the brain injury community.

Introduction/Rationale
Traumatic brain injury (TBI) is a complex and unique injury which encompasses a myriad of challenges for the survivor and relationships with family and friends. Sustaining a TBI results in familial strain due to the significant impact it has upon the role and function of the individual with TBI in the family and in the community. Caregivers of individuals with TBI face many challenges. Sequelae of TBI often include physical, emotional, psychological and psychosocial ramifications that are further complicated by limited access to educational materials, financial, and social resources and supports for both the caregiver and the individual with TBI.
Method/Approach
The Brain Injury Association of Florida, Inc. commissioned WellFlorida Council to conduct a needs assessment of caregivers of persons with TBI in the state of Florida. Focus groups were conducted to gain meaningful qualitative insights into the major caregiving issues among caregivers. Responses obtained during discussion theme areas manifested into the development of the questions for a TBI caregiver survey which was distributed to all caregivers whose loved ones participate in BIAF's TBI Resource Support Center. The purpose of the survey was to monitor the perception of critical support needs among caregivers and determine how these needs are being met.
Results/Effects
Focus group data indicates that the specific stage of caregiving, whether during the initial period of hospitalization, or the long-term survival process, is relevant and may predict caregiver needs. In the secondary module of the survey, respondents were asked to indicate the stage which they currently identify and were asked a set of questions with a comprehensive set of response options that apply to respondents who identify with any given stage. The 2011 TBI Caregiver Survey is a robust instrument designed to accurately assess the needs of caregivers in various stages of the caregiving process.
Conclusions/Limitations
The data suggests that in the context of challenging injuries and limited resources, caregivers often place the needs of the survivors, above their own needs. This impacts the physical, emotional, social, and psychological wellbeing of the caregiver.
These findings, while limited by the relatively small convenience sample of respondents, suggests that caregivers and their survivors would benefit from improvements to the caregiver support group infrastructure and campaigns to increase awareness about the support group resources available to caregivers within their communities. Results, insights and applications from this study will be presented.
Plans for future use of this survey will be discussed.

Introduction/Rationale
Traumatic brain injury (TBI) affects 700,000 females in the United States each year, making it a significant health care issue for which there are limited treatment options. One therapeutic strategy that has been investigated is environmental enrichment (EE). EE confers cognitive and motor recovery in female rats when provided continuously after TBI vs. standard (STD) housing. As a model of rehabilitation, continuous EE is not clinically relevant however, because TBI patients typically only receive 4-6 hours of rehabilitation per day. Whether abbreviated EE confers benefits similar to that of continuous EE in female rats is unknown.
Method/Approach
To investigate the potential efficacy of abbreviated EE after TBI, fully anesthetized female rats received a controlled cortical impact (2.8 mm tissue deformation at 4 m/s) or sham injury (i.e., no impact) and were randomly assigned to TBI + EE [4 hours], TBI + EE [6 hours], TBI + EE [continuous], or TBI + STD groups, and respective sham controls. Motor function (beam-balance/beam-walk and rotarod) was assessed on post-operative days 1-5 and every other day from 1-19, respectively. Spatial learning/memory (Morris water maze) was evaluated on days 14-19.
Results/Effects
The data showed that EE, regardless of dose, improved motor function compared to STD housing (p < 0.0001). Only continuous and 6 hour EE, however, enhanced cognitive function (p < 0.0001).
Conclusions/Limitations
These data demonstrate that abbreviated EE in female rats produces motor and cognitive benefits similar to continuous EE after TBI and thus abbreviated EE may be a pre-clinical model of rehabilitation. Future studies will further evaluate the potential benefits of abbreviated EE by combining it with various pharmacological therapies that may provide synergistic benefits.

Introduction/Rationale
The objectives were to determine 1) if poor affect recognition and empathy significantly explained community integration success for participants with traumatic brain injury (TBI); and 2) if reduced affect recognition, empathy and community integration after a TBI significantly accounted for the amount of relationship stress and support. Research suggests that people with TBI often lose the ability to recognize and empathize with others' emotions. Research also indicates that people with a TBI often have difficulty with community integration, and that the quality of their relationships is often compromised. Understanding how these variables are related can be useful for developing appropriate treatment.
Method/Approach
191 participants with moderate to severe TBI were tested for facial affect recognition (Diagnostic Assessment of Nonverbal Affect 2-Adult Faces). 158 family and friends of the participants with TBI reported on perceived Relationship Stress and Support (Life Stressors and Social Resources Inventory; LISRES); empathy (Empathic Concern, Perspective-taking; Interpersonal Reactivity Index) and Community Integration (Total, Home and Social Integration; CIQ) of the person with TBI. Participants were recruited from the USA, Canada and New Zealand. 70% of participants with TBI were male. On average, participants were 40 years old (range 21-65) and were 10 years post-injury (range: .5-42).
Results/Effects
Hierarchical regression revealed that affect recognition and empathy significantly accounted for 20% of total community integration (p<.001) and 22.5% of social integration variance (p<.001). Affect recognition, empathy and community integration significantly explained 31% of perceived relationship stress (p<.001), and 40% of perceived relationship support (p<.001).
Conclusions/Limitations
Affect recognition and empathy appear to play a significant role in community reintegration following TBI. Individuals with more empathy and better community integration were more likely to be involved in more supportive and less stressful relationships. It was a limitation that not every participant with a TBI had a family/friend to report on their behalf.

Operation TBI Freedom: Re-shaping the Transition of Service Members/Veterans with Traumatic Brain Injury
Alfredia Johnson
Bridget Fogelberg
Rocky Mountain Human Services, Denver, CO., USA
Introduction/Rationale
With the high numbers of service members returning to contiguous United States (CONUS), after multiple deployments, there is a need for communities to assist with the transition of these service members/veterans. Injured service members/veterans are continuing to struggle with issues of substance abuse, financial stability, employment, relationships, social skills, suicide, and a plethora of other problems. These men and women are having difficulty re-shaping their new purpose after leaving their military careers and the struggles they are facing can affect their families, workplaces, and, ultimately, the communities of which they are a part.
Method/Approach
Operation TBI Freedom, a privately-funded program of Rocky Mountain Human Services, is a community-based, non-profit program that uses military peer case management to provide these much-needed supports and services to transitioning service members in the state of Colorado with traumatic brain injury (TBI). The program pairs the service member/veteran with a Military Support Specialist,(former military personnel themselves) and Certified Brain Injury Specialists (CBIS), to provide peer resource support, linking the service member/veteran to their benefits and other services including homelessness prevention, cognitive strengthening, assistive technology, wrap around family services, and educational and employment support.
Results/Effects
As of May 2012, Operation TBI Freedom has had 143 graduates from the two year program. Military Support Specialists have assisted clients in the following ways: homeless prevention assistance = 21% of clients; employment support = 27% of clients; mental health issues, including suicidal ideation = 52%; substance abuse issues = 13%; marital issues = 41%; education = 51%. In surveys conducted at the time of program completion, 81% of clients expressed that they strongly agree/agree that their lives had improved due to the services received from Operation TBI Freedom.
Conclusions/Limitations
More brain injury programs and resources are needed throughout the United States. The ratio of graduates to total program participants is due in large part to the relocation of service members/veterans. More peer support groups are needed to assist with the issues of TBI and suicides. With more knowledge of these issues, communities will be better equipped to assist these service members/veterans with their transition. Rocky Mountain Human Services will be expanding into the surrounding 10 states in the future with the hope of continuing to generate awareness of the issues facing service members/veterans.

Enhancing the Adoption of Best Practices in Traumatic Brain Injury Rehabilitation
Marcia Scherer
Hanno Petras
Eileen Elias
University of Rochester Medical Center, Rochester, NY, USA
Introduction/Rationale
Research is needed on the effective assessment, assignment, and use of cognitive support technologies (CSTs) as TBI rehabilitation interventions to help individuals with traumatic brain injury (IWTBI) attain higher levels of cognitive functioning and community integration. While research shows that CSTs can improve cognitive functioning, there is a lack of evidence-based practices to guide rehabilitation professionals in ways to appropriately assess IWTBIs and assign CSTs so that they use them to support rehabilitation and everyday functioning. As a consequence, almost 90% of individuals with a cognitive impairment, including TBI, abandon use of these devices, thus limiting their rehabilitation potential.
Method/Approach
This presentation will identify the current, and needed, research to address the challenges in matching IWTBIs with appropriate CSTs that meet both their cognitive needs and their personal priorities. These findings emerged from a literature search that was conducted to: (1) identify the use of CSTs to compensate for cognitive impairments and their outcomes, and (2) derive correlates of CST use and nonuse among IWTBIs assessed for such a device.
Results/Effects
The presenters will discuss findings regarding: 1. how TBI-based rehabilitation providers currently use evidence-based tools to assess IWTBIs' readiness and match to CSTs; 2. how continued and appropriate use of CSTs by IWTBIs has led to improvements in functioning and enhanced community integration (e.g., participation in higher education, vocational training or employment); and 3. the gaps in necessary research-based results and needed actions to expand the knowledge base.
The presentation will increase awareness of the importance of expanding the evidence-base for CST readiness and use, as well as present a validated measure to assess CST readiness: Cognitive Support Technology Predisposition Assessment.
Conclusions/Limitations
The presentation will identify how findings obtained from the literature will enhance needed evidence-based research on CST use as an integral TBI rehabilitation treatment intervention. Areas of emphasis will include the importance of longitudinal analysis; IWTBI readiness for consistent and appropriate CST use; the importance of assessing CST readiness for use; and how the literature points out the importance of attaining medical insurance payer buy-in for CST use.

Introduction/Rationale
Right hemisphere strokes commonly give rise to a visuo-spatial neglect syndrome, a neurological condition considered to be a better predictor of functional dependency than the actual stroke severity [1, 2]. According to the interhemispheric rivalry hypothesis [3, 4], neglect could be caused by the overinhibition exerted by the left parietal cortex onto the injured right homologue regions via the inhibitory transcallosal projections. Several studies in small populations have piloted the use of repetitive transcranial magnetic stimulation (rTMS) in the intact hemisphere, in animal [5] and human [6-8]. Nonetheless, a randomized double blind controlled clinical trial of this approach is still lacking.
Method/Approach
The project "PHRC Regional NEGLECT" is a state-funded ongoing multicenter double blind clinical trial in human chronic stroke patients aimed at evaluating the efficacy and safety of 10 consecutive sessions of real vs. sham 1Hz frequency rTMS in the intact left posterior parietal regions to improve neglect derived from right stroke damage. Classical paper-and-pencil and computer based neglect tests, along with left parietal function assessment and a long list of motor performance, cognitive status and mood evaluation scales have been implemented not only during the 10 day rTMS regime, but also for up to 6 months post stimulation.
Results/Effects
The hypothesis is that patients submitted to real patterns of rTMS will show higher levels of neglect recovery than those receiving sham rTMS, and that these effects will be contingent to lesion severity and neglect impairment. Furthermore, it is predicted that visuo-spatial progress will trigger ameliorations in motor deficits following along.
Conclusions/Limitations
This paper will discuss alternative therapies, based on the use of the rTMS, that could be used to trigger restitution effects in cognitive, sensitive and motor areas affecting stroke patients. The choices taken and the problems encountered during the preparation of such an ambitious clinical project will be shared and discussed.

Hyperammonemia in Patients with Brain Injury
Radhika Bapineedu

Irene Ward
Kessler Institute for Rehabilitation, West Orange, NJ, USA
Introduction/Rationale
Abnormally high levels of ammonia (hyperammonemia) after brain injury may be due to anoxia, seizures, liver dysfunction, hepatotoxic medication, or muscle breakdown. As hyperammonemia can cause cognitive dysfunction and as it is a treatable condition, it is important to determine the frequency of this lab value in patients admitted to acute rehab with the diagnosis of brain injury as it may warrant routine screening in the future. The objectives of this study are to identify frequency of hyperammonemia in patients with brain injury and to identify potential factors associated with hyperammonemia in those patients with brain injury.
Method/Approach
A total of 133 medical charts met the inclusion criteria for this IRB approved retrospective pilot study. Patients with brain injury were dichotomized into two groups, those with hyperammonemia (>32 mcg/dl), or those with normal ammonia (<=32 mcg/dl), based on serum blood levels. Analysis included percentages to assess frequency of hyperammonemia in patients with brain injury, odds ratio to assess likelihood of having hyperammonemia and Pearson's chi square analysis to determine if the frequency of clinical and demographic factors was significantly greater in patients found to have hyperammonemia when compared to those with normal ammonia levels.
Results/Effects
Thirty, or 22.6% of the sample, were found to have hyperammonemia. Of those found to have hyperammonemia, the largest proportion of cases, 70%, were found to be in patients with traumatic brain injury (TBI). Furthermore, patients with TBI were 3.83 times more likely to have hyperammonemia than normal ammonia (p<.001). Whereas the highest proportion of the normal group, 48.5%, was found in those with non-TBI. Of the clinical and demographic factors tested, only one, elevated liver function test (LFT), was found to be significantly associated with hyperammonemia in brain injury patients, 76.7% (p<.01).
Conclusions/Limitations
This pilot study was the first step in determining the significance of routine ammonia testing in brain injury patients, otherwise, not commonly done upon admission. Results from this pilot study suggest that patients with TBI are more likely to have hyperammonemia. Interestingly, only one of the three liver-related factors tested appeared to be associated with hyperammonemia. Since hyperammonemia is known to cause impaired cognition, routine testing and treatment may help improve cognition in a population impaired due to their injury. Future research is warranted to identify the issues contributing to hyperammonemia in patients with brain injury.

Deborah Crawley
Jessica Giordano
Brain Injury Association of Washington, WA, USA
Introduction/Rationale
To review critical components of sustainability which need to be addressed as a priority for any service organization's long-term planning. The Brain Injury Association of Washington (BIAWA) will provide, in detail, its' collaborative approach involving private and public donors/agencies.
Method/Approach
The BIAWA provides direct support to individuals with brain injury, both pediatric and adult, and their families and caregivers throughout the state of Washington. These services include a toll free Resource Line, pediatric and adult in-person Resource Management, Clinical Case Management, Support Group support, and Support Activities. Over the past few years, BIAWA has incorporated best practices to reorganize its' infrastructure in a manner which has not only increased the value of its' services and the numbers served, but has also ensured long-term sustainability of service provision.
Results/Effects
The results of these efforts of the BIAWA includes increasing the geographic area covered by in-person services by 450% in 2011; hiring the first ever in-person Pediatric Resource Manager to cover King County in 2011; expanding Pediatric services statewide in 2012; fielding more than 6,000 calls per year to provide support, information & referrals; maintaining a database of more than 1,100 resources specifically vetted for those affected by brain injury; utilizing client-centered/goal driven practices to set clients up for success and providing support services, which are not available elsewhere, at no personal cost to individuals with brain injury, their families, and caregivers.
Conclusions/Limitations
The presentation will review the implementation of services provided by BIAWA; discuss ways other organizations can utilize policies and procedures to expand and improve upon services with existing funds; effectively assuring more comprehensive and widespread support to assist clients with social reintegration after injury in all areas of life, and be a successful non-profit business model.

Introduction/Rationale
Acute post-traumatic brain swelling (BS) is one of the pathological forms that needs emergency treatment following traumatic brain injury (TBI). There is controversy about the effects of craniotomy on acute post-traumatic BS. The aim of the present clinical study was to assess the efficacy of a unilateral decompressive craniectomy (DC) or unilateral routine temporoparietal craniectomy on patients with unilateral acute post-traumatic BS.
Method/Approach
Seventy-four patients of unilateral acute posttraumatic BS with midline shift of more than 5 mm were divided randomly into two groups: unilateral DC group (n = 37) and unilateral routine temporoparietal craniectomy group (control group, n = 37). The vital signs, the intracranial pressure (ICP), the Glasgow outcome scale (GOS), the mortality rate and the complications were prospectively analysed.
Results/Effects
The mean ICP values of patients in the unilateral DC group at hour 24, 48, 72 and 96 after injury were much lower than those of the control group, and the mortality rates at 1 month were 27% in the unilateral DC group and 57% in the control group (p = 0.010). Good neurological outcome (GOS Score of 4 to 5) rates 1 year after injury for the groups were 56.8% and 32.4%, respectively (p = 0.035). The incidences of delayed intracranial hematoma and subdural effusion were 21.6% and 10.8% versus 5.4% and 0, respectively (p = 0.041 and 0.040).
Conclusions/Limitations
Our data suggest that unilateral DC has superiority in lowering ICP, reducing the mortality rate and improving neurological outcomes over unilateral routine temporoparietal craniectomy. However, it increases the incidence of delayed intracranial hematomas and subdural effusion, some of which need secondary surgical intervention.

Early Decompressive Craniectomy for Traumatic Brain Injury May Lead to a Shorter Stay in Intensive Care: A Pilot Analysis at a Metropolitan Major Trauma Centre.
Andreas Demetriades
Nektarios Mazarkis
Clemens Pahl
Christos Tolias
Kings's College Hospital, London, UK
Introduction/Rationale
The effectiveness of decompressive craniectomy (DC) is yet to be proven. DC has the advantage of lowering intracranial pressure (ICP), but can have serious complications. The aim of this pilot study was to evaluate the outcome of patients undergoing DC for raised intractable ICP following head injury at King's College Hospital, a metropolitan major trauma centre in London, UK.
Method/Approach
From the cohort of patients admitted to intensive care following traumatic brain injury (TBI) the cases of 10 consecutive patients who underwent DC for raised intractable ICP were reviewed. All patients who required initial evacuation for intracranial haematomas were excluded, as well as those whose records were incomplete, or whose initial scans were not available.
Results/Effects
The ICP dropped from 34+/-2.8 preoperatively to 21.1+/-1.1mmHg postoperatively. Early DC (<24 hours) correlated significantly with a reduced length of stay in the Intensive Care Unit (ICU) (rpb = 0.72, p = 0.019). There was no correlation between the time of DC and Glasgow Outcome Scale (GOS). There was no correlation between the age of the patient and the timing of DC. There was no correlation between age and GOS (p>0.05). Lower values of ICP following DC were associated with higher GOS at an average of 20.5 months after the operation, however, this did not reach statistical significance (rpb = 0.65, p = 0.06). There was no correlation between Glasgow Coma Scale (GCS) prior to surgery and GOS post-operatively (p>0.05).
Conclusions/Limitations
While the results of the present pilot study are limited by the sample size, the reduced stay in ICU after early DC might have important clinical and financial implications. With the estimated cost of intensive care, at [pounds]1500-2000 per day, early DC could mean a saving of [pounds]12000-16000 per patient.

Project Victory - A Brief, Intensive, Residential Treatment Program for Mild Traumatic Brain Injury from Combat-Related Blast Exposure: A Description and Preliminary Data Analysis
Gary Seale
Kay Eaton
Sybil Yancy
Shawn Jaffray
Transitional Learning Center at Galveston, Galveston, TX, USA
Introduction/Rationale
An estimated 1.64 million United States (US) armed forces troops have served in combat theatres in Afghanistan (Operation Enduring Freedom) and/or Iraq (Operation Iraqi Freedom) since October, 2001. According to a recent RAND report (Invisible Wounds of War, 2008), approximately 19.5%, or about 320,000 troops sustained mild traumatic brain injury (mTBI), or multiple concussions during deployment. Post acute brain injury rehabilitation services for this population are lacking. Project Victory was developed to provide interdisciplinary, residential post acute rehabilitation to active duty and veteran service men and women who sustained mTBI due to blast exposure while serving in OEF/OIF theatres of combat.
Method/Approach
The Project Victory program encouraged the development of skills and compensatory strategies necessary for safe performance of advanced activities of daily living (ADL's), use of external aids for memory compensation, use of prolonged exposure techniques for treatment of post traumatic stress disorder (PTSD), motivational interviewing and stage change techniques for treatment of substance use/abuse, use of the Shut-I protocol for sleep disorders, and community exposure for treatment of anxiety in community settings. Participants received 5-6 hours of skilled therapy, Monday-Friday, delivered by licensed/certified staff. Program effectiveness and treatment outcomes were evaluated by participant satisfaction surveys and by objective outcome measures administered at admission and discharge.
Results/Effects
Sixty-two percent (62%) of participants demonstrated improvement in function as measured by the Mayo Portland Adaptability Inventory-4 (MPAI-4). The greatest improvement was noted in the Ability subscale which measured ADL's and cognition. All participants reporting substance use/abuse upon admission showed improvement as measured by the Alcohol Use Disorders Intentification Test (AUDIT). Only 15% of participants returned to abusive levels of alcohol consumption after discharge. Seventy-five percent (75%) of participants reported fewer depressive symptoms as measured by the Center for Epidemologic Depression (CESD) scale, and 64% reported an increase in life satisfaction as measured by the Satisfaction with Life Scale (SWLS).
Conclusions/Limitations
Brief, intensive, residential treatment using an integrated, multidisciplinary and evidenced-based approach may be an effective post acute rehabilitation model for mTBI due to combat-related blast exposure. While the preliminary analysis of Project Victory appears promising, a number of limitations exist including small sample size and non-random assignment of participants to treatment. A significant number of participants were lost during follow-up; and maintenance of outcomes after discharge from Project Victory is therefore not known. Treating mTBI and accompanying co-morbidities as chronic conditions will be discussed.

Tablets and Smartphones as Compensatory Memory Strategies.
Danny Ridley
Cynthia Bailey
Touchstone Neurorecovery Center, Conroe, TX, USA
Introduction/Rationale
The success rate of using traditional memory notebooks in rehab settings is inconsistent, and even worse post-discharge. There are many reasons including the bulkiness/awkwardness of the book, and the fact that they only work if you open them. Smartphones and tablets have the advantage of size, multiple input styles (talking, typing, writing), and they can be set to remind one of things even if not opened. In addition, because these tools are valued and have a "cool" factor, they are more likely to be used. And, one tool can address many problems and is more convenient to carry.
Method/Approach
Residents were chosen based on certain criteria established by speech and neuropsych, and were randomly assigned to a traditional, or electronic, group. They used their own smartphone/tablets if they had one, or were provided one to use during their stay. Residents were taught the basics of using a calendar, reminders, emails/text, GPS and organization/note-taking techniques, as well as rules of appropriate use.
The dependent variables were the number of sessions to train and the number of days until achievement of specific goals, (i.e., taking effective notes, finding an item in the memory book in a specified time, and completing a prospective memory task).
Results/Effects
Training on the paper and pencil tasks took longer than the tablets, partly due to the residents' familiarity with the devices and partly due to the intrinsic user-friendliness of current tablets and smartphones.
Preliminary findings indicated increased compliance with the use of the electronic tools, with resulting increased independence in following schedules and completing tasks.
Conclusions/Limitations
Use of electronic devices increases the face validity of the tool, and is more convenient for the residents. The cost of both the smartphone and/or the tablet is however, often a problem upon discharge, and few, if any, insurance companies cover this cost. Problems with sensation, motor planning, or visual deficits, may also be problematic with both electronic and traditional memory compensatory devices.

Using iPad Apps to Address Language Deficits in Patients with Aphasia
Anna Coburn
Cynthia Bailey
Touchstone Neurorecovery Center, Conroe TX, USA
Introduction/Rationale
Success in speech therapy often requires repetitive drills, which patients may find boring and difficult, and which often require a third party to either provide feedback, or assist in the drill (holding cards, holding a workbook, etc). Using apps which target reading, pronunciation, spelling, writing, formulating sentences, etc, may increase residents motivation, participation and independence.
Method/Approach
Residents were chosen based on those who needed repetitive drills in speech therapy. Use of apps on an iPad allowed the resident to receive automatic and consistent and immediate feedback from the program, and to keep track of scores so residents could see improvement. This approach was intrinsically rewarding, unlike paper and pencil tasks.
Results/Effects
Residents spent more time using the apps than paper and pencil, and reported they enjoyed it more. In addition, families engaged more as they found the apps more interesting than paper and pencil. The immediate feedback given after every response encouraged the residents, and most apps provided cues and hints when the wrong response was given. Results were kept on the pad, or sent to the therapist immediately.
Conclusions/Limitations
Use of electronic devices increases the face value of the tool, and is more convenient for the residents. The use of iPad apps, or any other computer program, is not however, meant to replace therapists. It is only meant to enhance the treatment program and to provide increased opportunity for the patient to learn and practice language skills in an intrinsically rewarding and structured manner.

Traumatic Brain Injury May Shed Light on the Nature of Cognitive Malfunction in the Elderly Who Have Experienced Previous Head Injuries During their Youth. Light and Electron Microscopic Studies of the Blood-Brain Barrier.
Albert Lossinsky1
Bonaventure Magrys2
1University of Medicine and Dentistry of New Jersey, Newark, NJ, USA, 2New York State Institute for Basic Research in Developmental Disabilities, Staten Island, NY, USA
Introduction/Rationale
Traumatic brain injury (TBI) is a consequence of blunt force trauma to the head. Older patients who have experienced single or multiple head traumas during their youth commonly express early onset dementia. The purpose of the study is to initiate exploration of a general hypothesis that the blood-brain barrier (BBB) fails as we age and that TBI will accelerate and exacerbate BBB failure with increased permeability and cognitive malfunction. The study was also intended to demonstrate that experimentally-induced TBI in young mice may exacerbate BBB failure in aged animals with an increased accumulation of perivascular amyloid protein deposits.
Method/Approach
Young C57Black mice were subjected to moderate controlled cortical impacts (CCI). At 1.5 hrs, 8 and 14 days post trauma, all animals were given a single intravenous injection of horseradish peroxidase (HRP) tracer that circulated for 30 minutes prior to transcardiac perfusion with buffered aldehydes. Brain slices from selected ipsilateral and contralateral hemispheres were incubated to detect the presence of HRP, then post fixed and embedded in plastic. Plastic brain slices from 3 aged dogs and 1 aged monkey without CCI were evaluated for BBB pathology. All brain tissues were examined by light and electron microscopy using a Hitachi 7500.
Results/Effects
Light microscopy demonstrated edema within the penumbra of the brain lesions spreading to the hippocampus CA2 and CA3 regions. Ultrastructurally, edema was observed within perivascular astrocytic processes representing a breach in the BBB. HRP leakage was observed in blood vessels distant from the surface of the brain lesions, in the hippocampus and ventral cortex. Blood vessels from brain regions showing edematous changes demonstrated increased endothelial vesiculocanalicular structures and microvilli protruding from their luminal surfaces. The vasculature of the aged dogs and monkey demonstrated thickening of some vessel walls and striking numbers of perivascular macrophages and pericytes loaded with fatty cellular debris.
Conclusions/Limitations
The data demonstrates that acute CCI produces immediate BBB alterations as demonstrated by edema formation, increased endothelial cell vesiculocanalicular structures containing HRP reaction product and increased endothelial cell microvilli. Increased BBB permeability secondary to a CCI may accelerate vascular thickening and deposits of Alzheimer's Disease-like amyloid beta and apolipoproteins during the aging process. The studies attempted to better understand changes in the BBB and neurons and question cognitive changes associated with elderly individuals who have experienced TBIs earlier in life. The studies are also relevant for assessments of concussion and comma, especially in casualties of automobile accidents, wars, and the athletes in the various sports arenas.

Introduction/Rationale
Timely diagnosis and management following traumatic brain injury (TBI) are crucial to improve patient outcomes. Computed tomography (CT) scan is an optimum tool for quick and accurate detection of an intracranial hemorrhage. While consensus exists regarding the value of initial head CT in TBI patients, guidelines on the use of repeat CT differ among institutions. A well performed systematic review and meta-analysis incorporating all available evidence on the topic does not exist.
Method/Approach
We conducted a broad search of Medline, Cochrane, and http://Clinicaltrials.gov and a hand search of relevant conference abstracts and references from selected publications for all completed studies reporting data on change in management following repeat CT. Two reviewers selected all studies and extracted data using a standardized extraction form. A proportional meta-analysis was conducted using random-effects model for outcome of any change in management following repeat CT. A subgroup analysis of mild TBI patients was performed. All outcomes are reported as proportions with 95% confidence intervals (CI).
Results/Effects
Of 6,982 identified references, 41 studies enrolling 10,501 patients met pre-determined inclusion criteria. The pooled proportion of any change in management following repeat CT from 13 prospective and 28 retrospective studies was 11.4% (95%CI 5.9-18.4) and 9.6% (95%CI 6.5-13.2) respectively.
The pooled proportion of any change in management following repeat CT for mild TBI patients as assessed in 5 prospective and 9 retrospective studies was 2.3% (95%CI 0.3-6.3) and 3.9% (95%CI 2.3-5.7) respectively. Heterogeneity among studies was significant for all outcomes.
Conclusions/Limitations
Results show that in the majority of TBI patients administration of repeat CT does not result in change in management. Additionally, the reporting of results in these studies is poor. The findings also highlight the need to standardize reporting of outcomes among TBI studies and the need for a well designed and reported study.

Electrophysiologic Evidence for the Effects of Acute Cerebral Concussion in a Collegiate Women's Soccer Player
Scott Livingston
University of Kentucky, Lexington, KY, USA
Introduction/Rationale
A 19 year-old women's soccer goalkeeper sustained an acute cerebral concussion following a blow to the head during an intercollegiate game. She did not demonstrate any loss of consciousness or post-traumatic amnesia, but complained of headache, balance problems, and poor concentration following the injury. Five days post-injury the athlete underwent neuropsychological testing using the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) protocol, post-concussion signs and symptoms (PCSS), and motor evoked potential (MEP) assessment. Transcranial magnetic stimulation (TMS) was applied over the primary motor cortex to elicit MEPs.
Method/Approach
The motor threshold, MEP response latency and amplitude, cortical silent period (CSP), and peripheral MEP latency were recorded from the contralateral tibialis anterior muscle using EMG recording. Both absolute and relative CSPs were determined. Central motor conduction time was calculated based on cortical and peripheral MEP latencies. ImPACT test scores were analyzed to determine verbal and visual memory composites, visual motor speed, reaction time, impulse control, and a cognitive efficiency index. PCSS were derived from the ImPACT test symptom inventory and reported as a total symptom score. All measures were serially assessed on days 10, 15, 30 and 45 post-injury.
Results/Effects
Initial total symptom score was 86 compared to 8 at baseline, and decreased to 23 by day 45. Visual motor speed demonstrated the most pronounced change from baseline (baseline = 38.2, day 5 = 46.53, day 45 = 50.08). Motor threshold decreased from 53% at baseline, to 25% on day 5, and remained below baseline (38%) on day 45. Absolute and relative CSP durations were prolonged at day 5 compared to baseline, and demonstrated a gradual decrease (or shortening) through day 30 but did not return to baseline values until post-injury day 45.
Conclusions/Limitations
The delayed CSP duration (both absolute and relative CSP) persisted up through day 30 post-injury, despite symptom resolution and improved neuropsychological test performance, and did not return to baseline values until 45 days following concussion. Because CSP is thought to represent GABA-mediated cortical inhibitory mechanisms, the prolonged CSP duration for up to 30-45 days post-injury provides evidence for persistent neuronal inhibition even in the presence of improving neurocognition and a decrease in total symptom scores.

"Transitions": a Program to Bridge the Gap between Rehab and Life
James Bogart
Cynthia Bailey
Touchstone Neurorecovery Center, Conroe, TX, USA
Introduction/Rationale
The concept of Transitions is to provide treatment in a group setting for those residents who will be returning to independent living in the community. It is a holistic approach which helps the individual address challenges they may expect once they return to their home, and cope with changes in their relationships, careers, and selves.
Method/Approach
Residents are chosen for this program, which is held for two hours a day twice a week based on cognitive and psychological criteria. The program is limited to six participants at a time to maximize group dynamics. If needed, more than one program can be run, but the same participants are always scheduled with each other. The approach is acknowledgement of the resident's value as a human and using a success oriented approach to achieve the best outcome obtainable. The peer component is valuable and essential.
Results/Effects
The Transitions program has been in existence for a couple of years and has had success. At this time randomized scientific trials have not been completed, but it is of note that many clients have not only rated the classes as valuable, but have made specific notations that it was instrumental in making them feel they could succeed, which is very important with this level of client.
Conclusions/Limitations
This program appears to increase the level of motivation and helps the resident "buy in" to the rehabilitation program. At this point in time, a way to objectively measure the impact of the program has not been developed. Also, the nature of the program requires a certain level of intellectual and emotional maturity. We are looking at ways to modify the program to work with less insightful residents.

Service Utilization in the Community: Development of Stratifications of Care
Jennifer Anderson
Christen Mason
Alan Weintraub
Aimee Voth Siebert
Denver Options dba Rocky Mountain Human Services, Denver, CO, USA
Introduction/Rationale
Rocky Mountain Human Services, the contractor for the State of Colorado TBI Trust Fund, has served 3,332 individuals across the State since 2006. Due to the growing demand for services and expectation to increase number served, we are evaluating the most cost-effective way to deliver care based upon level of need. Over the course of this year, we are collaborating with Craig Hospital to analyze patterns and variables within our intake process to more specifically predict level of care. This predictable stratification of care model includes but is not limited to an implementable system offering Comprehensive, Supportive, and I&R Referral Services.
Method/Approach
Monthly meetings were convened with medical professionals and researchers from Craig Hospital to offer guidance on how to structure the evaluation-intake process. It was agreed that of the 220 questions on the intake assessment that we could identify 10 key questions that were significantly linked to the level of care assigned. A qualitative query of the on-site care coordinators was completed to identify predictors of level of care. Data was evaluated from 350 individuals who entered the Trust Fund from 9/2011-12/2011. Intake assessments were analyzed using the Chi-square tests of independence (differences of p = .05 or lower).
Results/Effects
As predicted, results indicated six questions that identified or differentiated stratification of care. Questions pertained to the following themes: access to financial benefits, housing, emotional well-being, medical needs, social supports, and volunteerism.
Focus groups will be conducted within the next 60 days to have the clients complete the Mayo Portland Inventory in order to compare the stratified level of care to the RMHS intake assessment's level of care. The subject pool will be 60 individuals from the original pool of 350. Additionally, a predictive analysis of data elements will be conducted on the 60 individuals.
Conclusions/Limitations
Initial evaluation of RMHS assessment tool were consistent with predictive results and program evaluation over the past six years. Further research needs to be completed to validate the most effective tool to determine appropriate Stratification of Care for community based care coordination programs. The tool needs to be cost-effective, easy to administer and scored. Tool needs to be sensitive to services clients receive outside of the Trust Fund and funds allocated to them through the program. We anticipate validating a tool to determine Stratification of Care within the next twelve months.

Deep Water Horizon Blast Injury Survivors
Ralph Lilly
University of Texas Medical Center Houston, Houston, TX, USA
Introduction/Rationale
Case reports of six Deep Water Horizon Survivors are presented. Each sustained all of the components of Blast Injury. The components, primary, secondary, tertiary, and quaternary, were variable but severe in all instances. Rescue efforts, because of the circumstance, were variable, as was primary and secondary management. All of the survivors suffered complex neurobehavioral deficits, the major residual deficits to recovery being PTSD. Diagnostic methodology including imaging, psychiatric and neurolpsychologic assessment is reviewed. Team management and two year outcomes are reported.
Method/Approach
All of the survivors were seen on an outpatient basis at variable times following the explosion. The referrals were requested for the neurobehavioral complexities produced by the blast, resulting in the combination of Blast Overpressurization, Blunt Cranial Trauma, thermal burns, smoke inhalation, and exposure to life threatening circumstance and death. Management required detailed neuro and mental status exam, correlation of the diagnostic studies, and the establishment and monitoring of an ongoing interdisciplinary program. Photographic documentation of the explosion will be presented to support the enormity of such a trauma.
Results/Effects
The long term assessment of the neurobehavioral syndromes produced in survivors of a massive off-shore oil rig explosion is outlined. This experience provides a unique window supporting the currently accepted significance for a poly-organic evaluation for survivors of Blast Injuries. Special attention to the presence of PTSD as the most salient disabling feature in all the cases is discussed.
Conclusions/Limitations
The pathophysiologic features outlined in these cases associated with massive Blast Injury define the traumatic experience of blast injuries extending beyond the overpressurization factors of blast. While these case reports provide an avenue of prognostication, management planning, and the development of prophylactic guidelines, they more importantly reflect the need for active research on the parameters discussed.

Andrew Palumbo2
Patrick Morrissey2
1Brain Injury Services, Springfield, VA, USA, 2Outside the Lab, Great Falls, VA, USA
Introduction/Rationale
Long-term outcomes from brain injury are difficult to predict and more challenging to fully understand. We see athletes who have been concussed, soldiers coming back from war with brain injuries, even political figures who have sustained brain injuries through assault whom lived to tell their stories. Even though traumatic brain injuries now receive unprecedented attention in popular media, the common perception of recovery still tends to gloss over the longer-term struggles that many face. What can we do to help others really understand what they are going through and to encourage successful reintegration?
Method/Approach
This workshop will debut a new video designed to help laypersons understand the impairments and changes in abilities that occur following brain injury. The video guides viewers through primary functions of the brain as presented by personal testimonials from survivors of brain injury regarding daily challenges and successes they face. It is also narrated by active professionals in the field.
Results/Effects
Individuals who view this video gain a better understanding and perspective regarding what individuals with brain injury experience by seeing and feeling their brain injuries through their personal experiences. The professional narration assures clear scientific and clinical grounding, something that is often absent from such intimate examinations. The video has also been recognized for its potential to teach a number of professions, such as clinicians, caregivers, attorneys and policymakers.
Conclusions/Limitations
Many survivors of brain injury can appear to be completely uninjured in their day-to-day lives, but the fact remains that altered brains often result in persistent hidden challenges that can have adverse and dramatic daily effects. Just as advances in neurology have improved the survival rate of those who sustain a brain injury, increased awareness and understanding of these injuries by laypersons and professionals will help improved recovery and reintegration of brain injury survivors. By exploring the cases presented in this video and tying them back to today's understanding of the brain, this silent epidemic is given a new voice that can speak to people unfamiliar to brain injury.

Staying Connected Through Social Media: Connections for Compassionate Caring
James Conway
Teresa Flamini
Sharon Harton
Lauren Gower
ReMed Recovery Care, Paoli, PA, USA
Introduction/Rationale
The role of social media in re-establishing and maintaining social networks fosters reconnections with families and friends of individuals many years post injury. Many who prior to this opportunity faced social isolation and separation from loved ones. Social isolation and depression are among the most commonly reported problems after traumatic brain injury. Distance, transportation and other physical barriers often make getting out into the community difficult. Additionally, family fears and hesitation of social interaction due to perceived and/or historical behaviors may have previously acted as a barrier.
Method/Approach
Social networking opportunities like Skype, Facebook and email allow individuals to remain connected to family and friends as well as to form new relationships. The team working with individuals in a post acute brain injury setting built on social opportunities to keep connected with family members who lived a few hours away to across the country. The individuals with a TBI have significant expressive and receptive language difficulties or deficits which make traditional phone contact challenging. A progression from phone contact to email to Skype, Facebook and YouTube was facilitated by the team.
Results/Effects
The use of social networking has improved outcomes for both clients and families as personal and family barriers of poor self esteem, feelings of rejection and insecurity regarding relationships were reduced providing a portal for maintaining personal and family contact. Use of the types of interactive dialogue has enhanced relationships of clients, families, significant others and care providers."Seeing" their family member on Skype was a visual way for someone with a TBI to communicate when their disability affected speech, language and communication.
Conclusions/Limitations
There were several benefits to the types of social networking opportunities used which included easy access and low cost. A decrease in risk-taking behaviors, aggression and depressive statements was noted. Positive outcomes were seen in relationships with family members that previously appeared disconnected or unsure of how to interact with their loved one. Disabled individuals are faced with additional hazards with possibility of exposure to scam artists and required assistance to maintain safety in our ever-changing virtual social world. Some were limited to one or two types due to increased age or limited electronic access of family members. The potential benefits appear endless.

Emergency Preparedness and Ensuring the Safety of Persons with Disabilities
Cindy Daniel
Brain Injury Services, Springfield, VA, USA
Introduction/Rationale
The most lethal part of an emergency is the lack of preparedness in dealing with it people are caught off guard, becoming confused, frightened, and disoriented. These challenges are even more pronounced for those with disabilities. This became alarmingly apparent in 2004 with Hurricane Katrina, when thousands of evacuated people simply fell through the cracks. After critical analysis of what went wrong and under new legislation mandating precise procedures, we now have more refined means of guiding people through emergency situations. The efficacy of which can be seen in more recent disasters such as Hurricane Gustav in 2008.
Method/Approach
The major failings in dealing with Katrina were a lack of communication, education and resources for dealing with large-scale chaos. For example, emergency service providers were simply ill-prepared for handling the volume of shocked people. As the result of responsive education and protocols put in place to solve these problems, by the time Hurricane Gustav hit four years later, supplies were made accessible more quickly, emergency workers were prepared to guide citizens out more efficiently and the general attitude through the emergency was significantly more calm and collected due to what the community and agencies had learned.
Results/Effects
We can be better prepared for future emergencies by distilling the lessons learned over the last eight years into these four steps of prevention:
Why don't we prepare?
Understanding people with disabilities
Accommodating people with disabilities in an emergency
Preparing for an emergency
Conclusions/Limitations
It is possible for us all to have a clearer understanding of why we should prepare before an emergency hits and what to do when that happens. This also dramatically improves aid to people with disabilities, especially survivors of brain injury. The following questions can help us be better prepared:
Do you have a "go kit" ready?
Do you have an emergency plan, or know where to go if you are evacuated?
Hospitals and shelters
Is your facility fully accessible to people with disabilities in a disaster?
Service providers
Do you have the means of providing accessible transportation in an emergency?

Developing a Concussion Questionnaire for Parents and Student Athletes
William Frey1
Kellie Martin2
1Castleton State College, Castleton, VT, USA, 2Brain Injury Association, VT, USA
Introduction/Rationale
State mandates are now requiring parents and student athletes to receive information on concussions. The information provided is not standardized and ranges from comprehensive Centers for Disease Control and Prevention packets to school generated handouts. While controlled study of the effectiveness of these efforts remains limited, a baseline questionnaire developed for parents and students athletes could provide a starting point for assessing the efficacy of the concussion information programs.
Method/Approach
Using current multiple-choice test guidelines a set of 25 questions was generated and piloted to provide some baseline measure of parent's and student athlete's concussion knowledge. In addition, 4 short true/false questions were also used to address the current "myths" associated with concussive injuries. Being able to answer these objective questions was supplemented with a short narrative question about how to recognize and handle a concussion event. Issues surrounding the selection of resources and questions used, language, usability and applications is addressed.
Results/Effects
Pilot data, issues and discussion of the Castleton Concussion Quiz (CCQ) provide the basis for discussion of the efficacy and need for such quantitative and qualitative research tools. Behavioral and technological interventions can be aided by this simple baseline measure and help direct more fundamental controlled research protocols.
Conclusions/Limitations
Development of a simple baseline questionnaire to assess parental and student athlete knowledge of concussions is a point of departure for effective behavioral and learning technologies interventions. The issues involved in the development of such measures regarding reliability and validity require discussion. Self report data and new cyber survey techniques also add to the discussion of cost/benefit and usability value.

Functional Analysis of Vocal Stereotypy for an Adult with Acquired Brain Injury
Craig Strohmeier1

1Philadelphia College of Osteopathic Medicine and Bancroft, Brain Injury Services, Lebensfeld Center, Cherry Hill, NJ, USA, 2Bancroft, Brain Injury Services, Lebensfeld Center, Cherry Hill, NJ, USA
Introduction/Rationale
Functional (experimental) analysis (FA) was used to assess vocal stereotypy displayed by an adult with acquired brain injury (ABI). Assessment of vocal stereotypy with FA has been used frequently in other settings, but lack of FA within ABI rehabilitation may stem from the perception of the procedures as overly time consuming and a view that behaviors secondary to neuroanatomical damage after head trauma are not sensitive to environmental changes. This study employed a variation of FA that was conducted rapidly and demonstrated the function of the vocal stereotypy as maintained by socially mediated attention, which provided clear direction for intervention.
Method/Approach
FA was used to assess vocal stereotypy in an adult male with a history of anoxic encephalopathy and subdural hematoma. Four conditions (attention, escape, ignore, and free interaction), each lasting five minutes, were randomly alternated four times each in a multi-element design for a total of 16 sessions (80 minutes). In each condition a specific environmental change (i.e. therapist response) was programmed subsequent to the vocal stereotypy to determine if the test conditions occasioned a differentiated level of vocal stereotypy. Data was recorded using a partial interval recording method, indicating the presence or absence of vocal stereotypy in 20 second intervals.
Results/Effects
Initially, descriptive and indirect functional behavior assessment methods provided correlational data to support hypotheses that the individual's vocal stereotypy was due to escape from an unpleasant task and a direct reduction in anxiety. During the FA, vocal stereotypy emerged clearly as an operant behavior maintained by attention. Extended sessions conducted at follow-up confirmed that attention was the function of the behavior and the escape/direct reinforcement hypotheses from descriptive and indirect functional behavior assessment methods was unreliable and inaccurate. Subsequent treatment sessions stemmed directly from the FA data and successfully employed differential reinforcement of novel vocalizations with attention.
Conclusions/Limitations
The FA demonstrated a clear relationship between the vocal stereotypy and environmental changes. In turn, a distinct route for effective intervention was also developed. Although rehabilitation programs may utilize descriptive and indirect functional behavior assessment, these procedures can be more time consuming than a brief FA, which was 80 minutes total in this case. Furthermore, the treatments derived from descriptive and indirect methods without the confirmation from an FA may have iatrogenic effects. Implications for brief FA methods within rehabilitation settings should be considered further in regard to identifying the operant nature of challenging behaviors after head trauma.

Methodologies Implemented for Students with Brain Injury in a Large Urban School District: A Brain Injury Service Model
Cindy Pahr1,2
1San Diego Unified School District, San Diego, CA, USA, 2EduCLIME, LLC, San Diego, CA, USA
Introduction/Rationale
In 2003, San Diego Unified School District (SDUSD) began implementation of a brain injury service model that involves a streamline between Rady Children's Hospital, SDUSD's Physical and Health Impairments Program and various educational programs throughout the district. SDUSD is the eighth largest school district in the U.S. serving more than 132,000 students from varied ethnic and socioeconomic backgrounds. In many school districts across the U.S., there is a lack of understanding regarding the needs of students with ABI and to how to serve them in the classroom setting. Thus, this population is both vastly under-served and inappropriately served.
Method/Approach
SDUSD's Brain Injury service model is providing a system of staff training, student identification, utilization of best practices in managing brain injury learning and behaviors, fluid placement in a variety of settings and ongoing evaluation.
Targeted lessons are provided to address ABI issues, particularly in the high school ABI class. Students at all grade levels receive specialized support services. The school staffs receive ongoing collaboration and training to understand the students' needs. Extreme behaviors are addressed within existing district programs lessening the expense of private schools. The program assesses each student's changing needs as they evolve through recovery.
Results/Effects
The high school brain injury class is in its seventh year. Students continue to receive services through special education in their neighborhood schools or specialized placement options within the district. Students exiting the hospital are seen prior to discharge to assist with school re-entry. Extensive training is being implemented for the staff working with extreme behavioral issues in an effort to bridge traditional training in behavior with addressing behavior in individuals with brain injury. This is creating a significant and important paradigm shift for the staff in response to behavior/addressing behaviors of students with ABI.
Conclusions/Limitations
SDUSD has continued to move forward providing targeted specialized services and training to support students with brain injuries. The high school class for students with brain injuries is more defined in its organizational structure. A heightened interest from the district's program for students with emotional difficulties helps us bridge a gap in appropriate services for our students with extreme behaviors. In spite of limited funding and resources, SDUSD continues their BI services model, working on how to maintain these important options for our students. Though we face budget cuts, the district's enthusiasm for continuing this vital service model continues.

Activation of Metabotropic Glutamate Receptor 5 Reduces the Acute Neurologic Deficits and Microglia-Associated Neuroinflammation After Traumatic Brain Injury in Rats
Jia Wei Wang
Han Dong Wang
Zi Xiang Cong
Ding Ding Zhang
Nanjing university, Nanjing, China
Introduction/Rationale
Glutamate released by the traumatic brain injury (TBI) acts at the metabotropic glutamate receptors (mGluR), including the mGluR5. Substantial evidence has shown that microglia-associated neuroinflammation is involved in the pathophysiologic processes contributing to the neurologic deficits after TBI. Our previous study indicated that mGluR5 was expressed in active microglia in rats with TBI and in vitro studies have shown mGluR5 activation could inhibit the microglia-associated inflammation induced by LPS and protect the neuron challenged by b-amyloid. There is little known about whether mGluR5 activation could provide neuroprotection and reduce microglia-associated neuroinflammation in rats followed by TBI.
Method/Approach
Rats were randomly distributed into four groups: the sham group, the sham+vehicle group, the TBI+vehicle group, and the TBI+CHPG (selective mGluR5 agonist) group. 250 nmol CHPG were administrated through i.c.v. injection at thirty minutes after TBI. All rats were sacrificed at twenty-four hours after TBI. The neurologic scores and beam-walking scores were evaluated before sacrifice. Wet/dry weight method and Evans blue (EB) extravasation quantifying was used to assess the brain edema. ED1 immunofluorescence was performed. The level of IL-1[beta], IL-6 and TNF-[alpha] were determined by qPCR and ELISA. Fluoro-Jade C staining was used to detect the number of degenerating neurons.
Results/Effects
Post-TBI administration of CHPG could significantly improve the neurologic deficits, ameliorate the BBB impairment and reduce the brain edema induce by TBI. The number of TBI-induced excessive ED1+ microglia was also reduced by treatment with CHPG. Accordingly, the expression of microglia-associated inflammatory cytokines IL-1[beta], IL-6 and TNF-[alpha] and degenerating neurons were inhibited by CHPG treatment.
Conclusions/Limitations
CHPG could provide neuroprotection in rats following by TBI partially through inhibiting the microglia-associated neuroinflammation. However, further researches are needed to elucidate the mechanisms by which CHPG inhibits microglia-associated neuroinflammation.

Processing Speed and Reaction Time: A Highly Fragile Cognitive Construct
Francis Sparadeo
Michael Meyerson
Dmitry Meyerson
Sparadeo & Associates, W. Warwick, R.I., USA
Introduction/Rationale
Processing speed is a cognitive construct that is a fundamental component of general intellectual functioning and is highly susceptible to disruption following neurological insult. Functional imaging studies have demonstrated that processing speed relies on recruitment of network areas including the PFC and the ACC. Processing speed impairment is the most common deficit associated with mTBI. Processing speed impairment has been documented in a myriad of neurological disorders such as multiple sclerosis, ADHD, diabetes, early dementia, learning disability, autism, chronic pain and others. Additionally, processing speed has also been shown to be impaired in such psychiatric disorders as depression and substance abuse.
Method/Approach
This study examined processing speed in several clinical populations and compared these measures utilizing ANOVA and bonferroni follow-up comparisons. The processing speed measures included a simple counting task (25 numbers test), reaction time on a memory task and reaction time on two separate concept formation tasks. Participants in the study were individuals referred for neuropsychological assessment and were divided into 5 diagnostic groups: mTBI (n = 208), cocaine users (n = 8), cannabis users (n = 27), heavy alcohol users (n = 49) and people with major depressive disorder (n = 39). Their test results were compared to healthy normal subjects (255).
Results/Effects
The results of this investigation indicate that mTBI patients were significantly impaired on all measures of speed and performance (this includes a brief memory test and two brief concept formation tests). All other clinical groups were slower on reaction time and general speed measures than the control group with the exception of cocaine abusers whose speed was generally normal but whose qualitative performance was lower than controls. The patients in the Major Depression group were as impaired as the TBI group on processing speed and reaction times for memory and concept formation, while their accuracy on these tasks was generally normal.
Conclusions/Limitations
This study is consistent with the literature in indicating that neurological insult is likely to be manifested in general cognitive inefficiency (slow speed). Furthermore, this inefficiency is easily detected in a direct measure of simple processing speed as well as simple measures of reaction time for memory and concept formation. Major depressive disorder has a similar impact on processing speed as mTBI. Cocaine abusers did not evidence processing speed impairment, however, it is important to note that the cocaine abusers were significantly younger than the other groups and processing speed is impacted by age. Substance use is associated with slow processing.

Introduction/Rationale
Research suggests that people with TBI have difficulty with facial and vocal affect recognition, but few studies have examined these two modalities of perception simultaneously. Thus it remains unclear where deficits in these two modalities co-occur and whether one modality is typically impacted more than the other. The objectives of the current study were to determine: 1) the frequency of isolated impairment of facial or vocal affect versus dual impairment; 2) whether isolated impairment is more prevalent in one modality versus another; 3) to examine factors (e.g. intensity, emotion category) that may influence affect recognition when impairment is present.
Method/Approach
190 participants with moderate to severe TBI, recruited from Canada, USA and New Zealand, were administered the Adult Faces and the Adult Paralanguage subtests from the Diagnostic Analysis of Nonverbal Affect 2. Participants were classified as impaired/not impaired for each modality using the available standardized norms for each subtest.
Results/Effects
Forty (21%) participants were classified as having both facial and vocal affect impairment, 32 (17%) for facial affect impairment only and 26 (14%) for vocal affect impairment only. Both impaired and unimpaired participants found high intensity expressions significantly easier to identify than low intensity expressions for facial, F(1,187) = 271.21,p<.001, and vocal affect, F(1,188) = 117.90,p<.001. Although all participants identified happy facial expressions with greater accuracy than negatively valenced expressions, this difference was significantly greater for participants who were classified as impaired in this modality, F(1, 187) = 32.25, p<.001. No interaction between impairment classification and identification of specific emotion categories was found for vocal emotion expressions.
Conclusions/Limitations
The current study examined facial and vocal affect recognition abilities in a large sample of people with TBI, comparing performance based on the presence/absence of affect recognition impairment. Over half of the participants (n = 98) showed impairment in one or both modalities, with the greatest percentage showing dual impairment.
Facial and vocal affect recognition did not appear to be further hindered by intensity or emotion category since participants classified as impaired/not impaired responded similarly. However, the inclusion only one positive alternative (i.e. happy) may not only have led to artificial agreement by all participants, but also constrained exploration of valence effects.

Introduction/Rationale
Researchers recently reported persistent medical symptoms in adults following brain injury (Masel & DeWitt, 2010). Although described as a chronic disease process in adults, there is limited information about persistent medical symptoms in children. The transition of medical care from pediatric to adult care providers is a quickly growing area of concern. For some adolescents with complex medical conditions, a primary factor for optimal transition is the presence of a medical home. Our objective was to document persistent symptoms and medical home status of adolescents who sustained a childhood brain injury, as well as identify medical and rehabilitation service needs.
Method/Approach
This was an exploratory descriptive qualitative study. Nine participants who were 6 months-16.5 years post injury, enrolled in a two-week community transition program and ten caregivers completed questionnaires about the participant's current medical home and persistent medical symptoms. Semi-structured interviews were conducted with each participant and caregiver. Medical symptoms were confirmed by medical records and supplemented by observations during the program.
Results/Effects
The most common medical complaints were neurologic, cognitive and behavioral/emotional in nature and multiple at-risk behavior patterns were observed. Fatigue was the most commonly reported symptom. In addition, none of our participants met criteria for the medical home. Participants and caregivers were least likely to report effective care coordination and family centered care. Multiple themes regarding the medical system such as lack of a primary care physician and inability to receive needed rehabilitation services emerged.
Conclusions/Limitations
Findings of persistent symptom reports for years past the initial injury and recovery observed in this study support the idea of pediatric brain injury as a chronic disease process rather than a unitary event. Defining brain injury as a medical condition is particularly important for the adolescent population because of potential impact on their transition to higher education, financial, social and occupational independence. Our findings demonstrate limited progress made towards providing comprehensive medical care and promoting access to medical services for this population.

Therapeutic Group Model for Grief and Loss Following Brain Injury
Crystal Hartman1,2
1Denver Options Inc., Denver, CO, USA, 2Colorado Traumatic Brain Injury Trust Fund, Denver CO, USA
Introduction/Rationale
Following a brain injury, individuals experience significant grief and loss related to their change in abilities, role within their systems and overall loss of independence. Acute and sub-acute rehabilitation settings focus on stabilization, acquisition of skills and reintegration; emotional needs are rarely treated. Following discharge many individuals experience issues with grieving loss. There are minimal services offered to address these needs, especially in group settings. Established treatments (Janet Niemeier and GIST Social Skills program) have shown success with treatment in group settings. To meet the ongoing need, a pilot study was developed for a grief therapy group model.
Method/Approach
Eight clients recruited from the Colorado Traumatic Brain Injury Trust Fund Program participated in an eight week Grief and Loss Therapy Group. The group sessions consisted of both psychoeducational curriculum and process oriented tasks. Sessions were 1.5 hours in duration and covered various topics related to grief and loss including impact of loss, emotional response to grief, coping skills and identity development. Pre and post surveys were administered to assess learned knowledge.
Results/Effects
The pilot study began with eight clients (6 females, 2 males). One female ended treatment early and she was excluded from the data. In the pre survey participants scored a baseline of 49% knowledge of the topic with an average score of 12 out of 25 possible points. Following the eight week group, the post survey scored 78% knowledge of the topic with an average score of 19. Participants also provided anecdotal data related to their experiences in the group showing themes of similarity and belongingness; "I am not alone."
Conclusions/Limitations
This treatment model provided therapeutic intervention in a format that can treat multiple clients in a short period of time. The strongest impact was the relationship built between group members. They demonstrated learned knowledge, strong group cohesion and consistent themes of similarity and belongingness. Success of the pilot study provided further grant funding to complete four additional groups. Groups will be extended to 10 weeks and 2 hours per session. The Beck Depression Inventory will be added as a secondary assessment tool. The intension of this therapy model is to provide accessible therapeutic intervention to meet this ongoing need.

SUNY at Buffalo, Buffalo, NY, USA
Introduction/Rationale
The purpose of this study was to evaluate the value of computerized neuropsychological (NP) testing for establishing readiness to return to sport (and school) in adolescents after concussion relative to a standardized exercise treadmill test (the Buffalo Concussion Treadmill Test -BCTT1).
Method/Approach
Retrospective analysis of prospectively collected data. Concussed athletes (n = 59, 46 M, mean age 15.7y) who reported symptom resolution completed Automated Neuropsychological Assessment Metrics (ANAM) computerized testing followed by the BCTT on the same day. ANAM sub-test performance (according to age normative data in the "Sport-High School Reference Data," 2010 ANAM Sports Medicine Battery User Manual) was evaluated. Athletes who exercised to voluntary exhaustion without symptom exacerbation were returned to sport following the Zurich Consensus Conference Guidelines. A telephone follow up was performed with athletes and a parent (for those under 18) asking about return to sport and school difficulties.
Results/Effects
54% of athletes had >=1 (range 1-6) ANAM subtests below average (9th percentile or below) and 22% had >=1 (range 1-4) ANAM subtests clearly below average (2nd percentile or below). All athletes exercised to exhaustion without exacerbation of symptoms on the BCTT and returned to sport. A telephone follow up with 30 athletes 3-41 months (mean 18.2+/-11.4) after return to sport revealed that none had experienced recurrence of symptoms during sport although 15/30 reported some symptoms with school activities. ANAM test performance did not predict symptoms reported on the day of the treadmill test or symptoms upon return to school.
Conclusions/Limitations
The ability of concussed high school athletes to exercise to exhaustion on the BCTT without symptom exacerbation in combination with the Zurich guidelines was 100% successful for return to sport. NP testing, at least in athletes who do not have a pre-injury "baseline" test, does not appear to be useful in the return to sport decision process and was not associated with symptoms in school. Evaluation of the predictive nature of NP testing might have been enhanced if athletes had baseline data. The primary outcome measure, safe return to sport, may not capture subtle cognitive issues represented by NP testing.

Alison Hartwig1
Mary Brownsberger3
Karen Lindgren3
1La Salle University, Philadelphia, Pennsylvania, USA, 2Drexel University, Philadelphia, Pennsylvania, USA, 3Bancroft Brain Injury Services, Cherry Hill, New Jersey, USA
Introduction/Rationale
The current study is part of a series of investigations examining the relationship between brain injury rehabilitation outcomes, measured by the Mayo-Portland Adaptability Inventory (MPAI-4; Malec & Lezak, 2003), and quality of life (QoL), assessed by the WHO QOL-BREF (Chiu et al., 2006). The current study examined the relationship between MPAI-4 items, total QOL score, and four QoL domains (i.e., Physical, Psychological, Social, Environmental). Four MPAI-4 items were examined: Novel Problem-Solving, Self-Awareness, Depression and Leisure/Recreational Activity. We hypothesized that Depression and Self-Awareness limitations would significantly predict lower QoL, and that Leisure/Recreational Activity and Novel Problem-Solving abilities would predict higher QoL.
Method/Approach
Data was collected at Bancroft Brain Injury Services, a post-acute, community-based day treatment rehabilitation program in New Jersey, which serves adults with moderate-to-severe brain injury. Archival data from 51 persons were examined. Participants' mean age was 43.25 years (SD = 11.64). Mean time since injury was 16.88 years (SD = 9.33). Thirty-three participants (65.70%) were male; 18 (35.30%) were female. Forty participants (78.40%) identified as White, nine (17.60%) were African-American, one (2%) was Asian, and one (2%) was Hispanic. MPAI-4 was rated via professional consensus; participants self-reported quality of life.
Results/Effects
Linear regressions were utilized to assess the relationship among individual MPAI items and quality of life. Gender and race did not significantly predict QoL or MPAI scores and therefore were not entered as covariates. Preliminary results indicated that Depression significantly predicted both total QoL(Y = -3.54, X = 62.77, SEb = 1.21, p < .05, R2 = 0.14) and Psychological QoL (Y = -1.34, X = 16.10, SEb = 0.40, p < .05, R2 = 0.17). No significant associations were found among the Leisure, Self-Awareness, or Novel Problem-Solving MPAI-4 items and QoL.
Conclusions/Limitations
The MPAI-4 Depression item significantly predicted lower quality of life in TBI patients at a long-term, post-acute rehabilitation setting. This finding was consistent with previous literature addressing QoL among TBI patients. Thus, depression and mood may be important treatment targets in rehabilitation. The relationship among mood, self-awareness, activity levels, problem solving abilities, and QoL should be further examined. Study limitations included small sample size, the wide range of functional abilities and time since injury within the sample, and the use of individual MPAI items to assess complex constructs. Findings should be replicated using a multi-method assessment approach and larger sample.

1Counseling Services of SWLA, Lake Charles, LA, USA, 2Fielding University, Santa Barbara, CA, USA
Introduction/Rationale
A 38 year old male experienced toxic gas inhalation, as well as exposure to a massive explosion on an oil rig drilling platform resulting in significant physical, cognitive and affective impairments. The purpose of this study is to discuss the psychological consequences as a result of the trauma, thereby adding to the knowledge base of psychological and neurological understanding.
Method/Approach Participant:
JD, a 38 year old male, acquired significant affective, physical, and cognitive impairment associated with noxious gas inhalation and resulting trauma due to witnessing a massive oil drilling platform explosion and the subsequent loss of life of personal associates.
Procedure:
A neuropsychological evaluation was conducted on an outpatient basis in August of 2010. After completing the consent and release forms, the client was administered 12 instruments over a two day period. The primary assessments were the Wechsler Adult Intelligence Scales Fourth Edition; Wide Range Achievement Test, Fourth Edition; Beck Depression Inventory, Second Edition and Beck Anxiety Inventory, among others.
Results/Effects
The results of the neuropsychological evaluation suggested a decline in overall cognitive ability and physical functionality. Additionally, there were deficiencies in memory (recent), executive functions (insight and abstraction), and language processing.
Conclusions/Limitations
Reported hyper vigilance, middle and terminal insomnia, intrusive thoughts and sexual dysfunction may be indicative of post traumatic disorder (PTSD). Relatives reported a distinct deterioration of social skills and personality normalcy. Elevations on measures of depression and anxiety were significant.

Integrating Erickson Hypnosis Techniques and Cognitive Behavioral Strategies for the Treatment of Chronic Pain in Post-Concussion Syndrome
Lawrence Dilks1
Jacqueline Bourassa2
1Counseling Services of SWLA, Lake Charles, LA, USA, 2McNeese State University, Lake Charles, LA, USA
Introduction/Rationale
Many concussion injuries result in a chronic pain disorder that is often reported as diffuse and lacking focus. Frequently chronic pain leads to a number of secondary issues that become intertwined and resistant to intervention. Cognitive Behavior Therapy (CBT) has won approval as an evidenced-based approach to the treatment of emotional disorders and has shown promise in the treatment of chronic pain.
This abstract focuses on discussing and demonstrating the integration of CBT and Erikson hypnotic techniques with seven individuals, who were involved in an offshore explosion, sustained concussion and were resistant to traditional psychotherapeutic intervention for pain.
Method/Approach Participants:
Seven males were referred for individual counselling as a consequence of injuries sustained in an explosion. Each possessed a concussion, mild to moderate in nature and suffered from chronic diffuse pain, depression and anxiety.
Therapeutic Methods:
A traditional approach to CBT was failing to achieve the determined therapeutic goals due to resistance. Consequently, Erickson techniques were integrated. These involved endorsing the resistance, therapeutic stories, distraction, visual imagery, mirroring and directed attention. These were blended with CBT strategies of redefining events, autogenic phrases, structured relaxation exercise, and identifying illogical and logical ideas.
Results/Effects
Clients were monitored for compliance and symptom relief by using the Beck Depression Inventory, second edition and self-report. Symptom resolution occurred slowly over time until discharge.
Conclusions/Limitations
By discussing and demonstrating the integration of two very different therapeutic techniques, participants may discover ways to enhance therapeutic activities and bring about improved resolution in counselling and cognitive rehabilitation. In this particular endeavor, the integration of CBT and Erickson techniques resulted in greater compliance and participation. The success suggests that cognitively impaired persons may benefit from the integration of other forms of intervention beyond counselling and benefits might be found for vocational training and the treatment of Post-Traumatic Stress Disorder. Further research is warranted.

Neuronal Pentraxin 1: A Molecular Determinant of Hypoxic-Ischemic Brain Injury
Mir Ahamed Hossain
Hugo W. Moser Research Institute at Kennedy Krieger and Johns Hopkins Univ. School of Medicine, Baltimore, MD, USA
Introduction/Rationale
Neonatal hypoxic-ischemic brain injury is a leading cause of severe neurological disabilities and mortality in surviving infants and children; affecting the life of all ages and populations worldwide. Nonetheless, the mechanism(s) involved in this pathology in the developing brain remain inadequately understood. Therefore, it is of utmost importance to better understand the mechanism(s) underlying the hypoxic-ischemic injury in neonatal brain to devise effective therapy. Here, we report the induction of a novel neuronal protein 'neuronal pentraxin 1' (NP1), a member of a subfamily of "long-pentraxins", in neonatal brain injury following hypoxia-ischemia (HI), and that NP1 gene silencing is neuroprotective.
Method/Approach
We have used wild-type (WT) and NP1 knockout (NP1-KO) mouse cortical and hippocampal cultures, modeled in vitro, following exposure to oxygen glucose deprivation (OGD) that resembles human stroke episode and in vivo neonatal animal model of HI to examine the role of NP1 in hypoxic-ischemic brain injury. NP1 induction was determined by immunofluorescence, RT-qPCR and protein. To evaluate brain injury, infarct volume was measured in the injured hemisphere.
Results/Effects
Elevated expression of NP1was observed in cortical layers, hippocampal CA3, and CA1 areas of WT brains following HI. WT brains showed marked infarcts and volume loss in the ipsilateral-cerebral hemisphere but not the NP1-KO brains after HI. Primary cortical and hippocampal WT neurons showed an OGD time-dependent NP1 induction and cell death. NP1 gene silencing by siRNA in WT neurons, and NP1-/- neurons were significantly protected, whereas, overexpression of NP1 in WT and NP1-/- cells with pLenti6v5-Nptx1 further enhanced OGD-induced cell death. NP1 co-localized with AMPA GluR1in WT neurons, and that AMPA-induced cell death was significantly decreased in NP1-/- neurons.
Conclusions/Limitations
This study identifies NP1 as a mediator of hypoxic-ischemic injury in the brain. This is the first evidence for a pathophysiological function of NP1 in central neurons. Together these results clearly demonstrate a role of NP1 in the coupling between HI and neuronal death at the level of excitatory cascade. Our findings point to a novel molecular target of brain injury, and will foster new strategies for the clinical management of neonates suffering from HI insult. Supported by NIH RO1 NS046030 grant.

Training of Gist-Based Strategic Reasoning in Adolescents with Chronic Traumatic Brain Injury

Sandra B. Chapman
Nellie Evenson
Kami Vinton
Center for BrainHealth, The University of Texas at Dallas, Dallas, TX, USA
Introduction/Rationale
There is an urgent need to study the effects of cognitive training among adolescents whose higher order cognition is impaired by sustaining a traumatic brain injury (TBI). In contrast to good recovery of previously acquired skills and self-care activities in most adolescents with TBI, executive cognitive functions are often persistently impaired and implicated in poor school performance and social maladjustment, yet there has been limited focus on training to enhance cognitive function at chronic stages. Based on use-dependent neuroplasticity evidence that brain networks can be changed and cognitive function improved given intensive stimulation, this gap in research warrants attention.
Method/Approach
This study examined the effects of two forms of strategy-based training, including training of gist-based reasoning versus fact-based remembering, on ability to abstract meaning and recall details in 20 adolescents (ages 12-20) at least six months post-TBI. Impetus for this was based on research indicating a residual impairment in ability to extract "gist" or abstract meanings from information after TBI. Additionally, ability to encode meaning at an abstract rather than explicit level has been shown to enhance memory for details. Participants in each training group completed eight individual 45-minute sessions over one month, as well as pre- and post-training assessments.
Results/Effects
Preliminary results from the gist-training group revealed significantly improved strategic reasoning performance after training (p = .0002***) as well as improved ability to provide generalized interpretive statements (p = .0418*) and recall details (p = .0384*) from texts. Additionally, for the gist-training group, significant improvement was seen in untrained measures of executive function, namely those of working memory (p = .0318*) and inhibition (p = .0471*). For the fact-training group, preliminary findings indicate no significant gains in any of these trained or untrained domains.
Conclusions/Limitations
Overall, the implication is that a top-down complex reasoning approach (gist-training) is effective in remediating higher-order cognitive deficits in adolescents with chronic-stage traumatic brain injury. Further, top-down modulation of information has a positive impact on bottom-up processes such as recall of details. Additionally, preliminary evidence indicates benefits of the gist-based reasoning training on untrained measures of executive control such as working memory and inhibition. Future investigation should include long-term follow-up, determining if the effects of training on constructing gist meaning and/or remembering facts are maintained over time, as maintenance of training effects is critical for potential clinical application.

Introduction/Rationale
Major depressive disorder (MDD) is perhaps the most common and disabling condition experienced by individuals with traumatic brain injury (TBI). Data shows that less than half of individuals with TBI and MDD receive any depression treatment and most patients prefer counseling over pharmacotherapy. Common barriers to depression treatment include difficulty with cognition, transportation, mobility, and accessibility. We developed an intervention aimed at overcoming these barriers. We describe the design, progress, and early data from a randomized clinical trial of in-person and telephone administered cognitive behavioral therapy (CBT) for persons with complicated mild to severe TBI and major depressive disorder (MDD).
Method/Approach
We developed a randomized controlled trial with three arms: in-person CBT, telephone CBT, and Usual Care. We utilized choice-stratified randomization, stratified by TBI severity (complicated mild/moderate or severe). The CBT intervention consists of 12 sessions over 16 weeks. The primary outcome is change in depression severity on the Hamilton Rating Scale for Depression at 8, 16, and 24 weeks assessed by a rater blinded to treatment condition. We also assess depression with the Patient Health Questionanire-9 (PHQ-9) at each session. We aim to recruit 90 adults within 10 years of TBI from hospital and community settings throughout the United States.
Results/Effects
We modified an empirically-supported telephone-based CBT protocol to accommodate cognitive impairments common in persons with TBI. We describe the challenges associated with modifying CBT for persons with TBI, including engaging support persons, monitoring and maintaining treatment fidelity, recruiting, treating, and retaining depressed persons with TBI. We began recruiting participants in 2008 and have enrolled 88. Preliminary data from PHQ-9 depression scores from intervention sessions will be presented. Thus far, of 44 participants who have completed the CBT intervention, 24 (55%) responded (>50% drop in PHQ-9). Telephone CBT appears to be equally efficacious with higher retention rates than in-person CBT.
Conclusions/Limitations
No randomized controlled trials of psychotherapy for MDD have yet been published. Preliminary findings from this RCT suggests that CBT for MDD may be feasible, acceptable and efficacious in persons with TBI. Telephone CBT holds particular promise for enhancing access and adherence to treatment without any decline in efficacy. Updated adherence and depression data will be presented. Because data collection is still ongoing, these preliminary findings must be interpreted with caution.

Expected Payment Source for Traumatic Brain Injury Emergency Department Visits in the United States
Michael Lionbarger
William Pearson
Centers for Disease Control and Prevention, Atlanta, GA, USA
Introduction/Rationale
Traumatic Brain Injury (TBI) is a serious public health problem in the US. According to recent CDC estimates, the average annual incidence of a TBI alone and TBI in combination with other injuries or conditions was approximately 1.7 million during 2002-2006. The number of TBI cases seen in EDs increased from approximately 1.25 million in 2002 to 1.4 million in 2006. This analysis used national data to describe expected payment source of patients who were seen in an ED with a TBI.
Method/Approach
The 2009 National Hospital Ambulatory Medical Care Survey-Emergency Department (NHAMCS-ED) data were used to examine expected payment source for ED visits of patients where TBI was listed as one of three possible diagnoses. TBI was identified using International Classification of Diseases, Ninth Revision Clinical Modification codes obtained from ED records. Expected payment source was classified into three categories including private insurance or worker's compensation, Medicare or Medicaid, or Self-Pay or No Charge. Estimates and 95% confidence intervals were calculated for each of these measures.
Results/Effects
The majority of patients with a TBI-related ED visit had private insurance or worker's compensation as the expected payment source (46.2%, 40.6% - 51.9%). Medicare and Medicaid were the expected payment source for approximately one-third (34.9%, 30.1% - 40.1%) of the TBI-related ED visits while Self-Pay and No Charge made up nearly one-fifth (18.9%, 14.8% - 23.7%) of TBI-related ED visits.
Conclusions/Limitations
There is an increasing trend in TBI-related ED visits since 2002. The expected payment source for TBI-related ED visits are varied. From these analyses, it is unclear if payment source was a potential barrier to seeking treatment for a suspected TBI. Additional analysis will need to examine characteristics of the patients with TBI-related ED visits to target improved prevention strategies to limit the economic burden of TBI in the US.

Introduction/Rationale
Pediatric TBI results in a range of adverse cognitive, behavioral, and social consequences. Self-regulation, planning, and other higher order executive function skills may be particularly impaired. Families can also experience elevated burden and distress. There are few validated interventions for children and teens and their families dealing with a traumatic brain injury (TBI). The goal of the NIDRR-funded Rehabilitation Research and Training Center for Pediatric TBI Interventions is to advance the field of interventions for pediatric TBI through a systematic and coordinated approach of development, replication, and dissemination of promising intervention practices.
Method/Approach
The Center is conducting trials focusing on improving: 1)parenting skills and behavior problems in children 3-9; 2)functioning in teens 1-18; and 3)attention and executive functions in school-age children. Through the Common Data Elements initiative, we are developing a toolbox of measures that can be used to assess functional outcomes. The first trial compares short (6 sessions) and long (16 sessions) web-based parent-skills programs to internet-based resources. The second trial compares family-centered online problem solving (TOPS) to one-on-one problem-solving (TOPS-TO) or access to internet resources (IRC). Finally, Attention Intervention Management (AIM) examines the efficacy of cognitive training in remediating attention post-TBI.
Results/Effects
The three trials are underway and have recruited a total of 135 participants. We will present preliminary evidence from each of the trials including acceptability/feasibility, satisfaction and improvements in targeted child and family outcomes. Overall, families have responded positively to each of the interventions and have expressed a high level of satisfaction with the information and skills that they have learned. Participating children and adolescents also expressed satisfaction with the individual problem-solving and attention management programs. Moreover, families and participating adolescents reported improvements in child behavior and functioning in some but not all domains, supporting the utility of these programs.
Conclusions/Limitations
Given the high incidence of pediatric TBI and risk for long-term behavioral and family morbidity, it is critical to develop an evidence base regarding developmentally-targeted interventions and reliable and valid tools for assessing functional outcomes. We will discuss the progress that the RRTC for Pediatric TBI Interventions has made in addressing this goal and directions for future research. Given the heterogeneity of the population with respect to injury severity and family characteristics it is critical to identify which approaches are likely to be most effective for differing levels of severity and psychosocial burden.

Mashhad University of Medical Sciences, Mashhad, Iran
Introduction/Rationale
Traumatic brain injury (TBI) is one of the most common cause of morbidity and mortality. Severe TBI is commonly associated with coagulopathy that is related with complications like delayed intracranial hematoma (DICH) or ischemia, causing poor outcome. Despite many advances, management of the coagulopathy in TBI is still challenging. Herein we evaluated the effect of high dose enoxaparin on the severe TBI outcome.
Method/Approach
Twenty-four patients were entered in this study, a double blinded clinical trial, in two parallel groups, taking either enoxaparin or normal saline (N/S) subcutaneously. The inclusion criteria were severe closed head injury, Glasgow coma scale between 5 and 8, no intracranial hematoma required evacuation, no coagulopathy, and onset of treatment within five hours of trauma. The enoxaparin (0.5 mg/kg) was injected within five hours of trauma, then every eight hours for total four doses. The clinical findings, laboratory data, imaging and Glasgow outcome scale were evaluated between two groups during hospitalization and at discharge.
Results/Effects
Out of 24 patients, 12 patients received enoxaparin (enoxaparin group, EG) and 12 normal saline (placebo group, PG). There was no difference between two groups for appearance of new intracranial hematoma (ICH) or ICH enlargement (2 in EG versus 1 in PG, p = 1.000). However the good recovery was double in EG (7 patients, 58,3%) in comparison of PG (3 patients, 25%), the difference did not reach any significancy (p = 0.098). There were two dead in PG and one in EG (p = 1.000).
Conclusions/Limitations
The result of this study showed that using high dose enoxaparin could be safe and could result in better outcome in severe TBI without significant intracranial hematoma.

Introduction/Rationale
Traumatic brain injury (TBI) is among the most common causes of acquired disability in childhood with peak incidence in early childhood and adolescence. Emerging or intensifying behavior problems are among the most common and problematic consequences with 1/3-2/3 of children with severe injuries experiencing clinically significant behavioral symptoms during the initial year post injury. Secondary ADHD and difficulties with emotion control and self-regulation are particularly common and troublesome, placing children at risk for re-injury as well as social and legal difficulties. Thus evidence-based interventions to reduce behavioral morbidity in adolescents are critically needed to facilitate successful transition to adulthood.
Method/Approach
Children ages 12-17 who sustained a moderate to severe TBI in the past six months were recruited from five centers and randomized to receive Counselor Assisted Problem Solving (CAPS; n = 66) or access to internet resources on TBI (IRC; n = 66). CAPS involved an initial face-to-face session and six-eleven web-based sessions coupling didactics/exercises on problem-solving, self-regulation and communication with synchronous videoconferences with a therapist who implemented the problem-solving process. The IRC group received links to web-based resources on TBI. Child behavior, as measured by the Child Behavior Checklist (CBCL), was assessed prior to treatment and at a six-month follow-up.
Results/Effects
The groups were well-matched with respect to demographics, injury severity, and pre-morbid functioning. The child's grade at the time of injury moderated treatment efficacy with greater effects of CAPS among high-school age participants. Among high-school age participants, the CAPS group (n = 26) had significantly greater improvements in externalizing behaviors, aggressiveness, ADHD behaviors, and conduct problems than did the IRC group (n = 33). Corresponding effect sizes were moderate (d = .5). Conversely, there were no group differences and minimal improvements among children who sustained their injuries in middle school, suggesting that CAPS may be particularly effective for older adolescents.
Conclusions/Limitations
This was among the first large RCT to examine a post-acute family-centered intervention to reduce behavioral morbidity in adolescents with TBI. Findings provide support for the efficacy of CAPS in reducing externalizing behavior problems and aggression among older adolescents (high-school age). Thus, web-based problem solving approaches may be helpful in facilitating successful transition to adulthood among older adolescents with TBI. For younger adolescents, alternative approaches focusing more on environmental supports or more intensive interventions (> 12 sessions) may be required to effectively support behavioral recovery.

Transition to School Following TBI: Qualitative Analysis of Parents' Experiences
Cynthia Plotts
Paul Jantz
Texas State University, San Marcos, TX, USA
Introduction/Rationale
Children who sustain traumatic brain injury (TBI) often experience needs for which special education, or other accommodations allowed by law, may be effective. The research literature has recently expanded regarding needs and outcomes of individuals with TBI, with some attention to family needs. However, experiences of parents during this process of transition from medical and rehabilitation settings to school, particularly the personal, qualitative experiences have not been explored in the research literature. The purpose of this study is to acquire and analyze qualitative information gathered through interviews regarding parents' experiences in their children's transition to school following TBI.
Method/Approach
An online survey for parents of individuals with TBI was developed using Snap Survey software (Version Snap 10, 2009). Since no database with parent contact information was accessible, the survey was disseminated through relevant websites, email contacts and recruitment through conference presentations, beginning in March 2012. Respondents to the survey were offered a telephone interview to explore personal experiences in the transition process. For those respondents who provide informed consent, telephone interviews are conducted using a semi-structured qualitative interview form, with analysis completed using the NVivo qualitative data analysis software program (Version 9, 2010).
Results/Effects
Telephone interviews are conducted as informed consent was received. To date, we have 20 completed surveys with telephone interviews on 1/2 of these. The funded study concludes in March 2013. We anticipate most interview data to be analyzed by September 2012. Themes include the: (1) complex and changing diagnostic picture after TBI that makes eligibility and classification for school-based services a specialized process; (2) relationship between severity, age and repeated events of TBI to efficiency and effectiveness of transition process; (3) changes in family and social relationships; and (4) need to streamline release of records across settings.
Conclusions/Limitations
Parents of individuals with sustain TBI want to be "heard" by individuals in position to affect policy and practice. The world of medicine, rehabilitation and school services is daunting, with multiple disciplines, assessments and terminology involved; concurrently, families are trying to adjust cognitively, emotionally and financially to their child's altered status. Limitations of this study include generalization of findings outside Texas, selective response to the survey and interview, the "pilot" structure of the survey and qualitative interview; indirect access to the population of parents of children with TBI through school and other provider contacts, and the preliminary status of results.

Healthcare Access and Socioeconomic Status among African-Americans with Traumatic Brain Injury Compared with the General Population
Lee Saunders
James Krause
Medical University of South Carolina, Charleston, SC, USA
Introduction/Rationale
The objective of this study was to identify the extent to which African-Americans with traumatic brain injury (TBI) have equal healthcare access and comparable socioeconomic status (SES) compared to African-Americans in the general population.
Method/Approach
Potential participants were identified through the South Carolina Traumatic Brain Injury Surveillance System Registry. There were 281 African-American participants, aged 18 years or older, injured with TBI in South Carolina who responded to a mail-in survey. Data from the 2009 Behavioral Risk Factor Surveillance System (BRFSS) were downloaded for comparison.
Results/Effects
Participants with TBI had lower SES, as defined by education and household income than persons in the general population. Persons with TBI were also more likely to have more than one person they thought of as their personal doctor (compared with only one), were more likely to have been unable to see a doctor in the past 12 months because of cost, were less likely to have had a routine check-up in the past year, and were more likely to have no health care coverage. The main reasons for no coverage were lost job, unaffordable, and lost Medicaid eligibility.
Conclusions/Limitations
African-Americans with TBI have less access to care and lower SES than African-Americans in the general population. Persons with a TBI are a vulnerable population, and reduced access to health care could create even wider disparities in health outcomes.

Introduction/Rationale
Identifying those at risk for post-traumatic emotional disorders (PTED) is an ongoing challenge. While there is some evidence that those with traumatic brain injury (TBI) are more susceptible to PTED, little association has been found between assigned overall injury severity and PTED. Using a cohort of trauma survivors with a variety of injury types and severities, our objective was to quantify the relationship between self-reported PTED and physical disability.
Method/Approach
Trauma clinic patients were asked to complete Rivermead Post-Concussive Symptoms Questionnaires (RPQ) and the 12 Item Short Form Health Survey (SF-12), previously validated surveys designed to measure symptoms post-concussive syndrome (including PTED) and relative health quality of. Emotional factor components (RPQ) and physical disabilities (SF-12) were collated. The independent relationship between PTED and physical disability was explored using multivariate logistic regression models controlling for brain injury severity, age, gender, insurance status, shock, overall injury severity score, and admission Glasgow Coma Score. Differences in the relationship between PTED and physical disability by brain injury severity were tested using interaction terms.
Results/Effects
Over a 14 month period, 384 patients had both RPQ and SF-12 forms completed. The prevalence of PTED was 17.4% (n = 67) and the prevalence of relative self-reported physical disability was 63.5% (n = 244). PTED was found to be independently associated with physical disability. Those patients with self-reported physical disability had 4 fold greater odds of also reporting PTED (aOR 4.25, 95% CI 1.17-15.44, p = 0.03). The severity of brain injury did not change the intensity of the relationship between physical disability and PTED (p-interaction = 0.8 for mild TBI, p-interaction = 0.4 for moderate/severe TBI).
Conclusions/Limitations
Unlike anatomical scales of injury severity, self-reported measures of PTED and physical disability were correlated. This correlation persisted after controlling for TBI. In the ongoing struggle to identify those survivors at most risk for PTED, it is necessary to consider measures outside assigned injury type, or severity. Patient self-report may provide more insight and indirectly capture coping strategies and patient factors undetected by traditional measures of severity.

How Many Traumatic Brain Injured Patients Are Hospitalized in Level I or II Trauma Centers?

Jeneita Bell
Christopher Taylor
Likang Xu
Centers for Disease Control and Prevention, Atlanta, GA, USA
Introduction/Rationale
Among all injuries, traumatic brain injury (TBI) stands out as a major burden in terms of injury-related mortality and costs. Most moderate to severe TBI is seen in hospital settings. While level I or level II trauma centers have access to neurosurgical care on a 24-hour basis, the proportion of TBI-related hospitalized patients seen in these settings has never been answered in the literature. When comparing trauma center hospitalizations to all hospitalizations, differences in multiple trauma, or multiple injuries, and length of stay (LOS) across hospital settings were expected.
Method/Approach
Using Centers for Disease Control (CDC)defined TBI coding definitions from the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM), the total number of TBI hospitalizations was obtained using 2009 data from the National Hospital Discharge Survey. A TBI case was defined as TBI alone or in conjunction with other injuries or conditions. The total number of TBI-related hospitalizations seen at level I or II trauma centers was calculated with ICD-9-CM TBI codes using 2009 admission data from the National Trauma Data Bank.
Results/Effects
For 2009, the total number of US TBI-related hospitalizations, including people who died while hospitalized, was 361,146. The total number of patients hospitalized with TBI at a level I or II trauma center was 196,235. Thus, 54% of all TBI-related hospitalizations occurred in level I or II trauma centers. The LOS for all TBI-related hospitalizations was 5.92 days (95% CI: 5.22-6.62). The LOS for all TBI-related hospitalizations at a level I or II trauma center was 6.62 days (95% CI: 6.06-7.18). Multiple trauma among TBI patients was more common in trauma centers (83%) compared to all hospitalizations (63%).
Conclusions/Limitations
Utilization of trauma center resources for TBIs may be low considering the established lower mortality rate associated with treatment at trauma centers. The presence of multiple trauma appears to be a determining factor in trauma center care admissions. Given that adherence to the Brain Trauma Foundation guidelines is higher for severe TBI in trauma centers, a better understanding of hospital destination decision making is needed for TBI injured patients.

Rehabilitation and Restorative Interventions based upon Performance-Based Physical Capacity Evaluation, a Work Physiological Model
Theodore Becker1,2
Janet Mott1
1Brain Injury Association of WA, Seattle, WA, USA, 2EPI, Everett, WA, USA
Introduction/Rationale
Post acute care of individuals who have sustained brain injuries includes various therapies to rehabilitate and restore practical functions for activities of daily living including work. The introduction of restorative work physiological science provides objective criteria upon which evidenced based practice can judge the return to work tolerance of these individuals. Utilization of the performance-based physical capacity evaluation establishes the foundation for the development and coordination of required services by the life care planner, vocational rehabilitation counselor, and/or case manager.
Method/Approach
The Performance-Based Physical Capacity Evaluation utilizes predictive work physiological science to determine the presence or absence of fatigue, and to quantitatively determine how many hours an individual who has sustained a brain injury can devote to work tasks. By means of repetitive measurements of oxygen consumption, energy expenditure, and heart rate, the direct correlation of these factors establishes, in an objective process, the tolerance for work and related activities of daily living for the individual.
Results/Effects
The completion of a Performance-Based Physical Capacity Evaluation results in the establishment of baseline objective data and the prediction of the needed process for restoration of stamina and endurance. The life care planner, vocational rehabilitation counselor, and/or case manager then initiates the necessary and required services based upon objective criteria to facilitate the individuals becoming as independent as possible.
Conclusions/Limitations
For many individuals who have sustained brain injuries, the physical issues of reduced stamina and endurance become significant barriers in their capacity to engage in work activities, as well as in the performance of other activities of daily living. Utilizing Performance-Based Physical Capacity Evaluation, a work physiological model, objective assessment of stamina and endurance occur. Rehabilitative and restorative therapies are planned based upon objective data and adhere to a model for objective measurements of oxygen consumption, energy expenditure, and heart, to further evaluate improvement.
Limitations include the lack of trained personnel, multiple geographical locations, and fee for service funding.

Introduction/Rationale
Outcomes following a sports-related concussion are quite variable, with most recovering quickly but others lingering for months. Appropriate post-concussive management has the potential to improve long term outcomes. In the last decade, sports concussion clinics have evolved to meet this goal. However, there is little consensus on what the components of a comprehensive sports concussion clinic should include. The primary objective of this study was to elucidate the degree and types of variation that exist among the services provided by concussion clinics throughout the U.S. treating sports-related concussions.
Method/Approach
We performed an internet survey of a convenience sample of sports concussion clinics identified via internet-based search and personal communication. A total of 30 clinics were sent a 16 question survey asking about their clinic, personnel, cliental, and management plans. All responses were anonymous; the identity of respondents could not be identified.
Results/Effects
Response rate was 37% with the volume of patients seen per month ranging from 10 to >200. Provider types ranged from M.D. and Ph.D., to nurse practitioners and athletic trainers. MD/PhD provider area of expertise included internal, emergency, family, rehabilitation, and sports medicine, as well as neuropsychology. Affiliated academic department included rehabilitation, orthopedics, medicine, and neurosurgery. Although most (91%) clinics offered "in-office" computerized cognitive testing, "out-of-office" services offered varied, ranging from psychological testing (25%) and balance testing (45%), to EEG (27%), and blood testing (27%). 31% of clinics reported not prescribing medications to their concussion patients.
Conclusions/Limitations
The results from concussion clinic respondents suggest a substantial degree of variability in provider types, practices and services provided. This is an important first step in exploring the degree to which variation in clinical practices among sports concussion clinics influence outcomes. Wide variation in clinical practice, coupled with significant variation in outcome, suggests that post-concussive management could be improved. Clinical effectiveness trials may best be able to identify the aspects of post-concussion care most likely to improve outcome.

Robin Harwick
Ann Glang
Bonnie Todis
Center on Brain Injury Research and Training; the Teaching Research Institute of Western Oregon University, Eugene, OR, USA
Introduction/Rationale
Cognitive impairments are a serious consequence of acquired brain injury (ABI). Surveyed professionals indicate they lack evidence-based training practices for teaching their clients to effectively use assistive technology for cognition (ATC). ATC refers to systems such as tablets and smartphones used to compensate for cognitive impairments. Researchers at the Center on Brain Injury Research and Training (CBIRT) developed and experimentally evaluated the TATE (Training Assistive Technology in the Environment). The ATC Toolkit assists trainers in: (1) selecting an appropriate device matched to a client's needs and preferences; and (2) training ATC skills and routines to master everyday environments.
Method/Approach
A mixed methods approach was employed to develop the Toolkit. Themes from focus groups involving clinicians, survivors, and family members were incorporated into the prototype Toolkit, which was then pilot tested by four trainers and clients with ABI. A single-case experimental study was also conducted to determine the impact of using the Toolkit to train a 50-year old female, with moderate-severe cognitive impairments due to ABI, to use ATC for work-related tasks. The Toolkit was also field tested among rehabilitation professionals adn caregivers nationwide.
Results/Effects
With the use of the Toolkit, the 50-year old female's work performance improved significantly after she was systematically trained to use her device across work routines. The results of the field testing among rehabilitation professionals and caregivers, nationwide, are not yet available.
Conclusions/Limitations
The comprehensive approach to product development allowed for the researchers to: (a) explore in detail the constraints trainers face in supporting clients in their use of ATC (PAR focus groups); (b) experimentally evaluate the real-life impact of systematic trainign of ATC for a client with ABI (single case study); and (c) evaluate the imapct of using the Toolkit on trainers' self-efficacy (field testing). Taken together, these results compliment previous research supporting the incoporation of systematic training applied to ATC into clinical practice (e.g. Ehlhardt, Powell, Glang, Todis, Ettel, Sohlberg & Albin, 2012; Ehlhardt, Sohlberg, et al, 2008; Sohlberg et al, 2007).

Introduction/Rationale
Abusive head trauma (AHT) causes significant pediatric morbidity and mortality. The incidence of AHT has increased during the past decade due to the economic recession. Despite evidence of poor long-term developmental and behavioral outcomes, virtually no post-acute interventions exist to facilitate long-term recovery. Given the centrality of family and the parent-child relationships on recovery, interventions to improve parenting skills may be particularly beneficial in improving child behavioral outcomes. To meet the needs of this population, the efficacy of a web-based intervention, with live coaching on parenting skills and parent-child interactions, was tested.
Method/Approach
A small randomized trial compared the efficacy of a web-based positive parenting skills intervention (I-InTERACT) to internet resources access (IRC). Participants included families of 8 children, aged 3-9 years, who had experienced an AHT and were well matched in terms of demographic characteristics. All families received computers, high-speed internet, and links to brain injury resources. In I-InTERACT, a trained counselor guided families through a 6-month online parenting skills-building program, while IRC families did not receive the I-InTERACT program. Parenting skills and child behavior were assessed at baseline and 3- and 6-months post-baseline.
Results/Effects
Group differences were assessed using ANCOVA. Participants in the I-InTERACT group displayed significantly higher rates of targeted positive parenting behaviors (specific praise, behavioral descriptions) at 3- and 6-month follow-ups compared to those in the IRC group. The I-InTERACT group had significantly lower levels of behaviors that parents were trained to avoid at follow-up, as well. Trends toward improvement were also noted in parent-reported child behavior with regard to the number of conduct problems a child displayed and the intensity with which they occurred, as well as for internalizing problems, externalizing problems, and oppositional defiant disorder problems.
Conclusions/Limitations
This study provides preliminary evidence for the efficacy of a web-based positive parenting skills intervention in improving parenting skills and child behavior for families whose child has experienced an AHT. I-InTERACT was well received by the participating families, and they exhibited positive changes in their interactions with their child. Overall, this intervention is likely to reduce the risk of long-term behavioral problems and disability, in young children at risk for long-term disability from AHT, in a cost-effective manner, and the intervention fulfills the large unmet need currently experienced by children with AHT and their families.

Introduction/Rationale
Disruption of cognitive abilities and educational performance is commonly observed after pediatric traumatic brain injury (TBI). Among the most persistent sequelae are deficits in behaviors associated with executive functions (EF), including attention, inhibition, organization, and self-monitoring. However, performance-based tests of general cognitive, EF, and academic skills do not consistently predict functional outcomes beyond the effect of injury severity. Research suggests a discrepancy between academic skills and educational outcomes after pediatric TBI, with age appropriate academic skills despite difficulties in school. The current study proposes that EF behaviors mediate the association between injury severity and educational outcomes following pediatric TBI.
Method/Approach
A mediation model will be tested wherein EF behaviors apparent in everyday settings and cognitive performance mediate the association between injury severity and educational outcomes. It's hypothesized that the path from EF to educational outcomes will be significantly stronger than that from cognitive test performance. 132 adolescents who were hospitalized for moderate to severe TBI were recruited to participate in a randomized clinical intervention trial. Socioeconomic status and intervention designation were included as moderators. BRIEF parent- and self-reports, WASI, CVLT, and Wechsler PSI were collected within 6 months post-injury; educational outcomes were measured using the CAFAS 12 months later.
Results/Effects
Analyses are ongoing, thus, preliminary results are presented here; model results will be included in the conference presentation. The final group of 132 subjects included 65.15% males, 19.7% non-whites, and 38.63% adolescents with severe TBIs. The mean age of injury was 14.54 years (SD = 1.74) and mean time since injury at baseline was 3.56 months (SD = 1.74). Previous research using this sample found significant correlations between parent-report BRIEF and CAFAS educational scores at baseline: OR (CI) = 1.09 (1.04, 1.15), p < 0.01. Parent- and self-reports on the BRIEF were also significantly correlated at baseline, r = 0.51, p< 0.0001.
Conclusions/Limitations
Clinicians and researchers working with youth after TBI would benefit from increased ability to accurately predict educational outcomes in this population. Currently, cognitive performance-based tests provide little additional predictive value beyond the effect of injury severity. The results of the current study will clarify the role of EF in everyday settings in predicting educational outcomes after pediatric TBI. The results will promote development of individualized interventions as well as more accurate prognosis for adolescents who have sustained a TBI.

Introduction/Rationale
Minor traumatic brain injury (mTBI or concussion) has seen changes in resources devoted to education, and awareness as well as structured limitations on athletic concerns. Few studies, to date, have attempted to determine whether, increased occurrence is related to change in injury patterns, or to improvements in physician and public awareness and diagnosis. Objectives: To determine if mTBI rates are increasing faster than other traumatic injuries and whether detection is related to better diagnosis, or to increased occurrence.
Method/Approach
The Emergency Department (ED) and Trauma Center records were analyzed at ED and Trauma Centers in 2 metropolitan areas for the past decade 2000-2010. Trauma registries and the ED database were analyzed for trauma admits, ED visits and mTBI rates and treatment interventions including use of radiographic study and dispositions. mTBI defined as arrival GCS 15, possible loss of consciousness (LOC) and no other injury. Institutional Review Board (IRB) approval and data analysis was obtained and performed.
Results/Effects
Over 10 years, the study found rapid rise in past 5 year with number of concussions which increased by 140% compared to ED patient census and trauma patients volume increased only by 23.9%; p< 0.02. (Figure 1). There were also increases in use of computer tomography (CT) for concussion by 25.8% with less than 1.2% of mTBI patients having a positive finding on head CT and none requiring neurosurgical intervention. Patient in hospital admits rose at the same rate as new concussions. Despite rise in mTBI and neurosurgical admits, there was no rise in neurosurgical operative cases.
Conclusions/Limitations
There has been an effective impact on mTBI presentation and admission to our ED and trauma centers in the past five years. CT increased in use with no improved treatment intervention. Future studies will need to determine utility of admit compared to outpatient observation and neuropsychiatric intervention

Introduction/Rationale
Children with traumatic brain injury (TBI) show increased rates of attention problems which may result in poor academic and social functioning. While numerous studies have examined the effects of cognitive rehabilitation programs addressing attention difficulties in adults, few have examined feasibility and efficacy of these interventions with adolescents, particularly adolescents with TBI-related attention problems. The few pediatric studies examining direct attention training in children with TBI have reported positive findings. The aim of this study was to examine the efficacy and feasibility of an adaption of the Attention Process Training Program (Sohlberg's Attention Information Management Program, AIM) for adolescents with TBI-related attention difficulties.
Method/Approach
A small trial of AIM was conducted with adolescents (13-17 years old) with attention difficulties post TBI. Participants completed computer-based attention exercises that were tailored to their attention difficulties, and identified and practiced meta-cognitive strategies to facilitate generalization. Weekly, adolescents had 10-15 individual computer-based sessions with a trained therapist and were instructed to engage in 3-4 in-home practice sessions. Attention was assessed pre- and post-intervention with a neuropsychological test battery as well as parent and adolescent ratings of attention and executive functioning. Feasibility and satisfaction were also assessed with a semi-structured interview following the intervention.
Results/Effects
Pre-post data from parent and self report measures (i.e., the Behavior Rating Inventory of Executive Functioning, Conner's Parent Rating Scale, Vanderbilt ADHD Parent Rating Scales), as well as results from a neuropsychological battery, which included select attention and executive functioning subtests from measures such as the Test of Everyday Attention, Delis-Kaplan Executive Functioning System, and the Peabody Picture Vocabulary Test, will be presented. In addition, feasibility data, and parent and adolescent satisfaction ratings will be presented.
Conclusions/Limitations
Cognitive rehabilitation interventions targeting attention difficulties following pediatric TBI may be a useful in reducing attention difficulties and associated academic and social challenges. This study reports on the effects of the AIM on parent and self-report measures of behavior and neurological functioning. Results from this pilot study will be used to guide a larger study utilizing this intervention with pediatric TBI samples.

1Physical Medicine and Rehabilitation, Emory School of Medicine, Atlanta, GA, USA, 2Division of Rehabilitation Services, Children's Healthcare of Atlanta, Atlanta, GA, USA
Introduction/Rationale
To examine upper limb motor coordination via quantitative and clinical sensory-motor measures in children with traumatic brain injury (TBI) in order to determine unobserved motor deficits compared to upper limb coordination of age-matched typically developing peers and to understand the relationship between upper limb coordination and behavioral, language, and executive function deficits between these two groups. Thus, testing the hypothesis that children with TBI who appear to have achieved physical recovery will demonstrate motor impairment compared to typically developing peers and the relationship between motor skills and cognitive skills in both groups.
Method/Approach
Ten children (7-13 yrs) post-TBI without observable physical deficits and ten typically developing children participated. Motor coordination measures included upper extremity sEMG of five muscles, the Jebsen-Taylor Test of Hand Function, the Nine-Hole Peg Test and the Semmes-Weinstein Test of Tactile Discrimination. Cognitive and language measures included the Comprehensive Trail-Making Test, Wisconsin Card Sorting Test and K-Bit, following directions, word fluency and story retell. Motor and cognitive outcomes were determined within and between groups using paired t-tests. Correlations were calculated to determine the relation between motor and cognitive/language measures within each group.
Results/Effects
There was a significant difference in fine motor performance between groups in both the dominant and non-dominant hands as measured by the Nine-Hole Peg test. Statistically significant differences were also noted between groups in overall intellectual functioning, story retell, and verbal fluency. In addition, a strong relationship was noted between fine motor performance and cognitive measures.
Conclusions/Limitations
Findings from this investigation reveal differences in fine motor performance even in children without visible signs of motor deficits. Emphasis following TBI in children often focuses on cognitive, behavioral, and language deficits both in rehabilitation and school special education programs. Undetected sensory-motor deficits that are not immediately apparent may be overlooked and subsequently not adequately addressed. Improved understanding about children's fine motor functioning and the relationship to their cognitive skills and learning will facilitate comprehensive interventions following TBI.

Violeta Nestorov2
1Faculty of Special Education and Rehabilitation University of Belgrade, Belgrade, Serbia, 2PU Savski Venac, Belgrade, Serbia
Introduction/Rationale
The objective of our research was to investigate the presence of dysgraphia in Gypsy children of younger school age and study the relation of semilingualism present in these children with the appearance of dysgraphic handwriting. According to Golubovic S. (1998, 2000, 2006, 2011), dysgraphia is a disorder in writing, or acquiring the ability to write, in spite of the existence of normal intelligence, good sight and hearing, proper education and social conditions.
Method/Approach
The research was performed on a sample of 79 examinees, pupils from the first and second grade of elementary school, divided into an experimental (42 examinees) and control group (37 examinees). The experimental group consisted of pupils of Gypsy nationality, whose families speak Gypsy and Serbian (semilingualists). Testing the handwriting ability was conducted using the Test for assessment of dysgraphic handwriting. The test is a modified version of the scale for assessment of dysgraphia designed by the French authors Ozias and Ajuriaguerra. The scale was translated and modified for the Serbian-speaking area (Dordic and Bojanin, 1997).
Results/Effects
The harmoniously developed handwriting was present in 19.9% examinees of the experimental group, the ugly handwriting was present in 28.6% examinees, dysgraphic handwriting in 26.2% and extremely dysgraphic handwriting was present in 26.2% of the experimental group examinees. With the control group examinees the harmoniously developed handwriting was present in 62.2%, ugly handwriting in 24.3%, dysgraphic handwriting in 10.8% and extremely dysgraphic handwriting with 2.7% of the control group examinees.
Conclusions/Limitations
The frequency of experimental group examinees was significantly greater in the dysgrahic and extremely dysgraphic handwriting, and significantly smaller in the category of harmonious handwriting than in the examinees of the control group. Semilingualism has a negative impact on the course of language development of Gypsy children, reflected in their poorer cognitive performance, emotional development and poorer social position and making the civil emancipation of this ethnic community more difficult.

Attention Training as a Component of Balance Integration in Clients with mTBI and PCS
Rebecca Askew
Laura Coca
Suzanne Carr
Scripps Memorial Hospital Encinitas, San Diego, CA, USA
Introduction/Rationale
Media attention surrounding concussion and mTBI and the potential sequelae involved in immediate and long term care is on the forefront of the news and professional journals today. Recent literature shows a myriad of issues that can be experienced after concussion including problems with balance integration and cognitive impairments specific to attention. Scripps Encinitas Memorial Hospital in San Diego California is home to the CARF accredited Brain Injury Day Treatment Program.
Method/Approach
The team consists of Speech Therapy, Occupational Therapy, Physical Therapy, Neurology, Psychology and Social Services. All play an integral role in the recovery of our patient population. The Day Treatment team approaches each patient's care with an interdisciplinary perspective with team goals designed to address all of the components of their injury which may affect return to work and recreation. Attention deficits are a common impairment after brain injury and have been found to be effectively rehabilitated with specific interventions utilized by our speech therapists who specialize in cognitive therapy.
Results/Effects
Balance integration, especially with regards to the vestibular system, is a common impairment after injury and can be rehabilitated by Physical Therapists with specific and graded treatment programs. The ability to divide attention is a key component in dynamic balance skills and is necessary for safe and independent community re-integration. Working together, a treatment team can provide opportunities to both recover and implement normalized balance and attention into daily activities in a graded, organized and methodical way.
Conclusions/Limitations
In practice, the team combines individualized efforts that are impairment specific, progress the training to combine therapies, and then progress from a predictable to a dynamic environment in the community at large. The team's intention is to provide treatment ideas specific to attention and balance that will compliment the recovery process for patients who have sustained brain injury resulting in post-concussion syndrome (PCS) or mTBI.

Chiropractic Cranial Treatment Protocol Increases Successful Outcome of the Multidisciplinary Care Model for Traumatic Brain Injury (TBI) Patients: A case series.
Esther Remeta2
Charles Blum1
1Sacro Occipital Technique Organization - USA, Sparta, NC, USA, 2Chiropractic Research Institute, Advance, NC, USA
Introduction/Rationale
This article shares a novel manner of multidisciplinary care for traumatic brain injury (TBI) incorporating allopathy, chiropractic, psychology, acupuncture, neurorehabilitation, and nutrition.
A 28-year-old female suffered a TBI from a violent attack resulting with severe headaches requiring daily bed-rest for two-years.
A 30-year-old female sustained a TBI from a motor vehicle accident resulting in decreased bilateral occipital lobe metabolic activity, chronic headaches with transient paralysis of her left extremities and short-term memory loss.
A 70-year-old male suffered a TBI from a stroke causing paralysis of the right upper and lower extremity, swallowing difficulties and speech problems.
Method/Approach
A focal point of the multidisciplinary care at this clinic is Sacro Occipital Technique (SOT) cranial manipulation protocols, along with specific neurological rehabilitation training and home exercises. Home therapy focuses on physical, mental and emotional balance which increases efficacy of treatment. The care model is implemented for a minimum of 1-year with most patients remaining in the model for 5-years.
Results/Effects
The 28-year-old female showed significant improvement with a gradual increase in function and headaches occurring only once every 2-weeks, tapered off all her prescription medications while under medical supervision, and now lives a more normal life with her young 8-year-old daughter taking part in her life activities as well.
The 30-year-old female, after 5-years of treatment (1-time per week), is headache free, has neither short-term memory loss, nor any paralysis episodes.
The 70-year-old male, after 9-months of care, returned to work full-time, without paralysis, speech or swallowing problems with no obvious deficits despite left parietal lobe infarct per magnetic resonance imaging (MRI).
Conclusions/Limitations
Success was measured based on improved quality of life and return to activities of daily living with decreased pain and improved function. Highest success was achieved with the 5-year model and with the inclusion of SOT cranial manipulation protocols. The temporal nature of the patient's response to care and their gradual worsening of symptoms prior to treatment at this clinic suggest the patient's conditions would have worsened. This care model gives greater hope for those suffering from TBI as well as gives the health care profession at large more options to create treatment plans resulting in better prognosis.

Jana Downum1
Hanli Liu2
Patrick Plenger1
1Pate Rehabilitation, Dallas, TX, USA, 2University of Texas at Arlington, Arlington, TX, USA
Introduction/Rationale
Following traumatic brain injury (TBI) individuals frequently experience heightened distractibility along with other cognitive impairments. This vulnerability to environmental distractions significantly limits performance on many activities and is often the specific focus of rehabilitation. The current study used functional Near-Infrared Spectroscopy (fNIRS) to investigate different patterns of cortical activation associated with distractibility following TBI in order to uncover possible patterns that may lead to improvements in treatments.
Method/Approach
Sixteen patients undergoing post-acute rehabilitation following TBI and 14 controls underwent three consecutive sessions during which fNIRS measures were taken while they performed a modified Stroop task. The Stroop task consisted of a simple condition (naming the color of a dot) and a more complex condition (naming the color of ink of a color word). Each condition was presented three times in a quasi counterbalanced order. A Hitachi ETG-4000 fNIRS optical system was employed, using a 3 x 11 optode array covering the forehead and anterior bi-temporal regions.
Results/Effects
Activation patterns associated with the complex condition minus the simple condition and both conditions contrasted with baseline were analyzed using NIRS-SPM. Control group images for each analysis showed significant activity (p = 0.05) in the frontopolar cortex which decreased with each session. Patient activity showed the reverse trend with significant activity noted during both the simple and complex conditions for the first session. However, employing the subtraction method yielded no activity since activation patterns and significance were essentially the same for both the simple and complex conditions.
Conclusions/Limitations
Decreased frontal activity across sessions may be due to practice and increased automatization for controls. Widespread frontal activity, may be associated with heightened distractibility and indicate that the patients may be having difficulty selectively attending to specific task demands. While it is possible that fNIRS may assist in measuring susceptibility to distraction in individuals following TBI, further investigation using a wider array of tasks may be necessary. Moreover, it will be important to determine whether noting patterns of widespread frontal activation is superior to behavioral measures of distractibility.

Cerebral Curvularia Fungi Presenting in an Immunocompetent Patient: A Case Report.
Sandia Padavan
Brian Greenwald
Mount Sinai School of Medicine, New York, USA
Introduction/Rationale
Fungal Infections continue to be a serious threat to immunocompromised patients. The clinical presentation is often variable, without any diagnostic characteristics, often leading to an inaccurate initial diagnosis. Curvularia infections of the central nervous system are extremely rare and can present in immunocompetent patients. This case increases awareness of this rare condition. It is important for clinicians to be aware of the presentation and potential fatality of this condition for early diagnosis and intervention.
Method/Approach
33 year old male with no significant past medical history presented to the emergency department (ED) with a chief complaint of progressive unsteady gait, right sided occipital headaches, dysphonia, anorexia resulting in 20 lb weight loss, diplopia, shortness of breath, and decreased sensation on the right side of his body for two weeks. Physical examination was unremarkable. A computed tomography (CT) scan of the head revealed a right-sided intramedullary mass. A CT scan of the chest, abdomen, and pelvis was ordered due to concern for metastases, which showed a consolidative opacity within the left lower lobe. His admitting diagnosis was cerebral tumor.
Results/Effects
Medical management included a right craniotomy for resection of the mass and fine needle aspiration (FNA) of the left lower lobe lung mass. The results of the FNA biopsy favored a necrotizing granulomatous process. The surgical pathology of the cerebral mass demonstrated septate hyphae consistent with Curvularia. Although he had no significant past medical history, his social history was significant for daily marijuana use and employment as a carpenter. Aggressive medical management and rehabilitation from this rare and devastating infection was required.
Conclusions/Limitations
The literature has only a few documented cases of cerebral Curvularia, most of which have been fatal. The presentation of such patients consists of several symptoms, which develop quickly, making an early diagnosis difficult. In this case, the potential sources of Curvularia include marijuana and wood. Treatment standards for Curvularia have yet to be standardized and the progressive symptoms, therefore, in this case illustrate the need for clinicians to be aware of symptoms that can present as a variety of possible diagnoses and note the potential sources of infection by obtaining a thorough social history.

Introduction/Rationale
The purpose of this study was to identify the factors associated with odds of mortality and life expectancy after traumatic brain injury (TBI). Specifically, the focus was on the effects of demographic, etiology, discharge disability, and socio-environmental factors.
Method/Approach
Participants were adults (18 years or older) who sustained a TBI July, 2001 to December, 2009 and were alive 1-year post-injury. Identification was through the TBI Model Systems National Database, a network of institutions providing specialty care in the United States. Mortality was identified using the Social Security Death Index. Person-year logistic regression analysis was used to identify the odds of mortality. There were 5,806 1-year survivors with 19,683 person-years and 362 deaths.
Results/Effects
Among 1-year survivors, fall and violent etiologies, male gender, white race, and higher age were significantly associated with greater odds of mortality. Persons not independent in feeding at rehabilitation discharge were at increased odds of mortality; however, unconsciousness and ability to walk at rehabilitation discharge were not predictive of mortality. Among the socio-environmental predictors, higher personal income was protective of mortality. Pre-injury education and marital status were not significantly related with mortality.
Conclusions/Limitations
Socio-environmental factors, specifically income, at TBI onset appear to be highly related to post-TBI mortality, even after accounting for demographic status and multiple other factors. Future studies are needed that provide updated socio-environmental information (not just that available at rehabilitation) to assess the effect of change in socio-environmental status. Additionally, behavioral variables should be investigated as they are potentially modifiable factors.

Chiropractic Sacro Occipital Technique (SOT) and Cranial Treatment Model for Traumatic Brain Injury Along with Monitoring and Supplementing for Neurotransmitter Balance: A Case Report.
Esther Remeta2
Charles Blum1
1Sacro Occipital Technique Organization - USA, Sparta, NC, USA, 2Chiropractic Research Institute, Advance, NC, USA
Introduction/Rationale
The purpose of this paper is to present a novel treatment model incorporating laboratory testing to evaluate neurotransmitter balance and chiropractic cranial care for the treatment of a patient with traumatic brain injury (TBI). A 33-year-old female presented at this office for care secondary to an attack that included strangulation and repeated facial trauma. Her main symptom was chronic debilitating headaches unresponsive to rest, medication, or other interventions. Prior to being seen at this office she was under the care of a neurologist and taking medications, which caused her extreme side-effects, yet did not relieve her headaches.
Method/Approach
She has been under care for three years, which consisted of chiropractic sacro occipital technique (SOT) and cranial treatment. Within the past year laboratory tests were instituted to monitor neurotransmitter balance of the HPA axis and used to help direct nutritional supplementation. The patient was seen once per week for chiropractic care and laboratory tests, while usually performed every 4 months, in this case was performed annually. This was due to the patient not performing the laboratory tests in a timely manner, believed due to her profile, which included inability to cognitively function in scheduling situations.
Results/Effects
Overall all of her symptoms improved which included headaches, which are less frequent, and less debilitating. The headaches went from being daily constant, and chronic to 2-3 times per week with significantly less intensity and debilitation, allowing her to function in her activities of daily living. Prior to care, she could not function when she had a headache. While she was making good progress with the chiropractic care during the 1st two-years, when nutritional supplementation based on laboratory analysis for neurotransmitter balance was instituted, headaches and function improved, including better sleep patterns and mental clarity.
Conclusions/Limitations
Treatment of brain trauma is a very individualized process and what may help one patient may not help another. It is unclear with case reports whether effective treatment for one patient can be generalized to the brain trauma population at large. However, it is worthy of consideration when a patient does not respond, or has an adverse reaction to medications and is non-responsive to traditional approaches, that a chiropractor trained in SOT and cranial treatments might be considered for collaborative care. Greater research is needed in interdisciplinary settings to determine how this subset of patients may be best served.

Dynamic Postural Instability in OEF/OIF Veterans with Mild TBI and Disequilibrium
Mark Walker
Tao Pan
Ke Liao
Case Western Reserve University and Cleveland VAMC, Cleveland, OH, USA
Introduction/Rationale
Dizziness and imbalance are common symptoms in acute concussion and are also seen frequently in the post-concussive syndrome after both blunt and blast trauma. There are several forms of post-concussive dizziness, including positional vertigo, migraine-related dizziness, and subjective imbalance. The latter is the least understood and is often not easy to recognize clinically. The goal of this study is to quantify dynamic postural stability in veterans of Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF), with a history of combat-related mild traumatic brain injury (mTBI), who report persistent disequilibrium.
Method/Approach
9 OEF/OIF veterans with mTBI and persistent disequilibrium and 10 subjects with no history of mTBI were studied. Subjects were perturbed abruptly by a rope attached to a waist-level belt and pulled by a computer-controlled linear actuator, in two directions (forward and to the side), and with eyes open and closed. We recorded body kinematics using an infrared motion tracking system with reflective markers on the head trunk and legs. The length of the two-dimensional (2D) sway path was calculated over the first three seconds after the onset of each perturbation.
Results/Effects
Sway paths (measured at the sacrum) were much longer for the mTBI group with disequilibrium (median 38.1 cm) than for the non-TBI group (median 16.9 cm). Using a repeated-measures ANOVA analysis, it was found that sway path lengths were significantly longer for mTBI vs non-mTBI (p<0.05), for eyes closed vs. eyes open (p<0.03), but not for the direction of the pull.
Conclusions/Limitations
Dynamic postural stability is impaired in OEF/OIF veterans with persistent disequilibrium following mTBI. Although these deficits may be relatively mild and are typically not apparent during routine clinical examination, they could have a critical impact on balance in unfamiliar and physically challenging environments, such as during combat.

Posttraumatic Stress Disorder following an Offshore Explosion
Lawrence Dilks1
Burton Ashworth2
Jackie Bourassa3
Billie Myers2
1Counseling Services, LA, USA, 2Fielding Graduate University, CA, USA, 3McNeese State University, LA, USA
Introduction/Rationale
The purpose of this study was to explore the posttraumatic stress disorder (PTSD) symptomatology in individuals who experienced an explosion on an offshore rig. According to the Diagnostic and Statistical Manual-IV-TR for an individual to have PTSD they must have: (1) experienced or witnessed a traumatic event; and/or (2) experienced intense fear, or horror. If at least one of those criteria is met, they must also meet the following criteria: (1) intrusive recollection; (2) avoidance; (3) hyper-arousal. The study attempted to answer the question: What trauma-related symptoms were present following the explosion that were not present prior to the explosion?
Method/Approach
This case study included four participants between the ages of 22 and 29 (M = 26). Each of the participants received a complete neuropsychological evaluation by a psychologist. Among the four participants, one participant had obtained a pre-morbid head injury and a medical diagnosis. No participants had a remarkable history.
Results/Effects
The results showed that all of the participants had PTSD and three of them also had a post-concussion. The symptoms they reported were intrusive thoughts, flashbacks, avoidance behaviors, nightmares, hyper-vigilance, anxiety, and fear. Among the four participants, two of them also reported jumpiness, fear of being lost, and guilt. Each of them provided an initial trauma narrative that contained similar descriptions of events with vivid recollections.
Conclusions/Limitations
Based on the results of the study, individuals exposed to an explosion experience many trauma-related symptoms that meet criteria for PTSD. Although it cannot be concluded that all individuals exposed to this environmental disasters were negatively affected, it can be concluded that these individuals suffered similar trauma-related symptoms and provided similar, vivid trauma narratives.

Introduction/Rationale
Students spend approximately 30% of their waking hours in school, providing both a natural and appropriate environment for psychosocial rehabilitation. This is especially important given that student's socio-emotional, behavioural, and scholastic outcomes after sustaining an acquired brain injury (ABI) are incredibly variable and independent of injury severity. Within the province of Ontario, ABI is not a recognized exceptionality within the school system, which impacts the student's ability to access the multitude of resources often required post-ABI. This province and Centre-wide research project serves to examine student-, parental-, teacher-, and school policy-based variables that influence students' successful reintegration within the school system.
Method/Approach
Students between the ages of 6 - 18 years, who are 1 - 5 years post-injury, were identified by health care providers and approached to consider participation in the study along with their respective parents. Their teachers and principals were approached with permission of the students and their respective school boards. Participants completed status-appropriate standardized and non-standardized measures (i.e., students were assessed with psycho-educational and neuropsychological tests and self-report measures; parents, teachers and principals completed questionnaires related to history, status, ABI knowledge, school policy, and the student). Regression analyses were conducted to identify variables that best predicted successful reintegration.
Results/Effects
The schools' policies and procedures (i.e., early intervention, philosophies of student inclusions, structured programming, and community reintegration, etc.), in addition to cognitive indices of injury severity (i.e., neuropsychological competency), best predicted the student's academic success, as well as their behavioural and social reintegration within the classroom setting. As expected, acute measures of physical injury severity (i.e., GCS, LOC, PTA and PCS) were not predictive of outcome. Modifiable variables, such as educator awareness and knowledge of ABI, particularly within schools that promote policies and procedures of inclusion, were predictive of successful social, behavioural and scholastic reintegration, over and above neuropsychological competency.
Conclusions/Limitations
These findings identify important 'modifiable' variables within the school system that can mediate the successful academic and social reintegration of students after an ABI. Improved educator knowledge and awareness and the promotion of early intervention and student inclusion policy are variables that can be changed, and are independent of the student's less-malleable injury. The results provide considerable rationale for the incorporation of these variables into 'best practice' guidelines for the province of Ontario and school systems elsewhere.

ABI Identification in Combination with Educator Knowledge Promotes Social and Academic Success in Students with ABI
Kathy Wlodarczyk
Dawn Good
Sheila Bennett
Brock University, St. Catharines, Canada
Introduction/Rationale
Returning to school is a primary goal for students who have sustained an acquired brain injury (ABI). A supportive school environment is instrumental in recovery and facilitates transitioning back to school. Since ABI is not a recognized exceptionality in Ontario, teacher knowledge and awareness of the learning needs associated with injury is variable. Since educators are readily available to implement remedial strategies to foster learning and development, examining the knowledge base and understanding these educators have of the challenges and performance skills associated with ABI is critical to student achievement, both academic and social.
Method/Approach
This research consists of data that is derived from a larger collaborative project (Good et al., 2012), which includes students from Ontario, Canada who are between the ages of 8 and 18 years of age who have experienced a moderate to severe ABI and have returned to the classroom environment. The relationship between teachers' subjective ratings of their students' academic performance and social competence is compared to measures of the students' capacity using standardized neuropsychological and self-report assessments. Discrepancies as a function, teacher knowledge of ABI, and its associated learning needs are also examined.
Results/Effects
As expected, educator ratings of competencies were not predictive of standardized measures of student ability. Additionally, teacher knowledge influenced student success. Students with ABI who had no individual education plan (IEP), but who were in a classroom with a teacher knowledgeable about ABI, performed well in academic and social domains. Conversely, students who had an IEP, but were in a classroom with an educator who lacked knowledge of the learning needs associated with ABI and/or had knowledge specialized for other special needs, were disadvantaged.
Conclusions/Limitations
Having a teacher who is informed about the learning challenges associated with ABI is beneficial for academic achievement and social inclusion. More inclusive friendships and school relations are sustained and accompanied by lessened emotional and personal adjustments when educators are knowledgeable about ABI. Formal recognition of ABI as an exceptionality in the Ontario school system would increase the likelihood that coverage of ABI would be mandatory in the teacher education curriculum - facilitating the teachers' awareness of the learning needs of these students and ultimately improving their school experience, and success.

The Influence of Emotionally-arousing Stimuli on Decision-making in University Students with Self-reported Mild Head Injury
Sean Robb
Dawn Good
Brock University, St. Catharines, Canada
Introduction/Rationale
Mild head injuries (MHI) account for approximately 90% of all head injuries and routinely involve ventromedial prefrontal cortical (VMPFC) alteration, due to this area's vulnerability to biomechanical injury. Individuals with an MHI illustrate reduced physiological arousal prior to making a decision, and in more severe brain injuries, demonstrate impairment in social decision-making. This study examines decision-making processes in competent university students with and without a MHI as a means to explore the degree to which mild injuries mirror those of more traumatic brain injuries (TBI), and whether music can elevate participant's physiological arousal and alter decision-making processes.
Method/Approach
This quasi-experimental study randomly assigned university students to one of three conditions of background noise (positive, negative valence classical music and pink noise), while examining an example of social decision-making using the Iowa Gambling Task (IGT) - a task that mimics the uncertainty associated with gambling using card selections from four decks of various risk levels (advantageous to disadvantageous in terms of point gains versus losses). This was followed by administration of Maia and McClelland's (2004) questionnaire to assess the degree of explicit strategizing participants could report after completing the task.
Results/Effects
Individuals reporting a history of MHI were physiologically underaroused, relative to their no-MHI cohort, prior to making card selections and illustrated more disadvantageous selections overall (i.e., slower transition from disadvantageous to advantageous choices leading to less gain; quicker return to disadvantageous decisions after being punished). Negatively-valenced music amplified arousal and resulted in improved decision-making in individuals with MHI. This occurred despite the groups reporting using similar strategies related to their selections from the four decks. Explicit knowledge as illustrated by the subjects' estimate of overall net gains and choice selection, was dissociated from actual outcomes and implicit indices of awareness.
Conclusions/Limitations
Decision-making can be influenced as a function of induced arousal, even in persons with mild forms of head injury. Individuals who report having a MHI are less reactive to uncertainty and negative outcomes (at least in a gambling task) and, thereby, may be more inclined to make riskier choices which, in turn, can lead to more adverse outcomes. This has implications for social decision-making (i.e., interpersonal, financial, etc.). Conditions that elevate arousal may improve sensitivity to consequences, resulting in improved decision-making. These changes occur despite explicit knowledge, and illustrate the importance of implicit somatic markers in decision-making processes.

Emotional Underarousal in University Students with Self-reported Mild Head Injury
Julie Baker
Dawn Good
Brock University, St. Catharines, Canada
Introduction/Rationale
Previous studies from our lab (e.g., Baker & Good, 2010) have demonstrated that university students with self-reported mild head injury (MHI) present with flattened affect are physiologically underaroused (as indexed by reduced electrodermal activation [EDA]), and are less responsive to stressors in their environment despite increased reports of experiential life stressors-relative to their no-MHI cohort. This profile of underarousal is mirrored in the moderate-to-severe traumatic brain injury (TBI) population, particularly those with ventromedial prefrontal cortex (VMPFC) disruption (e.g., Tranel & Damasio, 1994). The current study further examined emotional responsiveness as a function with a history of head trauma.
Method/Approach
University students with and without a history of MHI (N = 80) viewed emotionally evocative stimuli (positive, negative, or ambiguous) selected from the International Affective Picture System (IAPS; Lang et al., 2008). Participants rated the valence, arousal, and intensity of the stimuli. Emotional arousal responses (i.e., EDA and heart rate) were recorded (via Polygraph Professional Suite, 2008) throughout the session. Participants also completed indices of emotional functioning (e.g., BarOn Emotional Quotient Inventory [EQ-i] Baron, 1997; State Trait Anxiety Inventory [STAI], Spielberger, 1983) and self-reported MHI history (i.e., sustained an "altered state of consciousness" from head trauma; post- concussion syndrome (PCS) reports).
Results/Effects
Results replicate earlier findings that despite increased reports of experiential life stressors, students with self-reported MHI were emotionally underaroused as compared to their no-MHI cohort. Further, students with a history of MHI demonstrated attenuated emotional arousal to emotionally-evocative stimuli (i.e., reduced EDA; emotional ratings of stimuli) relative to their no-MHI counterparts. Similarly, differential reports of emotional functioning (e.g., emotional intelligence [EQ-I, 1997]) and self- reported indices of emotional expression (i.e., dampened) were also evident as a function of history of MHI. Students with MHI were less emotionally reactive to experiences of emotional events.
Conclusions/Limitations
The emotional profile of persons with mild head trauma parallels the underaroused status of persons with moderate-to-severe disruption to the VMPFC, albeit more subtly, and may be indicative of non-transient effects of neural disruption. Emotions play an important role in guiding decision making and choice selection (see Damasio's somatic marker hypothesis, 1998). We suggest that emotional responding following self-reported MHI may impact their socioemotional interactions with others due to attenuated responses to emotional situations.

Empathic Differences In Individuals With Sub-clinical Psychopathy and Mild Head Injury
Tanvi Sharan

Brock University, St. Catharines, Canada
Introduction/Rationale
Understanding and responding to the emotional experiences of others are essential for successful social interaction. Empathic deficits have been noted in psychopathy, as well as in traumatic brain injury (TBI). While psychopathy has been associated with structural alteration in the Ventromedia Prefrontal Cortex (VMPFC) (emotional dysregulation), TBI involves more diffuse injury to the orbito-frontal cortex including VMPFC, Dorsolateral Prefrontal Cortex (DLPFC)(evaluative and rational cognition). In order to tease apart the differential mechanisms involved leading to similar challenges in social integration, the current study examined empathy in those high in subclinical psychopathy versus reporting a history of mild head injury.
Method/Approach
University students completed an emotional processing task designed to induce empathy. Participants were presented with a set of images (negative, neutral) and asked to rate their perceived empathy towards the scenario/individual depicted in each image (affective empathy). Following each trial, the same image was subsequently presented with accompanying context scenarios which provided either confirming, or contrasting, descriptions of the prevalent theme in the images. Empathy ratings following each contextual description were also collected. Participant's electro-dermal activity and pulse rate were monitored while they completed the task. The SRP-III and the PPI-R were used to assess level of psychopathy.
Results/Effects
Individuals high on psychopathy produced lower empathy ratings relative to those low on psychopathy. Similarly, the mild head injury (MHI) group showed reduced affective empathy relative to the non-MHI group. An interaction between personality and head injury emerged such that MHI individuals high on psychopathy produced the most differential responding with respect to empathy ratings. They reported less empathy for negative images (affective empathy) comparable to the MHI low psychopathy group, and also produced the greatest influence of the cognitive manipulation (i.e., change in ratings) after reading the altered context, comparable to the NMHI high psychopathy group.
Conclusions/Limitations
Current findings implicate the involvement of different mechanisms in the manifestation of empathic deficits observed in two distinct populations namely, psychopathy and TBI. While empathic deficits observed in the higher psychopathy group were primarily affective (implicating possible dysfunction in the VMPFC), individuals reporting a history of head injury showed reduced affective and cognitive empathy (implicating possible VMPFC and DLPFC involvement). Further, affective empathy was further reduced in the MHI group scoring higher on psychopathy. This finding was ameliorated by their cognitive empathy showing a particular sensitivity to contextual cues which can guide assessment of emotional situations.

A Theoretical Model for Outcome Prediction in Post-Acute TBI Rehabilitation
Kier Bison
Sid Dickson
Devin Qualls
Pate Rehabilitation, Dallas, TX, USA
Introduction/Rationale
Using data collected over 13 years, traumatic brain injury (TBI) patients' are assessed by the treatment team bi-weekly on the outcome measure PERPOS. This tracking system assists with treatment planning, forecasting length of stay, and justifying post acute treatment to payors. PERPOS is an ecologically validated measure that assesses level of ability/impairment within the complexity of environmental factors (distraction and structure).
Method/Approach
1,423 TBI patients consecutively admitted to a comprehensive post acute brain injury rehabilitation program were analyzed for this theoretical model. Patients were grouped by PERPOS scores assessed at admission. For each impairment level, mean patient progress was tracked and divided into progress quartiles.
Results/Effects
New patients have been compared to these normative data collected over 13 years. The treatment team can easily track how the individual patient is progressing through their post-acute TBI rehabilitation.
Conclusions/Limitations
Therapy teams plan future treatment strategies based on how the individual patient is progressing. The progress can also be communicated to stakeholders. This study is limited to a TBI population. Future analyses will include 13 years of data on cerebrovascular accident (CVA) patients, as well as refining the predictive model for TBI patients.

Centers for Disease Control and Prevention, Atlanta, GA, USA
Introduction/Rationale
On April 27, 2011 multiple devastating tornados struck Alabama resulting in 247 deaths and over 1,500 reported injuries. This study examines injured tornado victims, treated in Alabama hospitals, to understand the burden of head injury and the potential benefit of head protection during tornados.
Method/Approach
The Alabama Department of Public Health and CDC performed a retrospective review of emergency department (ED) and inpatient records in 39 hospitals that treated one, or more, injured patients. Cases were defined as tornado victims >17 years of age seen April 27-30, 2011 with an International Classification of Diseases (ICD), 9th Revision injury code of 800.0-959.9. All ICD-9 codes were analyzed with ICDMAP-90 to classify injury region and severity. We conducted phone interviews with 98 (7%) of all abstracted cases and 200 uninjured community controls who responded to recruitment Public Service Announcements (PSAs), to understand personal and family helmet usage.
Results/Effects
After extremity injuries, head injury was the most frequent diagnosis, representing 425 (30.4%) of 1398 injured patients. Of these, 393 (92.5%) were minor with an Abbreviated Injury Score (AIS)<3, while 32 (7.5%) were severe, AIS>=3. Ten head injured patients (2.4%) died, representing 66.7% of 15 total hospitalized tornado deaths. Among the 298 phone interview respondents, there were no injured cases and eight uninjured controls reported using a helmet, though only 1 experienced home damage. Two case children (both with significant home damage) and 10 control children donned helmets. Of these twelve children, only 3 were injured.
Conclusions/Limitations
Most head injuries were minor, though head trauma constituted a significant proportion of total in hospital tornado deaths. Few cases took shelter in tornado safe rooms or storm shelters. Due to the high frequency of head injury, head protection should be stressed among persons unable to reach a tornado safe room or storm shelter.

Benefits of Implementing an Interdisciplinary Model of Care for Brain Injury in an Acute Inpatient Pediatric Rehabilitation Setting
Mark Pedrotty
UNM-HSC, Albuquerque, NM, USA
Introduction/Rationale
Acute inpatient Pediatric Rehabilitation for brain injury is complex and requires the services of a number of professionals. The use of an interdisciplinary treatment model provides unique benefits for the treatment team and the patient. This paper will provide a qualitative review of examples of interdisciplinary treatment and the benefits relative to multidisciplinary treatment.
Method/Approach
Several cases will be reviewed to discuss the essential elements of interdisciplinary care. Areas covered include management of noncompliance and acting out, depression, severe agitation and poor reality testing, family stress, development of insight and awareness, use of medication, cultural issues, and community reintegration.
Results/Effects
Interdisciplinary work allows for team members to develop behavioral interventions that can be applied across therapies, skill development that coordinates interventions, co-treatment strategies within therapy to apply consistent but different interventions simultaneously, and expression of feelings with team members related to treatment progress to help develop treatment goals; as well as including the family and patient directly in the development of integrated goals and interventions.
Conclusions/Limitations
Interdisciplinary work improves team flexibility and cohesiveness, including integration of family into care, and possibly improving the outcome. Development of an interdisciplinary team requires careful consideration of the administrative structure and staff qualities necessary to support it. More research is needed to provide best practices models that include interdisciplinary care.

Technology for Objective Diagnosis and Rehabilitation of Mild TBI
John Lloyd1,2
1James A Haley VA Hospital, Tampa, FL, USA, 2University of South Florida, Tampa, FL, USA
Introduction/Rationale
There are many potentially injurious events that can cause traumatic brain injury (TBI), including automobile and motorcycle accidents, blunt force trauma, sports and recreation impacts, as well as combat related events. The Centers for Disease Control (CDC) estimates that approximately 1.4 million US individuals sustain TBIs every year. Currently, the diagnosis of mild traumatic brain injury (mTBI) can only be made subjectively by assessing patients for loss of consciousness (LOC), altered consciousness, or posttraumatic amnesia. There is no objective medical device for diagnosing concussion/mTBI, nor for monitoring rehabilitation following brain trauma to determine when it is safe to return to pre-injury activities.
Method/Approach
During the 2011/12 football season, researchers studied head impacts among 20 members of a high-school varsity football team when one of the players experienced a significant head impact that was later clinically confirmed to be a concussion. Head impact data (dose) was acquired using the Simbex HITS system, while brain activity (response) was recorded using a 16-channel wireless Nicolet EEG system.
Results/Effects
It was discovered that certain EEG signals are particularly sensitive for identifying changes in brain activity resulting from the insult of physical head trauma. Power-spectrum analysis using Matlab has lead to the development of an algorithm which clearly delineates concussive/TBI, where the magnitude of change in brain activity is directly proportional to the severity of the head impact.
Conclusions/Limitations
The research demonstrates a real-time objective method for diagnosis of clinical concussion/mTBI. Logistically, it may not possible for personnel to be monitored in real time. By using a simplified method during the acute post-injury phase, however, it will also be possible to objectively diagnose a clinical concussion/mTBI. The most exciting implication of the technology is the potential to monitor brain activity during rehabilitation to determine when it is safe to return to pre-injury activities.

The Effect of Brain Training on Cognitive Assessment: A Pilot Investigation
Douglas Mann
Victor L. Szwanki
Jay J. Mistry
Rowan University, Glassboro, NJ, USA
Introduction/Rationale
Research exists supporting the role of brain training increasing memory in patients suffering from brain pathologies such as dementia and Alzheimer's. Little research exists on the role of brain training increasing memory in patients who have suffered one or more concussions. The loss of memory is considered a primary symptom of concussion. One of the tools utilized to measure verbal and visual memory following a concussion is the cognitive assessment test IMPACT. This pilot investigation was done to determine if brain training can increase IMPACT scores on individuals with lower than normative data in the areas of verbal/visual memory.
Method/Approach
This investigation was done in a research laboratory and involved subjects utilizing an online brain training program. The cognitive assessment test IMPACT was utilized to measure baseline visual/verbal memory. Subjects were placed in a five week brain training program or a control group that received no cognitive training. Subjects were re-tested on IMPACT following a five week period. A total of 10 Division III athletes volunteered. Subjects were randomly placed in a group that did online brain training (N = 5) for 15 minutes a day 3x per week or a control group that did not participate. Training done through Fitbrains.
Results/Effects
The composite mean on verbal memory for the experimental group was 36.2, compared to 29.2 in the control group. The composite mean on visual memory for the experimental group was 36.0, compared to 3.60 for the control group. No significant difference was found in verbal memory (p = .76), and on visual memory (p = .15), between the experimental and control groups. Although the mean difference between the experimental and control groups was substantial, no significant differences were found due to small sample size.
Conclusions/Limitations
The effect of brain training on cognitive ability is worth further investigation with a larger sample size. In addition, further investigation on the role of cognitive training and concussion prevention and treatment should be examined.

North Dakota State University, Fargo, ND, USA
Introduction/Rationale
The purpose of the study presented here was to examine how behavior of soft tissues, such as the brainstem, can be predicted. The study examined the porcine brainstem under stress relaxation tests to characterize its mechanical properties and behavior.
Method/Approach
Under loading, and undergoing small deformation, the brainstem tissue behavior was simulated by Prony interpolations. The parameters of these models were extracted and examined to show their suitability and accuracies in comparison with the experimental data for the same tissue. In this regard, a sudden displacement ramp, as a stress relaxation, was applied to the brainstem to determine the time-dependent behavior of the tissue. The data was fitted optimally to extract the parameters of each model.
Results/Effects
Two and three term Prony series can be fitted to the experimental data for modeling purposes and the coefficient parameters can be similarly found through an optimization procedure. The results showed that two and three terms of the Prony series illustrated a close resemblance to the brainstem response. Based on the two-term Prony series, short-and long-term moduli of the same were derived as 7.88 and 1.87 kPa; and based on three-term Prony series, there were 7.92 and 1.74 kPa, respectively. The moduli were close to each other for both models.
Conclusions/Limitations
Both models of the Prony series can follow the behavior of the tissue, but a three-term Prony series follows the response of the sample more precisely. This indicates that the higher the number of terms, the more accurate the simulation becomes. The relaxation moduli, as well as the short- and long-term moduli (as intrinsic mechanical properties), of the tissue were derived.

North Dakota State University, Fargo, ND, USA
Introduction/Rationale
Blast events are a major source of traumatic brain injuries (TBIs). In recent years, computational studies have been conducted on the effect combat helmets have against blasts. Even when a helmet is used a brain can be injured at some level in a blast situation. The efficiency of the helmet mostly depends on the types of materials of which it is made, as well as the padding. This paper presents the results of a computational study on the effect a helmet has in reducing the level of the severity of the brain injury.
Method/Approach
In this study, the helmet and head were modeled by Finite Elements (FEs). In order to model a realistic situation, the helmet was placed on a fidelity head-model that included the complete components of the skull and brain. Appropriate contact conditions between the head components were included. Arbitrary Langrangian Eulerian (ALE) and penalty methods were used to simulate detonation and media, as well as the interaction between media and the head model. KEVLAR was considered to be the material for the helmet. A helmeted head model and a non-helmeted model were subjected to the same blast situation for comparison.
Results/Effects
The results of the brain's intracranial pressure (ICP), and kinematical parameters of the brain motion, were determined for the different masses of detonation. The results showed the degree of injury to the brain. It was determined that wearing the combat helmet noticeably decreases the level of ICP in the brain. The peak positive ICP was around 0.36 MPa without a combat helmet and 0.006 MPa with a helmet.
Conclusions/Limitations
The efficiency of a helmet can be examined during blast situations. The results show that the degree of injury to the brain, when wearing a combat helmet, is decreased because the helmet reduces the load transfer to the brain.

Factors Influencing Post-Acute Brain Injury Rehabilitation Treatment Outcome
Nicholas Cioe
Southern Illinois University, Carbondale, IL, USA
Introduction/Rational
Brain injury has a tremendous effect on the United States. The medical system has a continuum of care available but many of these services are extremely expensive. Despite the effectiveness of residential post-acute brain injury rehabilitation (PABIR) resistance to provide adequate funding remains because of a dearth of randomized controlled trial (RCT) studies demonstrating effectiveness. Some research suggests observational trials are typically more representative of community samples and yield conclusions similar to RCT studies.
Method/Approach
This study uses a large multi-state naturalistic community-based sample of individuals who received residential PABIR. The purposes of this study were to (1) use logistic regression to identify a model that considered the relationships among the predictor variables to explain treatment outcome for individuals receiving residential PABIR and (2) better understand how self-awareness influences treatment outcome.
Results/Effects
The final model contained five independent variables (substance use at time of admit, functioning level at time of admit, change in awareness between discharge and admit, admit before or after 6 months post-injury, and length of stay in the program less than or greater than 2 months). The model was statistically significant, [chi]2 (5, N = 434) = 194.751, p < .001, accounting for 36.2% (Cox & Snell R square) to 61.3% (Nagelkerke R square) of the variance in success rate, and correctly classified 89.4% of cases.
Conclusions/Limitations
Four of the five predictor variables (current substance use, change in awareness, LOS 2 months and TPI 6 months) made statistically significant contributions to the model. The strongest predictor of successful treatment outcome was change in awareness recording an odds ratio of 29.9 indicating that individuals who improved in self-awareness by at least one level were almost 30 times more likely to be in the successful outcome group, controlling for other factors in the model. Participants were also more likely to be in the successful outcome group if they admitted within 6-months post-injury (5.5x) and stayed longer than 2-months (4.4x). Findings also suggest that active substance use at time of admission did not prevent people from being successful.
