Although it can be appealing to stick to approaches or methods that work well, there are times when doing so results in ignoring unique opportunities. When we began a discussion about this Special Issue focused on Vestibular Rehabilitation, we saw an opportunity to do something different. Some of the articles included in this Special Issue are "focused review" articles; a different type of article than that has been published in JNPT in the past but featured in some other medical journals. Rather than presenting an exhaustive review of the literature as might be expected from a typical "review" article, a focused review provides a focused look at a specific topic, the newest research findings in a particular field, and the thought process and progress along a particular line of investigation by a laboratory or a small group of laboratories. Also included in this Special Issue are pilot studies and descriptive studies, each of which present new data and the authors' interpretation about the meaning of the data. Our Guest Editors for this Special Issue were instrumental in recruiting experts involved in ongoing research in defined areas related to vestibular rehabilitation who were eager to share with JNPT readers their emerging data and current thoughts about their work. We owe a huge debt of thanks to our Guest Editors and authors for taking this plunge with us!

Because many of the researchers and clinical scholars who contributed to this Special Issue shared preliminary data and thoughts about their ongoing research, perspectives about progress in the respective content areas are provided, rather than definitive answers. We believe that all authors did an exemplary job by sharing their thoughts about the meaning and clinical relevance of their current findings and the important next steps in their focused research areas.

We believe that this Special Issue presents some unique opportunities for our readers. The contributing authors provided an "insider's view" that is rarely available to those outside of the research arena. Those engaged in research know well the many preliminary studies or efforts that may be necessary to pave the way to a larger or funded study and the challenge of designing and implementing feasible and clinically relevant studies. The articles published in this issue represent such examples and provide insight into how knowledge evolves over time. In addition, recently acquired data are reported for the first time in several of the articles in this issue.

Opportunities for new knowledge, new insights, and a new appreciation of the remarkable breadth of research currently ongoing in the field of vestibular rehabilitation-all of these await each reader in this Special Issue. We hope that you agree with us that trying something different, to complement what has worked well in the past, has resulted in some unique opportunities.
