As nurses, we spend a lot of time on our feet. This holds true not only for bedside nurses but also for nurse educators, nurse practitioners and
many, if not all, other nursing professionals. Our feet carry three times our body weight with each step. When you factor in the strenuous job duties required in nursing, i.e., lifting patients, lifting equipment, and running to a code blue, to name a few, we add significant weight load on our feet. Furthermore, most of our walking and weight bearing at work is on hard surfaces – hospital floors, hallways, and the concrete stairs present in most healthcare facilities, which provide a “sterile” environment but are unforgiving surfaces that do little to improve the shock absorption of our steps.
Plantar fasciitis is one of the most common causes of foot and heel pain in the United States. There are many risk factors associated with developing plantar fasciitis including having a body mass index over 27, having heel spurs, microtrauma (from running, inappropriate shoes, and prolonged running, walking, or standing on hard surfaces) and underlying structural deformities such as flat feet (pes planus), high arches (pes cavus), exaggerated pronation, or limited ankle dorsiflexion. Despite numerous risk factors, the condition is largely considered an overuse injury. While the precise etiology is not completely understood, it is thought to be due in part to microtrauma and inflammation from prolonged standing, walking, or running in conjunction with the contributing risk factors noted above. Other factors include poor fitting or poorly supportive shoes and a recent increase in weight-bearing activity (i.e., a new running or exercise program).
Nurses are at high risk for developing plantar fasciitis due to job responsibilities. The plantar fascia is composed of fibrous bands that insert at the heel (calcaneus) and connect to the toes (metatarsals). These bands provide support to the foot and in turn, bear the weight of the body with ambulation and any weight-bearing activity. The plantar fascia assists with shock absorption via the windlass mechanism; when the toes extend during weight-bearing, stretch tension is applied to the plantar fascia and the medial longitudinal arch height increases and maintains the arch, stabilizes the foot, and provides dynamic shock absorption. There is no elastic tissue in the plantar fascia, so all the work is performed via this tension mechanism.
Common clinical symptoms of plantar fasciitis include pain in the plantar aspect of the heel, pain that is worse with the first step in the morning or after a longer period of inactivity, and similar heel pain after long periods of weight bearing (such as the end of a 12-hour shift). Onset is typically precipitated by a recent increase in weight bearing (new exercise routine, etc.). On clinical exam, there is palpable tenderness along the plantar fascia, specifically, at the area of insertion at the calcaneus. The “windlass test” is also typically positive, (heel pain reproduced with passive dorsiflexion of toes). If you develop foot pain or heel pain, proper diagnosis is key.
Once diagnosed with plantar fasciitis, the cornerstones of therapy typically include conservative measures with a combination of stretching (both calf and plantar fascia), ice, rest, orthotics, strength exercises to stabilize the foot and ankle, and short-term non-steroidal anti-inflammatory drugs (NSAIDs). Physical therapy is also a recommended treatment. Let’s look at some of these treatment modalities.
Treatment
Home
- Rest (and avoidance of exacerbating activity)
- Ice
- Try freezing a plastic water bottle (~ 16oz); once frozen, roll under your foot to ice the entire plantar fascia.
- Short-term over-the-counter NSAIDS (for acute pain)
- Stretching
- Try rolling a tennis ball under the foot, massaging the plantar fascia.
- Perform stretches targeting the calf (gastrocnemius and soleus), hamstrings and achilles.
- Over-the-counter orthotics (targeting distributing rear foot pressure)
- Heel support (heel cushioning to assist in shock absorption); silicone heel cups
- Medial arch support inserts
- Properly fitting shoes (Read Shoe Shopping - Put your best foot forward!)
- Motion control shoes
- Consider rotating shoes if working multiple days in a row.
- Limit time walking barefoot or in flip-flops.
- Consider foot reflexology or massage by someone with experience treating plantar fasciitis.
Physical therapy
Typically includes:
- Proper assessment of foot posture and underlying structural deformities
- Manual therapy (massage, myofascial release) targeting mobilization of the plantar fascia, gastrocnemius and soleus myofascia, joint mobilization
- Stretching (calf, hamstring, posterior muscle groups)
- Anti-pronation taping
- Foot orthoses
- Night splints (maintains a static stretch during sleep)
Orthopedist or Podiatrist
Potential treatment modalities:
- Corticosteroid injection
- Casting or controlled ankle motion (CAM) walker (boot); both designed to prevent weight bearing on heel and promote rest
- Extracorporeal shockwave therapy (ESWT); improves neovascularization of the area of pain by inducing microtrauma stimulating a healing process
- Surgery; plantar fascia release at the calcaneus (performed endoscopically)
Remember, as nurses, we are lucky to work in a position that keeps us on our feet! From a health perspective, we do not face many of the health conditions related to prolonged sitting and sedentary desk jobs. There are industries dedicated to combat sedentary jobs by creating an “active office” – these interventions include standing desks, treadmill desks, and under-desk cycles, all focused on creating movement at work. This is already built into our jobs. I once spoke with a cardiologist about the importance of the standing desk option and she commented that “sitting is the new smoking,” stressing the importance of movement and avoidance of prolonged sitting due to adverse health consequences. As nurses, many of us have jobs with the built-in benefit of being on our feet. That said, we need to keep our feet healthy and feeling good for optimal job performance and comfort. The most effective way to prevent plantar fasciitis is to wear proper footwear at work, maintain a healthy weight, routinely stretch after a long shift, and if starting a new exercise or running program, build up to your goal rather than going all out on the first workout. Finally, pay attention to your feet, if you have pain, have it evaluated. In our busy work and home lives, let’s not forget to give our feet some attention.
