Ankle Sprains ImageThe reported recurrence rate for lateral ankle sprains (80%)  suggests that the healthcare community should continue to explore options that will protect our patients’ future health.1  Authors previously noted that immobilization of ankle sprains was a common treatment error.2  Early mobilization has proven more likely to prevent future ankle sprains.3,4  One good reason for early mobilization is that functional stress stimulates the incorporation of stronger replacement collagen.3  For grades I & II ankles sprains, Michael Wolfe, MD (Lewis Gale Clinic in Salem, VA) recommends that functional rehabilitation begin on the day of injury.2  More and more of the treatment protocol literature regarding acute ankle sprains now gives specific recommendations for functional stress, and it is likely that the healthcare community has improved its track record with this injury over the past decade.

 

Predictors for future ankle sprains include limited range of motion in the ankle (especially limited dorsiflexion),5 muscle weakness (especially peroneal),6-8 other mechanical instability, functional instability,9 and a history of ankle sprains.10  Functional instability refers to the sensation of an unstable joint due to neuromuscular deficits, as opposed to structural deficits such as lengthened ligaments.  For instance, Lofvenberg and colleagues found that patients with chronic ankle instability had 33% slower reaction times in the ipsilateral peroneus longus and tibialis anterior.11  Note that physical therapy can modify almost all of the predictors listed above.

 

Multiple studies now demonstrate physical therapy’s ability to speed recovery and prevent recurrent ankle sprains.2,3,6,12-18  A military series found that lack of specific rehabilitation for ankle sprains delayed return to full duty for several months.17  In a different study, Holme and colleagues compared patients receiving rehabilitation to patients receiving other usual care and found that the rehabilitation group had a 7% reinjury rate over one year vs. a 29% reinjury rate with the usual care group.14  Given the current drive to reduce overall healthcare costs, proactive measures to prevent recurrence of an injury with an 80% recurrence rate makes good sense.  At Balanced Physical Therapy, your patients can receive proactive therapy including pain relief and healing modalities, proprioceptive training, strengthening, prevention strategies including bracing, sports specific training, and a home exercise program.  Please refer all of your patients with ankle sprains to Balanced Physical Therapy.
