Take Home Message: Ankle braces and balance training can reduce the risk of ankle sprains among competitive athletes.

Ankles sprains are common, lead to prolonged disability, and lead to a high risk of recurrence. Health care professionals are eager to implement prophylactic interventions; however, it is unclear how to select the most effective approach. Hence, the authors conducted a systematic review to compare the effect of an ankle brace or balance training on reducing the risk of ankle sprains among competitive athletes. The authors conducted a standardized literature search of four databases to find randomized clinical trials from 2005 to 2016 that reported the incidence of ankle sprains among competitive athletes who completed balance training, received a brace, or were assigned to a control group. They found 8 studies that included 7,195 (36% female) high school to professional athletes across multiple sports (basketball, football, volleyball, and soccer). Incidence of ankle sprains were not limited to lateral sprains, but also included medial, high, and syndesmotic sprains. Based on 3 studies, athletes wearing ankle braces had a 64% reduced risk of sustaining an ankle sprain compared to athletes receiving no-treatment. Similarly, athletes who completed balance training had a 46% reduction in risk of injury compared to controls. The authors were unable to control for history of ankle sprains subsequently limiting the conclusion of these methods at reducing the risk for a recurrent sprain or first-time occurrence.

This systematic review highlights the impact prophylactic approaches can have on reducing the risk of ankle sprains among competitive athletes. The balance training protocols included in this analysis were very different but used a similar progression of major components (double limb to single limb; eyes open to eyes closed; stable to unstable surface, and perturbations to upper extremity motion). While differences in protocols may have affected the overall relative risk assessment in this study, it is realistic. Clinicians often adopt different protocols depending on their athletes and setting/equipment. If a clinician feels their setting does not have enough time for a balance training program, then they may consider using ankle braces but this is a more costly approach. Unfortunately, the effectiveness of incorporating both balance training and ankle braces were not examined in this systematic review. Overall, clinicians should consider implementing a balance training program or requiring ankle braces for their athletes if they wish to see a reduction in ankle sprains.

Questions for Discussion: Do you require athletes to wear ankle braces or complete balance training, regardless of ankle sprain history? What is your preferred method for preventing ankle sprains among athletes?
