Abstract

Background: Ankle sprains are a common and potentially disabling injury. Successful prediction of susceptibility to ankle sprain injury with a simple test could allow ankle sprain prevention protocols to be initiated and help prevent disability in the athletic population. Objective: To investigate the ability of the single leg balance (SLB) test, carried out at preseason physical examination, to predict an ankle sprain during the autumn sports season. Design: Prospective cohort study Setting: High school varsity athletics and intercollegiate athletics. Main outcome measure: Ankle sprains in athletes with positive SLB tests. Results: The association between a positive SLB test and future ankle sprains was significant. Controlling for confounding variables, the relative risk for an ankle sprain with a positive SLB test was 2.54 (95% confidence interval, 1.02 to 6.03). Athletes with a positive SLB test who did not tape their ankles had an increased likelihood of developing ankle sprains. The relative risk for ankle sprain for a positive SLB test and negative taping was 8.82 (1.07 to 72.70). A history of previous ankle injury was not associated with future ankle sprains in this study. The κ value for interrater reliability for the SLB test was 0.898 (p<0.001). Conclusions: An association was demonstrated between a positive SLB test and ankle sprain. In athletes with a positive SLB test, not taping the ankle imposed an increased risk of sprain. The SLB test is a reliable and valid test for predicting ankle sprains.
