Predicting dynamic balance improvements following 4-weeks of balance training in chronic ankle instability patients

Balance training typically features as a central component of exercise-based rehabilitation programs for patients with lateral ankle sprain and chronic ankle instability (CAI). The purpose of this study was to conduct a responder/non-responder analysis using existing data to identify factors associa...

Description
Summary:Balance training typically features as a central component of exercise-based rehabilitation programs for patients with lateral ankle sprain and chronic ankle instability (CAI). The purpose of this study was to conduct a responder/non-responder analysis using existing data to identify factors associated with improvements in dynamic balance performance in CAI patients. Secondary data analysis. Data was used from 73 CAI patients who participated in 6 previous investigations that used the same balance training program. We defined treatment success as a patient exceeding the minimal detectable change score (8.15%) for the posteriomedial direction of the Star Excursion Balance Test (SEBT-PM). Baseline measures of participant and injury demographics, patient-reported function, and dynamic balance were entered into a step-wise logistic regression model to determine the best set of predictors of treatment success. Only 28 out of 73 patients (38.4%) demonstrated a successful improvement in SEBT-PM reach after balance training. Of the variables assessed, SEBT-PM reach distance ≤85.18% and self-reported function activities of daily living score ≤92.55% were significant predictors of treatment success (p
