Author's abstract: This study was conducted to evaluate the coordination pattern stability of the lower extremity during a single-leg hop for distance, a commonly used tool in athletic rehabilitation programs and return-to-activity decisions. A dynamical systems analysis was utilized to examine single-leg hop performance of bilaterally healthy individuals and participants with unilateral chronic ankle instability (CAI). Each participant performed ten single-leg hops for distance on each leg while kinematic data were collected during takeoff and landing. Statistical comparisons of coordination pattern stability, using a deviation phase (DP) measurement, were made between groups (healthy vs. chronic ankle instability) and between leg segment couples (foot-shank, shank-thigh and thighpelvis ). There were no statistical differences between the dominant and nondominant legs of the healthy participants. Comparison of the CAI and healthy participants revealed a statistical trend towards increased DP values in the CAI involved foot-shank couple when compared to the healthy foot-shank.
