1Purpose: The purpose of the present study was to evaluate lower limb kinematics and 2 muscular activities during walking, side-turning while walking, and side-cutting movement in 3 athletes with chronic ankle instability and compare the results to those of athletes without 4 chronic ankle instability. 5Methods: Lower limb kinematics and muscular activities were evaluated in 10 athletes with 6 chronic ankle instability and 10 healthy control athletes using a three-dimensional motion 7 analysis system and surface electromyography during the 200-ms pre-initial contact (IC) and 8 stance phases while walking, side-turning while walking, and side-cutting. Results: During walking or side-turning while walking, there were no significant differences 10 in kinematics or muscle activities between the subjects with and without chronic ankle

Abstract:4 Objective: To compare the kinematics of lower limb joints between individuals with 5 and without chronic ankle instability (CAI) during cross-turn and -cutting movements. Design: Cross-sectional study.
