    Abstract

    ABSTRACT: Study Design Controlled laboratory study. Objective To utilize kinematic and stabilometric measures to compare dynamic balance during performance of the Star Excursion Balance Test (SEBT) between persons 6-months post first-time lateral ankle sprain (LAS) and a non-injured control group. Background Biomechanical evaluation of dynamic balance in persons following first-time LAS during SEBT performance could provide insight into the mechanism(s) by which individuals proceed to recover fully, or develop chronic ankle instability. Methods Sagittal-plane kinematics of the lower extremity and the center of pressure (COP) path during the performance of the anterior (ANT), posterior-lateral (PL) and posterior-medial (PM) reach directions of the SEBT were obtained from 69 participants, 6 months following first-time acute LAS. Data also were obtained from 20 non-injured controls. Results The LAS group displayed lower normalized reach distances in all 3 reach directions compared to control participants on their injured and non-injured limbs with the largest observed effect size in the PL direction (p = 0.001, ηp(2) = 0.07). The performance impairment was associated with less hip and knee flexion and ankle dorsiflexion at the point of maximum reach (p
