Many of these individuals will incur repetitive episodes of lateral ankle sprain, resulting in chronic ankle instability (CAI). CAI has been heavily researched, but few conclusions have been drawn. Much of this research has focused on sagittal plane kinematics and kinetics. Therefore, the purpose of this study was to compare three-dimensional ankle joint kinetics during functional landing tasks in participants with CAI and uninjured controls. Participants performed single-leg vertical drop landings and single-leg cross-over landings. There were no significant differences between the two groups for ankle net joint moments (plantarflexion/dorsiflexion, inversion/eversion, internal/external rotation) and ankle net joint forces (axial, anterior/posterior, medial/lateral) at any time point from ground contact to 150 ms after. We conclude that those with CAI do not suffer from an alteration in motor programming, and are able to absorb forces upon landing similar to uninjured individuals.","abstract_html":"Lateral ankle sprains are a common injury sustained by physically active individuals.
