ALTERATIONS IN LANDING MECHANICS DURING FORWARD JUMP IN INDIVIDUALS WITH CHRONIC ANKLE INSTABILITY
Keywords: ankle sprain, sport injury, single-leg landing, functional test
AbstractThe purpose of this study was to investigate the effects of different distance forward jump among the healthy control, coper, and CAI groups. Participants were asked to perform a single-leg forward hop and followed with a single-leg landing on the force plate. The forward jump distance was standardized to 50%, 100%, and 150% of leg length from the center of the force platform. Results from the current study indicated two major findings: the CAI group were use greater ankle external rotation to avoid the possibility of ankle sprains during single-leg landings. During descending phase of landing, the CAI group demonstrated a greater medio-lateral GRF compared to healthy group. Our findings indicated that different landing strategy of ankle joints exist among 3 groups.
