Modelling / Simulation
The purpose of this study was to compare the knee joint loads (forces and impulse), compare muscle contribution to knee joint loads, and examine associations between knee flexion angle and knee joint loads during a forward jump-landing task in people with chronic ankle instability (CAI). Eight people with CAI and eight healthy controls performed forward jump-landings. Kinetics and kinematics were calculated using musculoskeletal modelling. There was no significant difference in knee joint loads and muscle contributions between groups. However, there were significant associations between knee flexion angle and knee anteroposterior force and impulse for each group separately and all participants combined. Our results may indicate that while CAI does not affect the knee joint loads, greater knee flexion angles may increase knee loading.
