Abstract
The lower limb sidestepping kinematics of 20 elite female athletes were calculated using: 1) an established direct kinematic (DK) model (criterion) and, 2) two inverse kinematic (IK) models; one with and one without participant-specific joint co-ordinates
prescribed during model preparation. The aim of this research was to determine whether prescribing joint co-ordinates influences the accuracy of IK derived sidestepping
kinematics. Time-varying analysis (1D SPM) of IK derived hip, knee and ankle joint kinematics showed model’s prepared with participant-specific joint co-ordinates more closely matched that of the criterion measure. Prescribing participant-specific joint coordinates during model preparation improves the accuracy of IK derived sidestepping kinematics in OpenSim.
