Abstract

Biomechanical models allow for a comprehensive understanding of dynamic movements that could be used to assess athletic performance or identify injury risk and return to play status. In order to make clinical recommendations based on these model outputs, discrepancies between modelling approaches need to be identified. The purpose of this study was to compare the knee kinematics between the commonly used Plug-in Gait model and a six degrees of freedom model during the first landing a double leg drop jump (DLDJ). This study identified differences in the model outputs for knee kinematics, most prominently in the frontal and transverse planes. Further investigation is required to determine the reliability and sensitivity of these model outputs.
