Abstract

To date, there is no comprehensive open-source tool to provide movement analysis of athletes using a running-specific prosthesis (RSP) with a below the knee amputation (BKA) to enable the calculation of corresponding inverse kinematics and dynamics. A combination of physical measurements, 2D imagery, 3D motion capture data and geometrical calculations were used to create a musculoskeletal full-body OpenSim model with subject-specific BKA structures. The model was able to reproduce athlete’s joint angles and joint moments of the lower extremities while allowing for movement comparison to non-amputee athletes. The model provides a motion analysis tool for athletes with a RSP in an open-source environment, providing qualitatively similar results to previous research, and lays the foundation for more insights into BKA athletes’ muscle activity and acting muscle forces.
