Abstract

Inertial measurement units (IMUs) are commonly
used for measuring runners outside the lab, but current IMU-based motion capture solutions require a large number of sensors. Therefore, we propose an AI-driven inverse dynamics approach that requires three IMUs (placed on pelvis and lower legs) and pressure insoles to estimate lower-body kinematics and joint reaction moments during running. These joint reaction moments could give insight in the muscle contribution in joint loading, such as tibial bone loading. Results show good agreement with the reference for ankle reaction moments, while knee reaction moments have larger errors. The proposed method shows good potential, but better estimation of more proximal joint kinematics/kinetics is required in combination with measuring shear forces.
