Simultaneous prediction of musculo-tendon, joint contact, ligament, and bone forces in the lower limb during gait

Abstract

Musculo-tendon forces and joint reaction forces are typically predicted by computing first the musculo-tendon forces by a static optimisation procedure and by then deducing the joint reaction forces from the force equilibrium. Moreover, the joint contact and ligament forces as well as the bone forces are rarely studied, because it requires complex models and multiscale simulations. This study presents a rigid multi-body musculo-skeletal model allowing to compute the musculo-tendon, joint contact, ligament and bone forces all together by static optimisation, using a weighted criterion. The predicted forces are compared to the subject's measurements (EMG, knee prothesis contact forces) and literature data.
