P 054 –Evaluation of ground reaction forces by inverse dynamics analysis

The inverse dynamics simulation of the musculoskeletal system is a common method to analyse human motion. To obtain the ground reaction forces (GRF), measuring them experimentally provides accurate results. However, the number of steps is limited to the number of force platforms available in the lab. Several numerical methods have been proposed to compute the GRF using a model of the foot. Compliant models use simple equations, the local contact compliance can be hard to estimate. Rigid models usually require a priori information about the gait cycle.
