This webcast describes a study in which the validity of two gait models created in the musculoskeletal modelling programme AnyBody was investigated. The models used recorded force plate data and were driven kinematically with motion capture data. The contact force at the hip was calculated and compared to experimental data from instrumented hip prostheses available in the literature. Although there were some discrepancies between the model results and the literature data, the model results fell within the limits of patient to patient variation. To investigate the variation further, the torque at the hip, which is calculated directly from the force plate and kinematics data and is independent of the muscle recruitment model, was determined from the model and compared to the torque calculated for the literature subjects.
