Knowing the force profiles of individual muscles during various functional tasks may help to better identify various neuro-musculoskeletal impairments from functional movement analysis. Different simulation environments exist for this purpose. The aim of this study was to compare gait muscle force estimations (static optimisation) between the simulation environments AnyBody and OpenSim, using two similar musculoskeletal models. Results show mostly similar muscle forces, while some differences exist, resulting out of different anthropometrics and constraints of the generic models. The findings indicate the necessity to carefully analyse results when comparing muscle force estimations from different simulation environments. Future studies will develop a standardised protocol for such analyses.
