Validation: do forces estimated from inverse dynamics reproduce the observed motion? 2. Understanding: how do muscle forces generate motion – what are the “cause and effect” relationships? 3. Prediction: “what if” a muscle or joint is altered, how will performance change? OpenSim Workshop NACOB 2008 Example of a Forward Dynamics Application Will knee flexion improve after muscle transfer surgery for a subject with stiff-knee gait?
