Experimental data and simulation results from ten healthy individuals walking on an instrumented treadmill. Participants were provided with real-time biofeedback instructing them to walk with greater soleus muscle activation and less gastrocnemius activation, with the goal of reducing knee contact force. A custom static optimization code that incorporated EMG into the muscle redundancy solution was used to estimate the effect of the altered coordination pattern on knee contact force.
