Thank you for your reply! - The spikes do seem to be situated around the heel-strike and toe-off regions, although I didn't find any drastic force changes at the exact timepoints in the ground reaction forces. - I filtered both the raw marker data and ground reaction forces using a 4th order butterw...

Hello forum! I have some questions regarding residual forces encountered in static optimization. Context I am trying to use OpenSim to predict the knee joint contact forces during walking. For this, I am using the CAMs Knee dataset , which includes kinematic data (optical motion markers) and ground ...
