Re: Inverse Dynamics and Muscle Analysis Moment Differences

Yes, to compare the Muscle Analysis moment file and SO results I multiplied the forces found by SO with moment arms from the Muscle Analysis part of the Analyze tool. When I added all the individual moments and reserve torques (from the SO file), the solutions matched the ID net joint torque results...

Re: Inverse Dynamics and Muscle Analysis Moment Differences

Hi James, Thanks for posting that. I'm using Muscle Analysis from the Analyze tool instead of the Force Reporter, does that make a difference or should SO force results not be used as inputs for the Analyze tool at all? Also, if they shouldn't, what should be input instead? Thanks for your help! Cai...

Re: Inverse Dynamics and Muscle Analysis Moment Differences

Hi Colin,

Thanks for your answer. I'm using Static Optimization to calculate the muscle forces, and using the force outputs from SO as the forces file input for the analysis.

Inverse Dynamics and Muscle Analysis Moment Differences

Hello, We have been running analyses using exercise motion capture data. When trying to verify the results, we expected that the Inverse Dynamics net joint torques would match the sum of the individual muscle moments from the moment files created by the Muscle Analysis part of the Analyze tool for e...
