Re: help with RRA

Hi Andrea, I had this problem with a model I am working on and found it was due to the application of the GRF data. I only have GRF's for a portion of the motion data (two force plates in the middle of the lab) so I run RRA for a time interval that I have the GRF's for. Specifically, I run RRA from ...

CMC ankle constraint

I am using the RunningSimulation model to develop a pipeline to study walking gait. I have run RRA with good average residuals for the timeframe when the right foot is in contact with the force plate in my grf data. When I run CMC for the same timeframe, the right ankle extends continuously througho...

Re: RRA with knee adduction

Hi Yusuke,

Thank you for the reply. I think I now have the problem sorted and it was due to a mistake by me in the actuator file that I had previously missed. I had added the actuators into the file but I had assigned them to the knee flex-ext angles rather than adduction.

Thanks again,
Peter

RRA with knee adduction

I have been using the running simulation model developed by Hamner, SR. to develop a pipeline for analyzing gait and have got RRA to run with good residuals (using the timeframe for when the right foot is in contact with the force plate in my grf data). I am interested in studying the knee adduction...
