Large and Increasing FY value in RRA
Posted: Wed Jul 12, 2017 6:56 am
I have written a script to run through an OpenSim pipeline for a number of subjects, with two sessions per subjects (8 weeks apart).
I am getting high FY values for RRA, but only in the second session for each subject. It seems really strange! I have compared the force plate forces across sessions, as well as IK and ID, an they seem to be the same across sessions, and the results only seem to differ when it gets to RRA, where suddenly FY is way out. All of the FY RRA values seem to end around 52.
The only thing I can see is that the subjects are the same weight across sessions (8 weeks apart). Can small changes in weight, gain or loss, account for such large RRA values?
Thank you for your help
Kind regards,
Julian
