Inverse dynamics - MTP, shoulder
Posted: Tue Sep 03, 2019 11:41 pm
Hi.
I have two questions about inverse dynamics.
First, I want to make sure if the moments are calculated sequentially from the MTP joint when GRFs are applied to the toes during inverse dynamics. When I compared the ankle moments with and without MTP joint locked, those were same. (I divided the GRFs and applied the force to the toes when simulating without MTP joint locked.)
Second, how can the inverse dynamics of a shoulder without GRF data be done?
I think those questions are basic, but I couldn't find the right answers. (I've searched it in the OpenSim Documentation but there's only a simple equation.)
It would be very appreciated and helped a lot if someone answers me.
Thanks.
