RRA analisys in a lateral drop jump
I'm studying a drop jump and a lateral drop jump. RRA during a "simple" drop jump seems to give very "good" data. I'm also doing the RRA during the lateral drop jump but I can't improve the analysis. This is the results: ************************************************************ * Summary of Mass ...

Re: Lower limb model with knee abduction angle
Hi Josh. Thank you for your answer. I will check the paper you posted. I see the paper point to a knee model with ligaments and different DOF. I'm not a biomedical engineer and is not easy to work on it myself. I will check If I can extract some info and if is possible to perform CMC and/or FORWARD ...

Hi Josh, thank you for your reply.
Yes, I was thinking about the stability of the joint. How to insert ligament or contact point ?
There's any example somewhere ?
Thank you
Andrea

Re: Lower limb model with knee abduction angle
HI all. I did modify the ToyDropLanding model to add valgus/varus knee angle (tibia adduction/abduction) following the indication in the post and looking at the hip_adduction angle. Seems thug everything works fine. In this manner I added a DOF to the knee... but why to add an actuator ? There's no ...

I find a trick... after first scale if you close the scale panel and do another scaling from scratch on the model the error is not there...
