Model editing issue : muscle stiffness & external force

Hi, everyone. I'm trying to see change of hemiplegic gait with cable assistance. I'm using Moco to see the change of gait according to condition. However, I'm struggling to implement 3D hemiplegic gait. While editing model code to add patients characteristics, the change couldn't reflect the patient...

Re: How to predict hemiparetic gait

Hi Thank you for your advice. Following your advice, I tried to implement a hemiparetic gait. Because my goal is to see the change in hemiparetic gait according to cable assistance, I tried to observe the change in gait when various conditions are changed and it was based on Mocotrack example code. ...

Cannot open model after editing the file

Hi everyone. I tried to observe ankle angle with Opensim but there is no subtalar angle in coordinate windows. I checked the .osim file and the subtalar joint is constructed as WeldJoint. I guess they can't be shown in coordinates window because they are WeldJoint so I edited it as a CustomJoint. I ...

Re: How to predict hemiparetic gait

Hi I keep testing about asymmetric gait but I couldn't implement asymmetric gait which stroke patients really show. so, I have some guesses about the moco and i'll be really greatful if you give an opinons about these. First, even though I reduced muscle isometric force by 60%, speed of each leg whi...

Re: How to predict hemiparetic gait

I'm really thank you for your help. with the another code, i've simulated the asymmetric gait but the result is same as normal gait. I checked the model and the max isometric force and other kinematics features were modified for asymmetry. I thought if the model has no error then initial guess can b...

How to predict hemiparetic gait

Hi, Thanks to Moco team for supporting such an advanced tool. I have a question about assisting an hemiparetic gait. I want to make a hemiparetic gait but the motion deviation is very small. I read the paper about Mocotrack which simulate about the hip adduction/dorsiflexor weakness. as the paper sa...
