EMG Driven CMC

Post by Shivangi Giri » Thu Jul 30, 2020 12:00 am

Hi,
I would like suggestions on how I can use EMG activation values and implement them as muscle controls to conduct a CMC simulation. I tried using EMG values as control constraints in the CMC for one muscle but it does not seem to work. How can I verify that the implementation is happening correctly?
Please advise.

Regards,
Shivangi

See the CMC documentation about different settings files for more info on control constraints: https://simtk-confluence.stanford.edu/d ... raintsFile

Thanks Carmichael for your reply. I have already gone through this document. I want to set up muscle activations as x_nodes with values defined for each time frame. Here in the link, you have provided, the settings only talk about setting maximum and minimum values.
Can you please help in suggesting a way I can prescribe muscle activations in CMC that match the EMG?

Regards,
Shivangi

Perhaps set min = max value to the desired value?
