EMG-informed Computed Muscle Control

[Alex MacIntosh]

Hello,

I am trying to incorporate EMG into the CMC calculation. I have found the EMG-informed Computed Muscle Control project from: https://simtk.org/home/emg. When I looked in the source repository, I was unable to connect to the branch: Branches/JasonEmel485Project (as it is identified in the tutorial). I am not sure if it does not exist, has been moved, or if I am not using tortoiseSVN correctly.

Any comments or suggestions about how to incorporate EMG in the CMC algorithm would be a huge help.

Thanks so much,

Alex

Hi Alex,

I had difficulty as well. This looks like an old project, last updated in 2010. Perhaps email Emel directly.

Thanks James for your reply,

I have sent an e-mail and am just waiting a reply.

I am curious, did you find an alternative to incorporate EMG for your work?

Any ideas that you have would be a great help.

Thanks

Acouple of years ago I messed around with MuscleStateTrackingTask (doxygen: https://simtk.org/api_docs/opensim/api_ ... f221d7c7d7)

I was testing it out using the arm26 model and used a .sto files with the muscle controls to track. This was an attempt by the development team to have the EMG-assited cmc implemented in opensim. At the time (2010 Opensim ~2.1) it didnt work very well because somewhere in the CMC code it was switching labels (controls for biceps would be applied to triceps). I have not used it since then and am not aware of anyone that is currently. Im not even sure how (or even if) it is implemented in current versions. But it may be a possible avenue to test.

I may also give it a go to see if the issues have been fixed. If you do attempt it, get back to us with your progress

Thanks,

I will definitely let you know if I find anything.

Hi Alex,

Did you find JasonEmel485Project? Where can I download it?
Thank you!

Did anyone succeed in finding the EMG code?

I have data collected from sleep capture of EMG data during REM periods (U. of Texas).

I am new to OpenSim software but am interested in creating a simulation of motor behavior (including speech-related

behavior) in dreams (during REM, EMG signals are measurable, though diminutive due to sleep paralysis).

Any help will be appreciated.

This project may be of use

Thanks, James.
