Hi, where would i find the source parameters for muscles by Millard, Thelen and Schutte?

Hi Darius,

Can you describe what you're looking for more specifically? Do you want a large set of muscle-specific parameters for maximum isometric force, optimal CC length, etc.? Are you using one of the public OpenSim models or your own custom model?

For modeling gait I find the paper associated with the Arnold 2010 model is a good starting point, it has all the major parameters for all the major lower limb muscles.

http://www.ncbi.nlm.nih.gov/pubmed/19957039

If I'm not using the Arnold musculoskeletal model itself, I'll then usually adjust the parameters so that my model's joint strength curves are similar to dynamometer data. Lots of ways of doing this, Hatze is the first reference I know of:

Good luck,
Ross
