Hello,

Is there a way I can understand the similarity between EMG and muscle excitation?
Muscle excitations, as explained in OpenSim, is a combination of motor recruitment and firing frequency, and through EMG also, I think, we record almost the same thing.
So, can we assume both to be exactly same?

Regards,

There's a discussion of this in Hicks et al. "Is my model good enough? Best practices for verification and validation of musculoskeletal models and simulations of movement." ASME Journal of Biomechanical Engineering, 137(2):020905 (http://nmbl.stanford.edu/publications/pdf/Hicks2015.pdf, in the Case Study on page 17).

Thanks Thomas Uchida,

This paper is exactly what I wanted.
But it seems activations has to be taken, not excitation, along with the electromechanical delay, to compare with EMG data, as in paper. I'll go through it.
