I am planing to apply EMS on upper extremity muscles and observe muscle using sEMG and MMG. I am wondering how to do the normalization in case of EMS? is it same as in the case of normal sEMG and MMG i.e. dividing the sub-maximal signals with the signals obtained during MVC?
Hi Jawad, I've always felt it was ideal to at least stick with the same analysis method for both the submaximal and maximal contractions. So if the submaximal stimulation is a series of spikes at a certain frequency, and peak-to-peak (P-P) is the most appropriate method to get the amplitude, then you'd want the same for the maximal signal. However, P-P does not work well with MVCs, so a maximal M-wave from electrical nerve stimulation would be optimal. If that is not an option, and normalization can only occur with an MVC, then I'd use RMS as your analysis method for both the muscle stimulation and MVC (and not P-P).
