I wonder if I can ask opinions on the optimal methods for determining the
onset of muscle contractions using sEMG. I have read various papers which
use a point at which the EMG amplitude increases by greater than 2 (or 3)
standard deivations, for a period of 25msec (or 50), from the baseline level
(taken 200msec prior to the commencement of the contraction).

Is this method in widespread use?
