Thanks, Abby.

If you had EMGs as well as SEMGs, can you tell me the difference in the two? Meaning procedure. I've had 3 EMGs in which I got the needle and the zap. I would like to know what is different. I know the SEMG are going to target one nerve at a time, but are they longer? You mentioned you had to clench your muscle. I don't remember being asked to do that for the EMG. Is there anything else? Do they test the whole body or just the reported area of weakness?
