A member asked:

Thenar muscle smaller on dominant hand but completely clean emg and ncs. should i be concerned or can ths be a normal occurance?

A doctor has provided 1 answer

Normal variation: I seems that you have inquired about this with a physician, for you have had an evaluation, looking for a cause. The nerve conduction studies were normal, and if you are asymptomatic, no further evaluation is necessary.
