Just wanted to say that I've had now maybe 5 or 6 EMG/NCS (Nerve Conduction Study) and each has been quite different. The first one was so vigourous that the young neurologist literally dislocated my knee while attempting to induce a charlie-horse while the needle was several inches into my calf. (But he got some very good data.) The next one at the Mayo Clinic tried to induce a spasm with a computer controlled series of short bursts through the stun gun that I still remember 5 years on. But then I had one done last week by a relatively senior professor of medicine at UCLA and it was almost as gentle as a baby's breath. And he still got good data!

Moral of the story: I would error on the side of having it done - if it must be done - by someone whose been doing it for a very long time, recognizing that in many hospitals, it's an entry level job for staff neurologists.
