Procedure Description:
NERVE CONDUCTION STUDY

What To Expect:
Nerve conduction studies are usually done before an EMG. NCS testing may take from 15 minutes to hour or more, depending upon how many ares of the body are studied.

You will feel a brief, burning pain, a tingling sensation and a twitching of the muscle each time the electrical pulse is applied. It feels similar to the kind of tingling you feel when your rub your feet on the carpet and then touch a metal object.

Preprocedure:
Several flat metal disc electrodes are attached to your skin with tape. A shock emitting electrode is placed directly over the nerve to be studied and a recording electrode is placed over the muscles supplied by that nerve. Repeated, brief electrical pulses are administered to the nerve, and the time it takes for the muscle to contract in response to the electrical pulse is recorded.
