What To Expect: These tests help to evaluate and treat problems related to nerves or muscles.
NCV testing measures how fast an electrical impulse travels through nerves. While resting comfortably on a table, several small electrodes will be taped to your hand and foot. A small electrical stimulator will be placed on the skin and an electrical impulse will be given. The small shock may tingle or make your muscles twitch momentarily, but this is not harmful.
An EMG is performed by inserting a tiny needle into affected muscles. Electrical signals are recorded at rest and as you slightly flex the muscle. There is some discomfort when the needle is inserted but not so much that sedatives or anesthesia is required.
Preprocedure: You may eat regularly and take all the normal medications prior to the test. Do not apply any lotions, creams or oils that morning.
Postprocedure: You may experience some small areas of muscle soreness, but most people have no difficulty returning to their regular daily activities. Test results will be made available to you and your referring physician on the same day.
