Detailed explanation-1: -A healthcare provider will attach a recording electrode to the skin over your nerve, using a special paste. He or she will then place a stimulating electrode away from the recording electrode, at a known distance. A mild and brief electrical shock, given through the stimulating electrode, will stimulate your nerve.
Detailed explanation-2: -Nerve conduction velocity (NCV) is a test to see how fast electrical signals move through a nerve. This test is done along with electromyography (EMG) to assess the muscles for abnormalities.
Detailed explanation-3: -The NCV test is usually done with surface patch electrodes similar to those used for an EKG (electrocardiogram). The patch electrodes are placed on the skin over the nerve at various locations. One electrode stimulates the nerve with a very mild electrical impulse.
Detailed explanation-4: -Electromyography (EMG) and nerve conduction studies are tests that measure the electrical activity of muscles and nerves.
