![]() The speed of the response is called the conduction velocity. The time it takes for the muscle to contract in response to the electrical pulse is recorded. Many people find this unpleasant but fortunately it does not last very long. The electrical pulses are very brief and feel like a sharp tapping sensation on the skin. Several quick electrical pulses are given to the nerve. If the nerve controls a muscle, a recording electrode is placed over the muscles under control of that nerve. Felt electrodes are usually mounted in a plastic holder and kept in place with a strip of Velcro®.Ī pulse-emitting electrode is placed directly over the nerve to be tested. The electrodes can be stick-on or made of small felt pads soaked in salt water solution. In this test, several electrodes are attached to your skin with tape or a special paste. What happens during nerve conduction studies?
