It should usually be done during the same visit as an NCV. This measures the electrical activity in your muscles. ![]() The speed is then calculated by measuring the distance between electrodes and the time it takes for electrical impulses to travel between electrodes.Ī related test that may be done is electromyography (EMG). This is repeated for each nerve being tested. The resulting electrical activity is recorded by another electrode. One electrode stimulates your nerve with a very mild electrical impulse. Two electrodes are placed on the skin over your nerve or over a muscle. This test is also called a nerve conduction study (NCS).ĭuring the test, your nerve is stimulated, often with electrode patches put on your skin. What is a nerve conduction velocity test?Ī nerve conduction velocity (NCV) test measures how fast an electrical impulse moves through your nerve.
