What is NCV (Nerve Conduction Velocity)?
Nerve Conduction Velocity (NCV) is a test of the speed of electrical signals through a nerve. Patches called electrodes are placed on the skin over the nerves at various points. This generates a mild electrical impulse to stimulate the nerve. The distance between electrodes and the time it takes for electrical impulses to travel between electrodes are used to determine the speed of the nerve signals.
