NCS is a noninvasive outpatient exam that measures how quickly nerves conduct electrical signals through the body. If nerve damage exists, NCS can help find its source.
Electrodes are placed on the surface of the skin at various locations. Mild electrical currents are sent into the body through stimulating electrodes. These signals travel through the target nerve and are detected by recording electrodes. This provides a precise measurement of the speed and strength of the nerve’s response to direct stimulation.
