A nerve conduction velocity (NCV) test — also called a nerve conduction study (NCS) — measures how fast an electrical impulse moves through your nerve. NCV can identify nerve damage. During the test, your nerve is stimulated, usually with electrode patches attached to your skin.

What is nerve conduction velocity? Also called an electroneurography, EneG, or nerve conduction study, a nerve conduction velocity (NCV) test is a measurement of the speed of conduction of an electrical impulse through a nerve. NCV can determine nerve damage and destruction.

How does a doctor diagnose nerve damage?
CT or MRI scans can look for herniated disks, pinched (compressed) nerves, tumors or other abnormalities affecting the blood vessels and bones. Nerve function tests. Electromyography (EMG) records electrical activity in your muscles to detect nerve damage.What are the signs of nerve damage?

- Muscle weakness, especially in your arms or legs.
