Detailed explanation-1: -A nerve conduction velocity (NCV) test measures how fast an electrical impulse moves through your nerve. NCV can identify nerve damage. This test is also called a nerve conduction study (NCS). During the test, your nerve is stimulated, often with electrode patches put on your skin.
Detailed explanation-2: -What is EMG/NCS? This is a specialized electrical test of your muscles and nerves. It consists of two parts. First NCV (Nerve Copnduction Study) is performed by a technologist using a small electrical impulse to stimulate the nerve and record the response from nerve/ muscle.
Detailed explanation-3: -NCV tests can measure the speed and strength of nerve signals. Nerve conduction velocity between 50 to 60 meters per second is considered normal. A damaged nerve may send a slower and weaker signal than a healthy one. It is possible to have normal results even if a person has nerve damage.
