The EMG/NCV Tests

The EMG/NCV test is usually prescribed when you feel weakness, numbness or soreness in the muscles. The test is conducted to identify whether the problem lies in the muscle or the nerve. You could be experiencing numbness, tingling, cramping, pain or weakness in your legs, back, wrist or any other part of your body.

The NCV and EMG tests can detect an injured nerve. Conditions that can be detected or ruled out are muscular dystrophy, carpal tunnel syndrome, herniated disk, Guillian-Barre syndrome, pinched nerves, and other conditions. If you are recovering from a nerve injury, NCV can analyze its progress.

“NCV” is the abbreviation of Nerve Conduction Velocity test. It is also called nerve conduction study (NCS) and is usually performed with the EMG or electromyography. While the EMG helps detect any disease affecting the nerves and muscles by recording electrical signals passing through the muscles, the NCV test assesses any nerve dysfunction or damage by measuring the speed at which electrical signals travel through the peripheral nerves.


The Procedures

The NCV test is done with the help of electrode patches that are attached to the patient’s skin on the region where the nerve runs beneath. One electrode transmits an electrical impulse mildly to the respective nerve. The response of the nerve is recorded by the other electrodes. The speed at which the signal travels indicates the health of the nerve.

The EMG test involves an electrode as well as a thin needle penetrating the skin right down to your muscle. You will be asked to contract the concerned muscle. The test ultimately identifies whether your muscles have responded to nerve signals well.
