EMG (electromyography) and NCS (nerve conduction studies) test the electrical activity of your muscles and nerves. This allows the physicians to determine exactly where your injury is located. The tests may be done separately or together depending on your symptoms.
Nerve Conduction Study (NCV) – Nerve Conduction studies test the flow of electrical currents across your nerves. This test will help your physician detect if there is an abnormal nerve condition. NCV is usually ordered in patients who are experiencing weakness or numbness in the arms or legs and can help determine the severity of a nerve injury.
