What are EMG (Electromyography) and NCS (Nerve Conduction Studies)?
Electromyography (EMG) is a test that is used to measure the electrical impulses in your muscles in order to learn more about the location and extent of diseases of muscle tissue and nerves. Nerve conduction studies (NCS), or electroneurography, are used to study how well a nerve can send an electrical signal from the spinal cord to the muscle. Both of these tests are commonly done together for patients who have weakness, decreased muscle strength, numbness, pain, or other problems in order to learn more about the injury or disease.
