The Electromyography (EMG) is a diagnostic test used to evaluate the body’s nerve and muscle function and assesses a potential neurological disease. The test may be performed in combination with a Nerve Conduction Study (NCS) test, which together, help to detect the presence, location, and extent of diseases that damage the nerves and muscles.
