What are EMG / NCS?
EMG, or electromyogram, is a diagnostic test performed by a physician to determine if the body has a nerve or muscle problem. It generally consists of two parts, nerve conduction studies (NCS) and EMG. The testing involves small shocks to stimulate the nerves, and the insertion of tiny needle electrodes through the skin into the muscles. The responses are recorded and analyzed. The results help locate which nerve root may be causing leg pain (sciatica).
