MODEL RELEASED. Electromyogram (EMG) test. Woman patient has the electrical activity of the muscles in her arm tested by electromyography. There are two radiologists in attendance. Electrodes have been attached to the patient's wrist & finger,and a sensor is being held at her neck. On the screen of the monitor (at lower left) are a series of electromyograms,a graphic record of muscle contraction as a result of electrical stimulation. An EMG can reveal the presence of muscle disorders such as muscular dystrophy,or disorders in which the nerve supply to muscle is impaired such as neuropathy or radiculopathy. A site of nerve damage may also be determined | |
