MODEL RELEASED. Electromyography. Man undergoing an electromyography (EMG) test to examine the contraction of his arm muscle in response to electrical stimulation. The patient has a needle electrode placed in his arm. The screen (at right) shows the results of the test,which in this case is monitoring a biceps muscle. An EMG can reveal the presence of muscle disorders such as muscular dystrophy. It can also diagnose disorders in which the nerve supply to the muscle is impaired,such as neuropathy or radiculopathy. The test takes 30- 60 minutes and causes no side-effects. Photograph of a Medelec Sapphire Premier EMG system | |
