electromyographyProcess of graphically recording the electrical activity of muscle, which normally generates an electric current only when contracting or when its nerve is stimulated. Electrical impulses are shown as wavelike tracings on a cathode-ray oscilloscope and recorded as an electromyogram (EMG), usually along with audible signals. The EMG can show whether muscle weakness or wasting is due to nerve impairment (as in amyotrophic lateral sclerosis and poliomyelitis) or muscle impairment or disease (myopathy). |
