A procedure for testing and recording neuromuscular activity by electric stimulation of nerves.

Needle electrodes are inserted into any skeletal muscle being studied, electric current is applied to the electrodes, and neuromuscular functions are observed and recorded by means of instruments; such as, a cathode-ray oscilloscope and an appropriate recording device.

The procedure is helpful in the study of neuromuscular conduction, the extent of nerve lesions, and reflex responses.
