Electromyography (EMG). Electromyography (EMG) measures muscle response or electrical activity in response to a nerveâs stimulation of the muscle. The test is used to help detect neuromuscular abnormalities. During the test, one or more small needles (also called electrodes) are inserted through the skin into the muscle.
EMG is performed using a machine called the electromyograph, to produce a record called an electromyogram. An electromyogram detects the tiny amount of electricity generated by muscle cells when they are activated by the nerves connected to them.
