 [e-lek″tro-mi´o-gram]
the record obtained by electromyography.

e·lec·tro·my·o·gram (EMG),

(ē-lek'trō-mī'ō-gram),
A graphic representation of the electric currents associated with muscular action.

electromyogram

(ĭ-lĕk′trō-mī′ə-grăm′)
n.
A graphic record of the electrical activity of a muscle as recorded by an electromyograph.

e·lec·tro·my·o·gram

(EMG) (ĕ-lek'trō-mī'ō-gram)
A graphic representation of the electric currents associated with muscular action.

Electromyogram (EMG)

A diagnostic test that records the electrical activity of muscles. In the test, small electrodes are placed on or in the skin; the patterns of electrical activity are projected on a screen or over a loudspeaker. This procedure is used to test for muscle disorders, including muscular dystrophy.

electromyogram (EMG)

Recording of electrical activity of a muscle associated with contraction and relaxation. This is obtained by placing a microelectrode within a muscle. The recording process is called electro-myography. See Sherrington's law of reciprocal innervation.

e·lec·tro·my·o·gram

(EMG) (ĕ-lek'trō-mī'ō-gram)
A graphic representation of the electric currents associated with muscular action.
