Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). Motor neurons transmit electrical signals that cause muscles to contract. An EMG translates these signals into graphs, sounds or numerical values that a specialist interprets.
Needle EMG refers to the recording and study of electrical activity of muscle using a needle electrode. EMG assesses the integrity of lower motor neurons, neuromuscular junction and the muscle itself.
