EMG (Electromyography): What It Is, Purpose, Procedure & Results
Neurologists use electromyography (EMG) to help diagnose injuries and conditions that affect your muscles and the nerves that control them, such as carpal tunnel syndrome and muscular dystrophy. They often use this test alongside a nerve conduction study.
