Electromyography (EMG) - Nerve Test
Electromyography (EMG) is an electrodiagnostic test that measures the nerve impulses in muscles during contraction. Nerves throughout the body exchange information with the brain through nerve impulses. Healthy muscles need nerve input to perform movements. Doctors use EMG to identify muscle function as related to nerve input. EMGs help doctors diagnose neuromuscular disease, neurological disorders, muscle disease, and nerve abnormalities associated with pain or numbness.
