EMG
Pronunciation: E-M-G
Also written as: EMG — Electromyography
Electromyography testing that measures electrical activity in muscles to diagnose neuromuscular conditions.
Full Definition
Electromyography (EMG) is a diagnostic procedure that evaluates the electrical activity produced by skeletal muscles at rest and during voluntary contraction. In rehabilitation medicine, EMG studies help differentiate between muscle and nerve pathology, guide treatment planning, and monitor recovery progress. The test involves insertion of needle electrodes into muscles or surface electrodes on the skin. EMG findings inform rehabilitation strategies, particularly for patients with peripheral neuropathies, radiculopathies, or myopathies requiring targeted therapeutic interventions.
