Electromyography (EMG) is a diagnostic procedure performed by physiatrists to evaluate the health of muscles and the nerves controlling them, known as motor neurons. This test helps pinpoint the cause of various neuromuscular disorders and guides treatment plans.
Key elements of EMG treatment:
During an EMG, a physiatrist inserts a thin needle electrode into the patient's muscle to record electrical activity. The electrode detects signals, which are then displayed on a computer screen or heard through a speaker. Patients may experience minimal discomfort during the procedure.
Surface EMG, a non-invasive alternative, uses electrodes placed on the skin instead of inserting needles. This method is less precise but still provides valuable information.
EMG results help physiatrists diagnose conditions such as:
