EMG (Electromyography)
EMG (Electromyography)
EMG (Electromyography) is a specialized neurophysiological diagnostic test used to evaluate the electrical activity of muscles and the nerves controlling them. It helps diagnose neuromuscular disorders, nerve injuries, muscle diseases, and conditions affecting the peripheral nervous system. EMG is often performed along with Nerve Conduction Studies (NCS) for comprehensive assessment of nerve and muscle function.
