NCV (Nerve Conduction Velocity Study)
NCV (Nerve Conduction Velocity Study)
NCV (Nerve Conduction Velocity Study) is a specialized neurophysiological diagnostic test used to measure the speed and strength of electrical signals traveling through peripheral nerves. It helps evaluate nerve function and diagnose nerve damage, neuropathies, nerve compression syndromes, and various neuromuscular disorders. NCV is commonly performed along with EMG (Electromyography) for a comprehensive assessment of the nervous system.
