What is a Nerve conduction velocity test?
A nerve conduction velocity test (NCV) is a diagnostic procedure used to evaluate the function of the nerves and the myelin sheath that covers them. The test measures the speed at which electrical impulses travel through the nerves. Nerve conduction studies diagnose various nerve disorders, including carpal tunnel syndrome, Guillain-Barré syndrome, and diabetic neuropathy.
Overall, about 26 million Americans experience a nervous system disorder, according to the U.S. Centers for Disease Control and Prevention. About 4.8 million of these disorders fall into the category of epilepsy.
This test measures the speed and strength of signals passed through a nerve. This test can diagnose nervous system problems, such as carpal tunnel syndrome, peripheral neuropathy, and Guillain-Barré syndrome.
