Nerve Conduction Velocity (NCV) (Neurology)
Body Area: Back / Spine
Body Parts: Back
Symptoms: Numbness or Tingling
Nerve conduction velocity, or NCV is a test administered to record the speed of electrical signals through the nerve. In a NCV test, electrodes are attached onto a patient's skin at nerve sites that are stimulated by electrical impulses emitted from the electrodes. NCV results are related to the diameter of the nerve and the degree of myelination of the nerve. Abnormal results indicate nerve damage or destruction including, axonopathy, conduction block, and demyelination.
