Nerve Conduction Velocity (NCV)

If you are experiencing numbness, tingling and/or burning sensations in your legs or arms, your physician may order a nerve conduction velocity test to determine if nerve damage has occurred. The acclaimed neurologists at Jefferson Hospital for Neuroscience perform this test to assist in accurately diagnosing your condition.

What Does a Nerve Conduction Velocity Test Involve?

During the test, the nerve is stimulated, usually with surface electrode patches attached to the skin. Two electrodes are placed on the skin over the nerve. One electrode stimulates the nerve with a very mild electrical impulse and the other electrode records it. The resulting electrical activity is recorded by another electrode. This is repeated for each nerve being tested.

Evaluating and diagnosing damage to the nervous system is complicated and complex. Many of the same symptoms occur in different combinations among the different disorders. To further complicate the diagnostic process, many disorders do not have definitive causes, markers or tests. Jefferson Hospital for Neuroscience is the only hospital dedicated to neuroscience in the region and is staffed by experts who are skilled in diagnosing and treating these complex conditions.
