Generally, NCV is ordered to assess diseases of the peripheral nerves —those that connect from the muscles, organs, and skin to the spinal cord or brain. This test can be used to identify the type and location of nerve damage. Often, peripheral nerve conditions cause pain, sensory loss, tingling, or burning.
