Electomyogram (EMG) / Nerve Conduction Study (NCV)
An electro diagnostic exam involves two parts – (1) nerve studies and (2) the needle exam. The nerves are then stimulated with a low level of electricity. This is often reported as feeling like small shocks similar to when one walks across a carpet with bare feet and touches something metal. The electrode picks up the electrical signals of the muscles. Small patches with “sticks” are placed on affected areas. The diameter of the needle electrode is much smaller than most needles used to draw blood and therefore usually causes only minimal discomfort. You can drive yourself to and from the test. It is recommended that you do not use moisturizing cream prior to the test. This test usually takes 45 to 60 minutes to complete.
