Nerve conduction study/electromyography is a two-part test completed by a trained professional. Your health care provider may recommend this procedure to further understand your neuropathy.
The nerve conduction study or NCS involves the nerves in your arms and legs. A tiny pulse of electricity is sent through your arm or leg and the nerve response is captured by a computer. This test allows the heath care provider to see how fast or slow your nerves react.
Electromyography or EMG gives important information about your muscles. During this test a very small needle is inserted into a specific muscle. You may be asked to relax or contract your muscles. During this test you may hear cracks, pops or static, which is your muscle working. The muscle activity is then captured by a computer. This test allows the health care provider to identify normal and abnormal muscle function.
