![]() ![]() In an abnormal EMG result, strange patterns and wave shapes occur and there is electrical activity even at rest. During stimulation, muscles react in a smooth pattern. In normal EMG and NCS tests, no electrical activity occurs at rest. An EMG can be done by either inserting tiny electrodes through your skin into muscle or by using electrode stickers, which are placed on the surface of the skin. While the test is in progress, you will be asked to use certain movements which contract your muscles. This is a test that detects your body’s neuromuscular response to stimulation. A mild electrical impulse is administered to the skin right over the nerve to see how you react. NCS tests determine the health of your nerves. ![]() Nerve Conduction Studies (NCS) and Electromyography (EMG) are two parts of a test that are usually used together. An EMG test can be done alone, but generally is performed with NCS. If you suffer from sciatica, EMG and NCS tests can be a helpful tools in diagnosing and treating the pain. ![]()
