What is an EMG or NCV?

• These are commonly preformed procedures that are a direct extension of the physical examination. They detect nerve and muscle disorders.

• An EMG specifically tests the electrical activity of the muscles. Disposable pin electrodes are inserted into the muscle to record their activity.

• A NCV specifically tests how well signals travel along a nerve and the time it takes muscle to respond to these signals. Stimulating and recording electrodes are used on the surface of the skin.

 Why should I have these procedures?

• To evaluate the causes of numbness, tingling, pain, weakness, fatigue, spasms, and paralysis.

• To diagnose carpal tunnel syndrome, muscular dystrophy, fatigue, myasthenia gravis, ALS (Lou Gehrig’s disease), and pinched nerves.

• To determine if the problem involves the muscles, nerves, spinal cord or brain.

 How do I prepare for these tests?

• Shower on the day of your test to remove body oils.

• Do not use any bath oils, lotions, or creams after you shower. Oils can interfere with the performance of you test.

• Eat your normal meals.

• Report all medication, especially blood thinners.

• Report if you have diabetes, hemophilia, pacemaker or a skin infection.

• RELAX. Tension and anxiety can interfere with your test.
