What to expect at your electromyography (EMG) and nerve conduction velocity (NCV) test

Your doctor has ordered electromyography (EMG) and nerve conduction velocity (NCV) testing to help evaluate and treat problems related to your nerves or muscles. The following information should answer most of your questions about the test. If you need more information, feel free to ask us anything before, during or after the test. Just relax, and you’ll do fine. What does EMG mean? EMG simply means measuring the electrical activity of the muscles. Normal muscles give off a certain size, shape and sound of electrical signal. Muscles that have a damaged nerve simply give off very different electrical signals. Therefore, analyzing the abnormal electrical signals in your muscles will help your doctor locate the specific site, nature and extent of nerve damage, if any. What problems are diagnosed by EMG? Essentially, EMG is used to diagnose any problem relating to nerves in the spine, arms or legs. These conditions usually cause pain, numbness, tingling or muscle weakness in part of the body. Examples of some of these conditions include: Pinched nerves in the neck or back, from disc problems or arthritis Compressed nerves in the wrist (carpal tunnel syndrome, at the elbow, knee or other areas) Neuropathies, such as the numbness in the hands and feet, due to diabetes How is an EMG done? While you are lying in a comfortable position on the table, a tiny needle is inserted into your affected muscle. Electrical signals are recorded at rest and as you slightly flex the the muscle. A series of different muscles will be tested. To learn more about ELECTRODIAGNOSTIC MEDICINE (EMG/NCV) Please visit Jewettortho.com
