Electromyography / Nerve Conduction (EMG/NCV)
EMG/NCV studies are conducted in two steps: first, the response of nerves to electrical stimulation is measured and, secondly, the function of muscles is tested through the insertion of tiny needles into various muscle groups.
- Physicians often request EMG/NCV tests to determine why you may be experiencing numbness, tingling, pain, weakness, spasms or muscle cramping.
- The NCV test requires using electricity first to stimulate nerves. Although this may be a little painful, most people do really well with this study.
- Bathe/shower on the morning of the exam. Scrub to remove any body oil. Do not use body lotion, oil or cream prior to the test.
- Take normal medications.
- Wear loose clothing. You may be asked to put on a gown.
- Avoid caffeine or tobacco a few hours before your test.
- Please inform the technologist and/or physician if you are fitted with a pacemaker.
- If you are on Coumadin or other blood thinners, please advise your doctor in advance.
- You should be able to return to your normal daily routine. If any discomfort or tenderness is felt, you may want to apply ice or a cold compress on the areas where the pin electrode was inserted.
