EMG/NCV Q & A
What is an EMG/NCV?
EMG stands for electromyogram, and NCV stands for nerve conduction velocity. Both of these tests are used to assist in the diagnosis of neuromuscular diseases. While Dr. Cohen may be able to infer particular neuromuscular diseases based on your medical history, a physical exam, scans, and blood tests, EMG/NCV enables direct measurement of your nerve and muscle function.
Do I need to prepare for the EMG/NCV test?
No specific preparation is required and you may eat a regular meal beforehand. Be sure your physician or the technician performing the test knows if you’re on any medication, especially blood thinners like warfarin, have a pacemaker, or may be pregnant.
How does the EMG/NCV test work?
There are two stages to your EMG/NCV test. First, the staff at Chicago Neurological Services tests your nerves. Small electrodes are taped to your skin, and an electrical stimulus is triggered in one of your nerves, which causes a twitch in your arm or leg. Between two and six nerves are tested, with the entire diagnostic procedure usually lasting from 20-45 minutes.
In the second stage, your muscles are examined. Dr. Cohen or a technician inserts a fine-tipped needle into your muscle and asks you to contract and relax that muscle. This test measures muscle activity.
There may be some discomfort during the EMG/NCV tests, but it only lasts for a very short time. Afterward, you can resume normal activities. If discomfort persists, a warm compress and over-the-counter pain medication, like ibuprofen or acetaminophen, should relieve it.
What can the EMG/NCV test indicate?
Dr. Cohen interprets the results and incorporates them into the other information he has collected so far about your overall health and any symptoms you’re experiencing. He shares his diagnosis and makes sure you understand the implications. He may reach a conclusion, as conditions that are diagnosed with the aid of an EMG/NCV test can include:
- Neuropathy
- Muscle disorders
- Pinched nerves such as sciatica or cervical or lumbar radiculopathy
- Entrapped nerves such as carpal tunnel syndrome (CTS)
