Neurodiagnostics

EMG and nerve conduction studies are two tests often done together to help give us the complete picture about what might be happening with muscle control and impulse traveling through the muscles. An EMG test looks at the electrical signals your muscles make when they are at rest and when they are being used. The doctor analyzes the electrical impulse traveling through the muscles. A Nerve Conduction Study (NCS) - a test that helps us learn how fast and how well the nerve signals travel. The health of nerves is measured to determine how these nerves are behaving or if there is a nerve disease. The test typically takes between 30-60 minutes. Occasionally, the test can last more than 1 hour.

Your provider has ordered this test to help determine the cause of your symptoms. This test is extremely important in making a diagnosis and directing your treatment.

Please tell the physician if you are:

• On any type of blood thinner such as; Coumadin, Xarelto, Eliquis, etc.
• Have any disorders that make you more likely to bleed, such as Hemophilia.
• Have a pacemaker or defibrillator.
• Deep Brain Stimulators.
• Cochlear Implants.

On the day of the test:

• Take a shower/bath to remove the natural oils from your skin.
• Do not use any lotions, powders, or gels.
• Wear loose-fitting pants such as sweatpants or a pair of shorts. Alternatively, a disposable pair of shorts will be available.
• Please wear underwear (and bras for women) on the day of exam. You will be changing into a gown.
• You may be asked to remove your shoes and socks.
• If you wear jewelry on your arms, legs, neck, please do not wear any jewelry other than your wedding/engagement ring.

During the test:

• You can watch this video to learn more about what to expect during the test.

You may return to your normal activities after the test is performed, unless told otherwise by the physician who will perform the test.

This is the most common question. The nerve conduction study may feel like having a tapping sensation on your nerves. The needle EMG feels like a sharp poke, sometimes followed by a muscle ache.

The test can be uncomfortable at times, but almost everyone can finish the test. Some people may have muscle soreness lasting up to a few days.

If you are afraid of needles, please have your referring provider prescribe you a medication to take 1 hour before the test so you are not as anxious.

If you are already in pain, please have your referring provider prescribe you a medication to take 1 hour before the test so you are more comfortable. If you already have a medication you take for pain, you can take that medication 1 hour before the tests.

As with all procedures, some risks are involved. Anytime the skin is broken by a needle, there is a risk of infection, pain at the site, swelling, bruising, or bleeding.

There are no lasting side effects although some may experience muscle soreness up to a few days.

There is no pre-certification required by our office. Depending on your insurance plan you may be responsible for a portion of your bill. We encourage you to call your insurance company prior to your testing appointment to see what you may be responsible for.
