What to do before your test
Do not apply lotion, oil, or cream to your arms or legs on the day of the test. This is the most important preparation step. These products reduce electrical contact with the skin and can affect the accuracy of the study.
Take your medications as usual. No changes needed unless specifically instructed by our office.
Eat normally. No fasting required. Having a normal meal before the test is fine.
Wear loose, comfortable clothing. Shorts and a short-sleeve shirt or athletic wear. I'll need access to your arms and/or legs depending on what we're testing.
Inform us ahead of time if you: have a pacemaker or implanted defibrillator, take blood thinners, have a bleeding disorder, or are pregnant. These do not prevent the test from being done, but I may make minor modifications.
What to expect during the test
The test has two parts and typically takes 30 to 60 minutes.
Nerve conduction studies (NCS): Small electrode stickers are placed on your skin over specific nerves and muscles. Brief electrical impulses are delivered through the electrodes. You'll feel a quick snapping or buzzing sensation with each pulse. It's uncomfortable but very brief. Multiple nerves will be tested.
Needle EMG: A very thin needle electrode (similar to an acupuncture needle) is inserted into specific muscles. I'll ask you to relax, then gently contract the muscle. I listen to and record the electrical activity. The needle is moved to several muscles. You'll feel a brief pinch each time the needle is inserted. Mild aching during the test is normal.
After the test
You can drive, work, and resume all normal activities immediately.
You may have mild soreness or small bruises at the needle insertion sites. This resolves within a day or two.
No activity restrictions.
Getting your results
I perform and interpret the study myself, so I'll discuss the findings with you immediately after the test. You'll know what we found and what it means for your care before you leave. A formal written report will be sent to your referring provider.
Cancellation
If you need to reschedule, please give us at least 24 hours notice. EMG appointments are longer than standard visits and we hold dedicated time for them.
