Prepare for Your
EMG and Nerve Conduction Studies

These studies measure and record activity from the muscles and nerves. Your provider may order this test to assess symptoms of pain, numbness, tingling, or weakness.

Part of the study involves a small needle that is inserted into the muscle to record muscle activity. A mild electrical stimulus is given to stimulate the nerve and allow for recording of nerve function. You may experience some discomfort during the testing. Testing generally takes less than one hour.

To prepare for an EMG/NCS, please do the following:

• Bathe or shower on the day of the test; wash arms and legs well to remove body oils
• Don't use lotion, bath oils or creams
• Wear comfortable, loose-fitting clothes, and remember to bring shorts and a short-sleeved or sleeveless shirt
• Eat your normal meals (but you may wish to avoid tobacco or caffeine for a few hours prior to your test)
• Bring a list of medications you are taking
• If you are taking blood-thinning medications or pyridostigmine (Mestinon), please contact our office prior to your exam
• Tell the health care provider if you:
  • bruise easily
  • have hemophilia
  • have a pacemaker
  • have a skin infection

You may take over-the-counter pain medication if you wish, as they do not affect test results.
