Electromyography/Nerve Conduction Study (EMG/NCV)

The EMG/NCV is a testing modality that has been in clinical use for more than 50 years and continues to be a valuable diagnostic tool. It is important for detecting disorders of the nerves and muscles and diagnosing many conditions such as neuropathy, carpal tunnel syndrome, radiculopathy, and myopathy to name a few.

The test consists of two parts.  In the first part, the nerves are electrically stimulated and their responses are measured. The test is geared specifically towards each patient’s complaint and the physician’s findings during the test.
In the second part a tiny needle is placed into different muscle groups.  The needle picks up electrical signals from these muscles.

The test takes between 30 and 60 minutes, and although mildly uncomfortable, it should not be painful. Dr. Lehmann or Dr. Vennix place high priority on your comfort.

You can help ensure the best results if you relax. Make sure that you ask any questions that you have about the test before it is performed. Dr. Lehmann or Dr. Vennix will discuss the results with you.

On the day of the test:

  • Wear comfortable shorts (if testing a leg) or loose, short sleeve shirt (if testing an arm)
  • Eat normally and take medication as you usually would (advise staff if you are taking blood thinners)
  • Avoid bath oils or any skin lotions or emollients the day of the examination
