Tests and Procedures

Electromyography (EMG)

How you prepare

Food and medications

When you schedule your EMG, ask if you need to stop taking any prescription or over-the-counter medications before the exam. If you are taking a medication called Mestinon (pyridostigmine), you should specifically ask if this medication should be discontinued for the examination.

Bathing

Take a shower or bath shortly before your exam in order to remove oils from your skin. Don't apply lotions or creams before the exam.

Other precautions

The nervous system specialist (neurologist) conducting the EMG will need to know if you have certain medical conditions. Tell the neurologist and other EMG lab personnel if you:

  • Have a pacemaker or any other electrical medical device
  • Take blood-thinning medications
  • Have hemophilia, a blood-clotting disorder that causes prolonged bleeding
