How you prepare

By Mayo Clinic Staff

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

Questions to ask

When you schedule your EMG, you may want to ask the following questions:

  • What time do I need to arrive?
  • Where is the EMG lab, and what's the best way to find it in the hospital or clinic?
  • Do I need to stop taking any prescription or over-the-counter medications before the exam?
  • Can a friend or relative be with me during the exam?

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.
