What is electromyography (EMG)?

An EMG is a procedure that The Rehab Doctors’ team uses to diagnose nerve and muscle problems. In this test, a state-of-the-art machine records your electrical muscle activity. 

Some of the many conditions that your doctor can potentially diagnose with an EMG include:

  • Peripheral neuropathy
  • Herniated disc
  • Muscle inflammation
  • Pinched nerves
  • Muscular dystrophy
  • Carpal tunnel syndrome
  • Ulnar neuropathy

The Rehab Doctors team may also use EMG to diagnose specific nerve issues before rhizotomy. 

When do I need an EMG?

If you're having muscle and/or nerve issues, such as tingling, numbness, muscle weakness, or muscle cramps, you may need an EMG for diagnostics. In addition to helping your doctor diagnose the root cause of your symptoms, an EMG can also identify the extent of the muscle or nerve damage.

How does an EMG work?

During a needle EMG, also called an intramuscular EMG, your doctor attaches a needle electrode with one or more very slim wires that go into your muscles. Your doctor asks you to relax and contract your affected muscle so they can monitor electrical activity at both times. 

During a needle EMG, your doctor may also perform a nerve conduction velocity test. During this test, they place additional electrodes (usually, surface electrodes) below the first. 

Your doctor stimulates your nerve using the needle electrode and then measures the response in the other electrodes. This test reveals how fast your nerve impulses travel and can help diagnose neuropathy and other kinds of nerve damage.

After your EMG, The Rehab Doctors’ team has valuable information they can use in your diagnosis and treatment planning. 

How do I prepare for an EMG?

The Rehab Doctors’ team gives you specific instructions ahead of your EMG. Usually, this includes avoiding lotion, oil, or cream on your skin and avoiding smoking for at least several hours before the procedure. Wear comfortable clothing in which it’s easy to expose the testing area and attach electrodes.
