What is a Electromyography (EMG)

Symptoms of numbness, tingling, pain and discomfort can be alarming, especially when you don’t know what is causing the issue. An EMG, or Electromyogram, is a study conducted by a physician to find the cause of these sensations. An EMG test measures the electrical activity in muscles and nerves and determines where there may be a problem.

There are two components to an EMG test: the nerve conduction study and the needle EMG. Both can help determine whether there is a muscle problem or problems in the nerves that control the muscle. The first step is the nerve conduction study, which allows doctors to evaluate a muscle’s ability to respond to nerve stimulation. The second is the placement of one or more small needles, or electrodes, in the muscle, which determines if electrical signals are normal.


EMG testing is an essential diagnostic tool that gives insight to disease or injury. The test is conducted in an exam room and usually takes less than 45 minutes to perform. The results are charted by a graph and interpreted by your physician. It is a beneficial tool in determining a proper treatment plan for you going forward.

Some conditions that can be diagnosed with EMG testing are:

  1. Carpal Tunnel Syndrome
  2. Peripheral Neropathy
  3. Sciatica
  4. Herniated Disc
  5. Guillain- Barre Syndrome
  6. Ulnar (Funny Bone) Neuropathy
  7. Cervical or Lumbar Radiculopathy (Pinched Nerve in the Neck or Low Back)
  8. Other Peripheral Nerve Entrapments
