Electrodiagnostic Testing (EMG)

Electrodiagnostic Testing (EMG)

Electrodiagnostic studies (sometimes called EMG for electromyography) are a commonly used technique to test the function of muscles and nerves.

The diagnosis and initial treatment of nerve problems, such as Carpal Tunnel Syndrome, are based upon taking a thorough history and the performance of a physical examination by your orthopedic doctor. 

An EMG is often requested to confirm the physician’s diagnosis, especially in cases where surgical treatment may be recommended.  Electrodiagnostic testing is also ordered when the cause of numbness and tingling or muscle weakness is unknown. 

The test consists of two parts and is performed in our physician’s office:

  1. Nerve Conduction Velocities (NCV): measures the speed at which electrical signals are transmitted down your nerve.
  2. Electromyelogram (EMG): measures the electrical activity of specific muscles in your upper extremity.

The results of the examination are recorded on a special computer screen to ensure accuracy and completeness of the information received. 

A nerve test typically requires 30-45 minutes to perform and you may experience minor aches during the test, but there are no activity restrictions once the examination is completed.

Test results will be discussed at your next clinic visit for further treatment recommendations.
