What to Expect During Your Test

Electrodiagnostic Medicine is the study of disorders of nerves and muscles.  Your doctor has trusted us to help determine why you have symptoms of numbness, tingling, pain, weakness, cramping, and/or abnormal movements.  After a focused history and physical examination, your electrodiagnostic physician will determine which tests to perform.  Common tests include nerve conduction studies (NCS) and electromyogram (EMG).

Nerve Conduction Studies (NCS) show how well the body’s electrical signals are traveling along a nerve.  This is accomplished by applying small electrical shocks to the skin over the nerve, and recording the nerve and/or muscle response.  The electrical stimulation may feel strange, but it is very safe and generally well-tolerated.

The Electromyogram (EMG) evaluates the electrical properties of the muscles, which are controlled by your nerves.  This involves placing a small, thin wire into selected muscles.  This may involve a small amount of pain, but it is safe, and tolerated by most patients.

Most patients inform us afterwards that the procedure really wasn’t as bad as they imagined!  For more detailed information, and to view a short video demonstrating the NCS and EMG tests, please click here.
