Electromyography (EMG) is a diagnostic procedure that is used to assess the health of muscles and nerves. It is performed in an examination room with a machine designed to study nerves and muscles.  A combination of two studies is performed: a nerve conduction study which is used to study nerve function such as strength and speed using electrical current, and a needle electrode study which is used to assess the electrical activity of and nerve function to a particular muscle.

        The physician will use both of these studies to determine the health of various nerves and muscles to help accurately diagnose a patient’s condition.  EMG studies are commonly performed when a disorder of either a nerve or muscle is suspected, and each study usually requires 30-45 minutes.  A preliminary discussion of the findings will occur following the study, and a final report will be sent to the referring physician and whomever else the patient requests.

​

        It is common for a patient to be referred for an EMG study when the person is experiencing pain, tingling, burning, numbness, or weakness to a part of the body.  Since each person is unique, a discussion with the physician occurs prior to each procedure to help direct the study.  At that time a patient may ask questions regarding the procedure.  A preliminary explanation of the findings occurs following each study with time to ask the physician questions.
