An EMG is a diagnostic study of the nerve and muscles. This procedure assists in making a diagnosis to determine the cause of your symptoms. This test finds the real cause of your pain.
The EMG is actually two tests in one.
The first part is the Nerve Condition Velocity Test (NCV). The NCV tests the speed of the nerve impulse as it travels down the nerve. The NCV test evaluates the health of the nerve.
The information received identifies a problem area within the nerve and/or muscle. The NCV is the most helpful test for diagnosing Carpal Tunnel Syndrome and most other nerve related pain.
The second part of the test is the Electromyography (EMG). This test evaluates a specific muscle function. If there is nerve irritation, or a disorder that affects the muscle, this test will discover why you have pain.
Is there anything I need to do prior to the procedure?
Notify the physician prior to the procedure if you are taking any blood thinners or have any active infections.
