About our Lab
The Dean Medical Group Electroneurodiagnostics Lab is a state-of-the-art diagnostic testing facility of electromyography (EMG) and nerve conduction studies (NCS). It is our mission to provide advanced, highest quality procedures in a professional and comfortable environment.
What is EMG/NCS?
The electro-neurodiagnostic studies are tests that tell your physician whether your nerves are functioning properly or if any muscles have been damaged. Your physician may suggest that you have an electromyogram (EMG) and nerve conduction study (NCS) to evaluate muscle weakness, numbness, tingling and pain.
Preparing for the Test
On the day of the procedure, please do not use hand or body lotion on the extremities that will be tested. You are able to take any prescribed medications. If the affected arm or leg is too cold, it may alter the results of this test. In winter, please try to arrive a few minutes early so that your arms or legs will have a chance to warm up. We may have to warm your limb with a moist heat pack.
Other types of EMG/NCS testing may be done and may require additional preparation instructions.
The testing takes approximately 30 - 60 minutes. You may be asked to change into a gown or shorts to expose the area where the test will be done. If you are having low back pain, the test will be done on your legs and back. For neck pain, it will be done on your arms and neck. Your nerves originate in your spine, but continue throughout the rest of your body.
The test will be performed by a board-certified neurologist with special training in electro-neurodiagnostic studies and/or the nerve conduction technologist. There are two parts to this procedure. The first is the nerve conduction study (NCS). The physician or technologist will attach wires to an electronic machine. This machine has a scope and gives a reading as he/she is doing the test. By giving a small electrical impulse, like a static charge, to different sections of the nerve, they can determine if the nerve is sending its message to the muscles with proper speed. Your arm or leg may jerk or jump, but the shock is not harmful.
The second part of the test, the electromyogram (EMG), is done by the physician inserting a very thin disposable needle electrode into several muscles. The number of muscles tested depends on what type of symptoms you are experiencing and is tailored at the time of the testing.
The test involves variable levels of discomfort, but is tolerated by most patients. The doctors and technologists doing the procedure have all experienced this test.
The EMG/NCS is a diagnostic test; it is not a treatment. It is not a form of acupuncture or therapy. There are no after-effects from the test and it will not interfere with driving. You may experience a temporary bruise from the needle testing in which an ice pack can be applied for 10 minutes at a time, if it is bothersome. If bruising persists, you should contact your primary doctor. After the test, a formal interpretation of the findings will be made and sent to your referring physician, for further care.
