EMG is a recording of electrical activity from a small portion of a muscle supplied by a specific nerve, and is used to confirm a clinical diagnosis of a nerve or muscle disease or injury, and provides invaluable information helping to determine the severity, activity, location and type of problem you are having. A muscle is always studied both at rest, as well as during a light contraction. Click here for more information about normal & abnormal EMG findings. Our equipment is able to accurately measure the electrical activity, and with the doctors expertise, the patterns can be analyzed & interpreted. A never before or again used tiny sterilized pin electrode is utilized that is inserted into a few of your muscles. The wave patterns &sounds will be displayed on our equipment, and recorded if indicated. You will feel the prick as the pin electrode goes through the skin followed by a milder deeper aching sensation. It is important to relax your muscles during the test. With relaxation, the pin is frequently not felt after going through the skin. When the examination is over, very little discomfort remains for most. There is a possibility for bruising but only a very remote possibility for infection, among other rare complications. At times a quickly evaporating cold spray is used to provide slight topical numbing. After the study, you should be able to resume your daily routine.
NCS determines how well an electrical impulse travels through your nerves. We create a series of mild electrical shocks at different places along the course of a nerve while recording the responses. The shock is usually not painful and more of a surprise, although can cause the muscle being tested to twitch or contract. Click here for more information about normal & abnormal NCS findings.
The examinations are done while you are lying either on your back, side or abdomen. It takes about 30 – 60 minutes for a one to two extremity examination. Everything possible has been done with this test to keep any pain that you may experience to a minimum, but you have the right to stop the procedure at any time. In excess of 4500 of these examinations are done each year in our office, and all of our Electrodiagnostic physician specialists are highly trained with additional Board Certification held by the American Board of Neuromuscular and Electrodiagnostic Medicine/AANEM.
After the examination, the results are sent to your referring physician or health provider, and he/she considers the results to make the best decision about the next step in your treatment. Please let us know if you:
- Are on “blood thinners” such as Coumadin/Warfarin, or others.
- Have a bleeding disorder such as Hemophilia.
- Have a Pacemaker/Defibrillator unit (cardiac implant).
- Have a deep brain stimulator.
- Are allergic to Latex or any other topical product.
If you have special needs, please let us know . . . Thank you for your cooperation !
