Electromyography (EMG) is a diagnostic procedure that provides specific information about the extent and location of nerve and muscle injuries. If you are experiencing muscle spasms, weakness, or difficulty with certain routine tasks you may be a candidate for EMG. Typically there are two parts to an EMG test, a nerve conduction study, which measures the function of nerves, and a needle exam, which measures the electrical signals being given off by muscles. The results of these tests help pinpoint a proper diagnosis and help identify the specific treatment regimen that will work to alleviate the symptoms and resolve their underlying causes.
The entire EMG procedure takes 30 to 90 minutes. Some patients report minor discomfort, but most people tolerate the procedure extremely well. During the needle insertion you may experience small, sharp pricks and you may be able to feel the electrical impulses. Some people become anxious, but again, the procedure is not painful and is a very safe, effective and useful diagnostic tool.
You can return home and resume normal activities following the electromyography procedure. Some patients report mild soreness and tingling for up to 2 days, but the procedure is extremely well tolerated by most patients. There are very few risks associated with this test, but we will discuss them, along with any concerns you may have, prior to your appointment.
