Mrs. Manuela Bulhoes, registered medical electrophysiology technician, in the EMG laboratory.
What Is an EMG?
Electromyography (EMG) is used to study nerve and muscle function while radiology looks at structure and anatomy, therefore they are different and complementary techniques.
How to Get Ready for your EMG Test
No preparation is needed for the test, but please let us know if you are using anticoagulants (blood thinners). A relaxed state is most important during the exam as it leads to impeccable results.
The Examination Process
The examination lasts approximately 30 minutes and is performed by the neurologist. It is conducted in two parts: the first is to record the responses of nerves to low intensity electrical stimulation and the second is to determine the electrical activity of the muscles, which is done through inserting a small needle electrode into the muscle. We will do everything we can to minimize the mild discomfort caused by this examination.
Note that there is no injection for this examination.
Note that the results are not modified by the presence or absence of symptoms on the day of the test.
The results will be reported to the referring physician within two weeks and a follow-up visit to that physician is best scheduled at that time.
