Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

Ways You Can Help

Please bring with you a list of your current medications. This includes prescription medications, over-the-counter medications, vitamin or mineral supplements and herbal remedies.
Shower or bathe and DO NOT apply any lotions or creams to your skin.
You may eat a normal diet and take your medications as prescribed by your doctor EXCEPT if you have myasthenia gravis, do not take Mestinon before the test.
Wear comfortable clothing with a front button/zipper (NO pullovers).
When you arrive at the Neurophysiology Lab, check in at the reception desk. Please have the following ready:
Tell the doctor or technologist before the test if you are on blood thinners or have hemophilia.
Tell the doctor or technologist if you have a cardiac pacemaker or use a transcutaneous nerve stimulator.
To conduct an EMG procedure, the physician puts a fine needle into a muscle. You will be asked to make movements and the activity will be recorded.
To conduct the nerve conduction studies, we put strips at different places along the nerve and muscle and apply short pulses to elicit a nerve/muscle response. Some people find the test uncomfortable.
No specific care is required after the test. You may develop some mild bruising where the needle was inserted.
You will be seen by a technologist and a doctor during the test. It may take up to three hours depending on what is requested by the referring doctor.
