We have updated our Birchmount Hospital phone lines. When you call through the main line (416-495-2400), you will need to add “7” when dialing an extension.

Neurophysiology Testing

Electromyography (EMG)

Nerve conduction tests and electromyography (EMG) studies are performed to assess the heath of nerves and muscles. These tests can help with the diagnosis of nerve and muscle diseases such as neuropathy, ALS, muscular dystrophy and myasthenia gravis, among others.

Doctors often conduct EMG tests in conjunction with a nerve conductive study (NCS). An NCS test is another type of electro diagnostic test that doctors can use to identify damaged or impaired nerves.

We offer comprehensive, timely, outpatient consultation and follow-up for a wide range of conditions, from common disorders such as carpal tunnel syndrome, peripheral neuropathy, and radiculopathies, to complex neuromuscular disorders such as myasthenia gravis, inflammatory neuropathy (CIDP/GBS), ALS, and muscle disease.

Our clinic offers:

  • Nerve conduction testing and electromyography (EMG)
  • Repetitive nerve stimulation
  • Single fibre EMG

What should I do to prepare for the test?

  • Bathe or shower on the day or your test; wash arms and legs well to remove body oils. Do not use lotions, bath oils or creams on the skin.
  • Wear comfortable, loose-fitting clothes, and remember to bring shorts and a short-sleeved shirt.

How long is this test?
The test takes approximately 15 minutes to 1 hour from start to finish. A specially trained Physician and Technician will perform the test, keeping your comfort and safety in mind.

Does it hurt?
EMG testing may result in some discomfort, but it is usually well tolerated without and need for pain medication.

What will happen during the test?

  • You will be given an explanation before the test starts and have time to ask questions.
  • During the NCS you will be asked to sit or lie down. Electrode stickers are applied to the skin to measure the speed and strength of signals passing between two points.
  • During the EMG needle electrodes will be inserted directly into a muscle to record the activity in that muscle.
  • Once the recording begins, you will need to remain still throughout the test.

Although the technician performing the test can see what is occurring with your nerves and muscles, he/she cannot provide any information. The test must be read and interpreted by the Neurologist who will then send a report to the physician who requested the test and that physician will release the results of your test.

Electroencephalography (EEG)

An electroencephalogram procedure is used to detect abnormalities in your brain waves, or the in the electrical activity of your brain. This test is performed to diagnose seizures, as well as infection, stroke, tumours, metabolism disorders, head injuries etc. We offer both routine and sleep-deprived EEGs.

During the procedure, electrodes consisting of small non-invasive metal discs with thin wires are pasted to your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.

What should I do to prepare for the test?
Wash your hair the night before or the day or your test, but avoid conditioners, hair creams, sprays or styling gels. If you’re supposed to sleep during your EEG test, your doctor might ask you to sleep less or avoid sleep the night before your test.

How long is this test?
The test takes approximately 45 – 90 minutes from start to finish. A specially trained technician will perform the test, keeping your comfort and safety in mind.

Does it hurt?
EEG has been used for many years and is considered a safe procedure. The test causes no discomfort. The electrodes record activity. They do not produce any sensation.

What will happen during the test?

  • You will be given an explanation before the test starts and have time to ask questions
  • Between 16 and 25 electrodes will be attached to your scalp using a thick paste
  • You will be asked to close your eyes, relax and be still
  • Once the recording begins, you will need to remain still throughout the test
  • If you are being evaluated for a sleep disorder, the EEG may be done while you are asleep

Although the technician performing the test can see what is occurring with your brain, he/she cannot provide any information. The test must be read and interpreted by the Neurologist who will then send a report to the physician who requested the test and that physician will release the results of your test.
