Who are ENPs?

To have a better understanding of who ENPs are, we reached out to our partners in the Canadian Association of Electroneurophysiology Technologists (CAET) and the Canadian Board of Registration of Electroencephalograph Technologists (CBRET) for an overview.(click here for details)

Electroneurophysiology Technologists (ENP) perform electroencephalograms (EEG) and/or evoked potential examinations. During an EEG, the electrical activity of the brain is recorded by placing small discs (electrodes) on the patient’s head. An EEG can be done when the patient is awake or asleep, depending on why the test is being done. EEGs may be ordered to help diagnose various problems with the brain. Some examples are:

  • seizures and epilepsy
  • strokes and bleeding in the brain
  • degenerative brain disease
  • brain infections

Evoked potential (EP) testing records the electrical activity of the brain and spinal cord after a deliberate external stimulation (such as a noise in the ear or watching a pattern on a TV screen). The visual (eyes), auditory (ears), motor (muscle) and sensory nerves can all be tested for such things as:

  • spinal cord injuries
  • tumours on the nerves
  • inflammation of the nerves

Because EPs can look at a variety of neurological pathways, they are sometimes done in the operating room to provide information to the surgeons as they operate. This way the surgeons can change the way they are operating if they need to, depending on the monitoring results.
