Neurophysiological Monitoring:


Intraoperative Neurophysiological Monitoring is a series of tests that are performed while you are anesthetized during your surgery. It studies the electrical activity of the brain and nervous system. These tests are performed on your behalf as they assess the integrity of your brain, spinal cord, and nerves as they leave the spinal cord. We perform anywhere from 3 to 5 tests throughout your surgery to monitor your nervous system.

All of this occurs when you are fully asleep.

Just as you would expect the anesthesiologist to monitor your heart during your surgery, intraoperative monitoring assesses your nerves, spinal cord and brain. This allows the surgeon to be notified if there is a problem while the operation is occurring, rather than after, when you wake up.

Intraoperative monitoring involves more than just neural monitoring technologists running neurodiagnostic equipment. It must involve critical human judgment of the monitored information. The surgeons we work with have confidence in our neural monitoring technologists because they are knowledgeable and provide accurate information.

 The following are some of the types of monitoring tests that we perform during surgery:


· Somatosensory Evoked Potentials

· Motor Evoked Potentials


· Brainstem Auditory Evoked Potentials

· Electroencephalography

· Pedicle Screw Testing
