Intraoperative neuromonitoring is important because it allows a trained technician to identify a change in the electric signals radiating from targeted central and peripheral nervous system structures (your brain, spinal cord, or nerves in your arms and legs). A change in a patient’s electric signals can indicate a possible injury to the nervous system. When these changes are identified in a timely manner, the surgical team can take appropriate steps to minimize or eliminate any potential permanent injury to the patient’s nervous system.
