About Intraoperative Neurophysiology

Intraoperative neurophysiology (ION), also known as intraoperative neuromonitoring, Intraoperative  neurophysiologic monitoring (IONM) or neurophysiologic intraoperative monitoring (NIOM),  employs electrophysiologic techniques that, when performed accurately, can reliably  "visualize" the function of various nervous structures during surgeries such as brain, spine, vascular or cardiac  procedures.

By utilizing dependable ION procedures, critical parts of the nervous system that are at risk of injury during surgery, can be identified, mapped (neurophysiologic mapping), and continuously monitored (neurophysiologic monitoring)  to detect early, reversible dysfunction. Further, real-time ION information  needs to be delivered in a timely fashion and integrated within the multidisciplinary care in the operating room. This enables surgical and anesthesia teams to make swift adjustments, helping to prevent permanent neurological damage. Ultimately, ION can reduce the risk of severe postoperative deficits, including impairments in motor or sensory functions, bowel control, walking, speech, vision, hearing, swallowing or breathing.

​

Our Mission​​

We are committed to empowering patients and healthcare providers with essential information about reliable ION procedures and processes —underscoring their important role in preventing neurological complications during a wide range of surgeries. Our goal is to support informed decisions and promote highest standards of safety for surgical patients.
