What is Intraoperative Neuromonitoring?
Intraoperative Neuromonitoring (IONM), or Surgical Neuromonitoring, assists surgeons in locating and protecting nerves, the spinal cord, and the brain during surgical procedures. It has been clinically proven to reduce the patient’s risk of damage to the nervous system. Intraoperative neuromonitoring can also be used to locate and test the function of neural structures.
IONM is performed by a certified Surgical Neurophysiologist in the operating room and is overseen remotely in real-time by a Neurologist. Together, they evaluate and interpret data and communicate to the surgical team information needed to safeguard patient safety and ensure positive surgical outcomes.

- Electromyography (EMG)
- Free Run Electromyography (fEMG)
- Triggered Electromyography (tEMG)
- Direct Nerve Stimulation
- Electroencephalogram (EEG)
- Sensorimotor Cortex Localization
- Motor Mapping
- Language Mapping
- Dorsal Column mapping
- Saphenous SSEP
- Collision Studies
Every surgery will be supported by a licensed neurologist, credentialed in the hospital where services are provided, who will serve to interpret the real-time data. This will be achieved through a secure, HIPAA-compliant internet connection established by the AMS technologist in the OR. The Interpreting Physician (IP) and technologist will be in communication before surgery begins and continually during the case. This allows for dialogue and alerts with recommendations for medical intervention if changes in test results should occur.
Oversight Is Best Practice
CMS guidelines require that data be interpreted by a physician real-time. If there is not an Interpreting Physician, the hospital and surgeon may become liable for not providing standard of care. The surgeon becomes liable for oversight of the technologist.
