The American Society of Neurophysiological Monitoring

The ASNM History

The American Society of Neurophysiological Monitoring was founded in 1990 to serve the emerging field of neurophysiologic monitoring. As defined by the Society, neurophysiologic monitoring includes any measure employed to assess the ongoing functional integrity of the central or peripheral nervous system in the operating theatre or other acute care setting.

Intraoperative neurophysiological monitoring (IONM) has evolved over the last several decades. Its mission is protection of the patient’s nervous system. Neurophysiologic signals are monitored continuously during surgery for adverse changes, detection of which enables corrective action. Risk of postoperative neurological deficit, such as weakness, loss of sensation, hearing loss and impairment of other bodily functions is thereby reduced. In addition to detection of change, surgical guidance can be offered in specialized circumstances.

Our Vision

The Society serves as the leading organization for the field of interventional neurophysiological assessment and monitoring.
