Neuromonitoring (IONM)

A compact guide to intraoperative neuromonitoring for spine surgeons, anaesthetists and neurophysiology teams.

14 guidelines · 9 system makers · checked October 2026

Intraoperative neurophysiological monitoring (IONM) in spine surgery: the societies, how monitoring staff are trained and certified, the main guidelines, who may monitor in different countries, and an A–Z of system makers.

Guidelines and position statements

Who may monitor: country rules

USA

There is no single national licence for IONM; ASNM guidance treats the professional (interpretive) level as the practice of medicine and asks the supervising professional to meet state licensure and hospital privileging rules, while technologists typically hold ABRET's CNIM. Requirements differ by state and by payer.

Source →Source checked

UK

No statutory rule specific to IONM was found; national ANS/BSCN guidance says monitoring should be done by trained, competent medical and physiological staff, with clinical interpretation linked to consultant-level neurophysiologists or consultant scientists.

Source →Source checked

Germany

No specific statutory rule on who may perform or interpret IONM was found; the DGKN offers a voluntary IONM certificate open to physicians, other medical staff and science graduates, and general German delegation principles for medical tasks apply.

Switzerland

No official IONM-specific rule or FMH/SIWF certificate was found; the SGKN runs competency programmes only for EEG, ENMG and cerebrovascular sonography, and IONM training is offered through courses such as those of the SFND.

How we compile this page

Guidelines differ: the AANS/CNS guideline (2017) does not regard monitoring as a standard of care for all spine surgery, while the AO Spine guideline (2024) recommends it for high-risk procedures. We link both and do not take sides. The makers list is alphabetical and neutral; inclusion is not a recommendation. Recalls of monitoring equipment appear in Regulatory Watch; new systems in Product Developments. See also Spine Anaesthesia.
