Multimodality monitoring of the central nervous system using motor-evoked potentials

This review was conducted to examine the role of motor-evoked potential monitoring in spine and central nervous system surgery to determine whether other monitoring modalities such as the wake-up test or somatosensory-evoked potentials can be eliminated. The current literature suggests that motor-evoked potential, despite some advantages, still requires that other monitoring modalities such as somatosensory-evoked potentials or electromyography be used to provide optimal monitoring. The literature supports the use of multimodality monitoring using all of the electrophysiological techniques that can provide intraoperative information about the neural structures at risk during the surgery.
