What factors influence the intraoperative variability of somatosensory cortical evoked potentials during spinal surgery?
The variability of somatosensory cortical evoked potentials during spinal surgery is highly dependent on patient diagnosis and neuromuscular status, which may limit its reliability in detecting early cord compromise in certain populations.
Lubicky et al. (1989) studied this question.
