Intraoperative monitoring of the spinal cord involves monitoring of somatosensory evoked potentials and motor evoked potentials. The guideline found that in all cases where paralysis occurred, the patients had changes in their evoked potentials during the surgery, while there were no cases of paralysis in patients without any changes in their evoked potentials.
The guideline was developed with the American Clinical Neurophysiology Society and is published in the February issue of Neurology.
