Abstract
Conductive and segmental evoked spinal cord potentials (ESCPs) have been employed since 1982 as a monitor during cervical anterior decompression surgery [3]. Conductive ESCPs, showing the function of the lower extremities, are recorded from the cervical epidural space following stimulation of the thoracic spinnal cord, and segmental ESCPs are elicited by stimulating the median nerve to evaluate the function of the upper extremities. However, it is difficult to monitor motor dysfunction of the upper extremities using these ESCPs during surgery. We confirmed that a potential that descends the spinal cord and passes through the anterior roots is contained in the potential recorded from the median nerve after stimulating the upper cervical spinal cord. Calling this potential the descending segmental evoked spinal cord potential (DS-ESCP), we conducted a study on identification of the origin and conduction route of this potential and its usefulness as a monitor for motor function of the spinal cord.
