Abstract

Recordings of somatosensory evoked potentials (SEPs) and SEP brain maps of 23 patients with vertebral injury were analyzed. All patients were operated at the Clinic of Military Traumatology and Orthopedics, Military Medical Academy. SEPs (19 sites) were recorded in real time and mapped with "Brain surveyor" neuromapper. Brain lesions were localized before surgery by of MR imaging and CT standard techniques. The results demonstrate that electrical stimulation of peripheral nerves produces a substantially variable SEP pattern. It was shown that SEP formation in more than 60% of recordings suggests a favorable prognosis for rehabilitation, whereas if more than 50% of recording sites are unresponsive, the rehabilitation prognosis is unfavorable. The amplitude of early components (below 60 ms) increases, and that of the late waves reduces.
