Abstract
The purpose of the study was to work out the methods for somatosensory evoked potentials registration under conditions of nerve paths injury in experiment. Evoked potentials were recorded in laboratory animals divided into 5 groups according to the volume of injury inflicted by the technique worked through previously. Potentials were recorded prior to intervention and on 1st, 7th, 14th, 21st, 30th and 45th postoperative day. On the 1st day sharp decrease of potential amplitudes was observed in groups with incomplete spinal cord injury. In groups with complete spinal cord injury no potentials were recorded. Slight restoration of nerve conductivity was observed only in rats with 50% spinal cord transection. Study results showed the efficacy of the technique in the assessment of spinal cord tissues conductivity and confirmed the absence of spontaneous nerve paths restoration after more than 50% of spinal cord transection.
