Abstract

Using somatosensory evoked potential response(SEP) we try to evaluate spinal cord injuries in patients. Recording of the SEP in patients with spinal cord injury is carried out at bed side in the hospital room with a mobile cart containing the EEG amplifiers, averaging computer, oscilloscope and camera. For recording the SEP with deep peroneal or median nerve stimulation, records are made using electrode position C4 and C3 of international 10-20 system. In our work we have average 256 response with the peripheral nerve being stimulated at a frequency of one per second. Stimulation is carried out with square wave pulses of 0.1 msec in duration. The recording characteristics of the Sanei 7SO7 amplifier are used our preliminary data from the study fo 16 patients with spinal cord injuries show that the evoked potential study is an extremely sensitive indicator of spinal cord damage. It may prove particulaly useful in the early identification of incomplete spinal lesions and it show promise in developing into a useful method.
