    Experimental Studies on the Spinal Cord Evoked Potentials in Compression Injury of the Cervical Spinal Cord

    The waveform changes and their recovery processes were analyzed by recording the spinal cord evoked potential (SEP) before, during the after graded cervical ventral compression of the cat spinal cord. The SEP ...

    Experience of Diagnosis of Thoracic Myelopathy Using Spinal Cord Evoked Potentials

    Conducted spinal cord evoked potentials (SEPs) were elicited preoperatively from the thoracic epidural space following spinal cord stimulation in 22 patients with thoracic myelopathy. The waveform changes in S...

    Experimental Studies on the Spinal Cord Evoked Potentials in Cervical Spine Distraction Injuries

    Effects of stepwise distraction of the spinal cord on the spinal cord evoked potentials (SEP) were studied in cats. During the distraction between two adjacent cervical vertebrae, the SEP was examined upon sin...

    Experimental Ascending Evoked Potentials in Spinal Cord Injury

    The basic waveform of the conducted epidural SEP of cat in ascending volleys consisted of two major components, namely N1 and N2, with mean conduction velocity of 74ms and 55ms, respectively. Significant ampli...

    Somatosensory Evoked Potentials in Cervical Myelopathy

    Somatosensory evoked potentials were recorded in 53 patients with cervical myelopathy due to spondylosis (32) or ossification of the posterior longitudinal ligament (21). The overall abnormality rate was 68 pe...
