This report describes the waveform and properties of somatosensory evoked potentials recorded from various levels of the human spinal cord, with electrodes inserted into the epidural space and the stimulus delivered to the posterior tibial nerve at the knee. The object was to provide a means of monitoring spinal cord function during surgery for the correction of spinal deformities. The responses could be resolved into at least three components with different activation thresholds and different conduction velocities within the spinal cord (45-80 m/s approximately). The findings are in accord with recent studies, suggesting that the fast activity may be conducted in the dorsal spinocerebellar tract and the slower waves in the posterior columns.
本报告描述了从人类脊髓不同水平记录的体感诱发电位的波形和特性,电极插入硬膜外间隙,刺激施加于膝部的胫后神经。目的是提供一种在脊柱畸形矫正手术中监测脊髓功能的方法。这些反应可分解为至少三个成分,在脊髓内具有不同的激活阈值和不同的传导速度(约45 - 80米/秒)。这些发现与最近的研究一致,表明快速活动可能在脊髓背侧小脑束中传导,较慢的波在脊髓后柱中传导。
