Somatosensory evoked potentials (S.E.P.) were used to examine twelve patients who had slow compressive lesions of the spinal cord (ten cases of spondylotic myelopathy, one neurinoma, one metastasis of a vertebral body). 73 per cent of the recordings were found to be abnormally reduced in amplitude, and/or showed prolonged latency times aa regards the primary and secondary complex. Patients with a clinical lesion of the dorsal column showed a clear reduction in amplitude in the recordings (sometimes coupled with slowed latency), especially in the primary complex. Patients with symptoms indicative of an injury to the ventrolateral region of the spinal cord showed tracings with alterations most of all related to the secondary complex. In 76 per cent of cases, the somatosensory evoked potentials were in accordance with the level of the compression, the degree of invalidity, and the clinical picture.
体感诱发电位（S.E.P.）用于检查12例患有脊髓缓慢压迫性病变的患者（10例脊髓型颈椎病、1例神经鞘瘤、1例椎体转移瘤）。结果发现，73%的记录在振幅上异常降低，和/或在初级和次级复合波方面显示出潜伏期延长。有后柱临床病变的患者在记录中显示出明显的振幅降低（有时伴有潜伏期延长），尤其是在初级复合波中。有脊髓腹外侧区域损伤症状的患者显示的描记图变化主要与次级复合波有关。在76%的病例中，体感诱发电位与压迫水平、残疾程度和临床表现相符。
