报告５０例正常人和３２例单侧型腰椎间盘突出者在刺激节段性（根性）皮神经（腓肠和腓浅）时的腰髓电位（ＬＰ）和皮层电位（ＣＰ），结果发现ＬＰ正确定位２６例（８３％），错定位２例，阴性４例；ＣＰ正确定位１６例（５１％），错定位４例，阴性１２例。
Abstract The lumbar spinal evoked potential (LP) and the cortical somatosensory evoked potential (CP) recorded on the stimulations of segmental (radicular) cutaneous nerves (superficial peroneal and sural)were studied in 32 patients with unilateral lumbar disc protrusion and 50 normal volunteers. It was noted that correct localization of the lesion was found in 26 cases (83%) , incorrect localization in 2, and normal in 4 in LP examination while the correct localization in 16. incorrect in 4, and normal in 12 in CP examination.
