Extensive neurophysiological investigations were carried out in 100 healthy subjects and 84 patients with penile erectile dysfunction.
Following examinations were performed, spinal and scalp somatosensory evoked potentials (SEPs) to stimulation of the dorsal nerve of penis, motor evoked potentials (MEPs) from bulbocavernosus (BC) in response to scalp and spinal root stimulation, and measurement of sacral reflex latency (SRL) from anal sphincter (AS).
In the healthy subjects, the mean sensory total conduction time (sensory TCT), as measured at the peak of the scalp P1 (P40) wave was 39.73 ms. The mean sensory central conduction time (sensory CCT = spinal-to-scalp conduction time) was 28.98 ms. The mean peripheral conduction time (PCP) was 9.40 ms. Transcranial brain stimulation was performed by using a magnetic stimulator during voluntary contraction of the examined muscle. Spinal root stimulation was performed at rest. Motor total conduction time (motor TCT) to BC muscles was 20.48 ms. Motor central conduction time (motor CCT) to sacral cord segments controlling BC muscles was 14.42 ms at rest. The mean SRL was 35.13 ms.
Combined or isolated abnormalities of SEPs, MEPs, and SRL were found in patients with erectile dysfunction.
对100名健康受试者和84名阴茎勃起功能障碍患者进行了广泛的神经生理学研究。
进行了以下检查，对阴茎背神经刺激的脊髓和头皮体感诱发电位（SEPs）、对头皮和脊髓神经根刺激的球海绵体肌（BC）运动诱发电位（MEPs）以及肛门括约肌（AS）的骶反射潜伏期（SRL）测量。
在健康受试者中，在头皮P1（P40）波峰值处测量的平均感觉总传导时间（感觉TCT）为39.73毫秒。平均感觉中枢传导时间（感觉CCT = 脊髓至头皮传导时间）为28.98毫秒。平均外周传导时间（PCP）为9.40毫秒。在被检查肌肉自主收缩期间使用磁刺激器进行经颅脑刺激。在休息时进行脊髓神经根刺激。BC肌肉的运动总传导时间（运动TCT）为20.48毫秒。休息时，控制BC肌肉的骶髓节段的运动中枢传导时间（运动CCT）为14.42毫秒。平均SRL为35.13毫秒。
在勃起功能障碍患者中发现了SEP、MEP和SRL的联合或单独异常。
