摘　　要：本文对69例健康男性阴部皮层、阴部骶髓体感诱发电位(SEPs)。生殖皮层及生殖骶髓运动诱发电位(MEPs)以及骶髓反射时(SRL)进行了综合研究。结果表明,电刺激阴茎背神经时感觉传导总时间为59.18±1.92ms;外周感觉传异时间为9.98±1.30ms;中枢感觉传导时间为29.66±2.32ms;跨颅磁刺激及骶脊神经根磁剌激时运动传导总时间为20.34±2.28ms;外周运动传导时间为6.05±1.40ms;中枢运动传导时间为14.31±2.68ms,骶髓反射时为35.15±3.58ms。此外,本文还对阴部神经诱发电位检测的意义及临床应用方面的有关问题进行了讨论。Extensive neurophysiolorcal investigations were caried out in 69 healthy male subjects.THe test consisted of cortical pudendal and spinal pudendal evoked potentials (SEPs)to stimulation of dorsal nerve of penis,cortical and spinal motor evoked potentials(MEPs) form the bulbocavernosus muscles (BC) in response to scalp and sacral root stimulation,the measurement of sacral reflex latency (SRL) form anal sphincter. The mean sensory total conduction time as measured at the peak of scalp P1 wave was 39.18± 1.92 ms.The mean sensory prepheral conduction time was 9.98±1.30 ms.The mean sensory cen- tral conduction time was 29.66±2.32 ms. Transcranial brain stimulation was performed by using a magnetic stimulator during voluntary conduction of the examed muscles.Motor total conduction time to anal sphincter muscles was 20.34 ±2.28 ms.Motor prepheral conduction time was 6.03±1.40 ms.Motor central conduction time was 14.31±2.68 ms.The mean latency of SRL was 35.15±3.58 ms. Combined or isolated abnormalities of SEPs,MEPs and SRL were found in some patients with impotence.
