Responses in the external anal and urethral sphincters as well as in the bulbocavernosus muscle have been evoked by supramaximal electrical stimulation of the penis (or clitoris), perineum and the peri-anal region and recorded electromyographically in 82 male subjects 5 to 73 years old and in nine female subjects 18 to 55 years old, who had no systemic diseases or demonstrable sacral nervous system lesion. On perineal stimulation (including the penis or clitoris) reflex responses with a typical latency of 33 ms and which exhibit no habituation were obtained in all muscles examined. Stimulation of the peri-anal region gave habituating reflex responses with a typical latency of 55 ms in all muscles examined. On perineal, and sometimes also peri-anal stimulation, stable short latency responses with typical latencies of 5 and 13 ms were recorded; both were considered to be direct responses. The different evoked muscle responses obtained by stimulation in the perineal and peri-anal region have to be distinguished when the bulbocavernosus and anal reflexes are recorded for evaluation of sacral nervous system lesions.
通过对阴茎（或阴蒂）、会阴和肛门周围区域进行超强电刺激，诱发了82名年龄在5至73岁的男性受试者以及9名年龄在18至55岁的女性受试者的肛门外括约肌、尿道括约肌和球海绵体肌的反应，并通过肌电图进行记录。这些受试者无全身性疾病或明显的骶神经系统病变。在会阴刺激（包括阴茎或阴蒂）时，在所有检查的肌肉中均获得了典型潜伏期为33毫秒且无习惯化现象的反射反应。刺激肛门周围区域时，在所有检查的肌肉中均获得了潜伏期为55毫秒的习惯化反射反应。在会阴刺激（有时也包括肛门周围刺激）时，记录到了潜伏期分别为5毫秒和13毫秒的稳定短潜伏期反应；两者均被认为是直接反应。在记录球海绵体反射和肛门反射以评估骶神经系统病变时，必须区分在会阴和肛门周围区域刺激所获得的不同诱发肌肉反应。
