The bulbocavernosus reflex may be evoked electrically with a latency of approximately 35 msec. in normal male subjects. We have studied the sacral-evoked response in 116 individuals, 10 of whom were normal controls. For each study ipsilateral and contralateral responses were obtained from each side, resulting in 4 latency values. We herein describe the abnormalities in 54 patients with a variety of documented neurologic lesions. Our investigation reveals that the bulbocavernosus reflex has the characteristics of a cutaneous polysynaptic bilateral flexor response. The use of bilateral stimulation and recording techniques permits more effective localization of neurologic lesions involving the conus medullaris or cauda equina roots.
在正常男性受试者中,球海绵体反射可通过电刺激诱发,潜伏期约为35毫秒。我们对116名个体进行了骶部诱发反应研究,其中10名是正常对照。每次研究时,从每侧获得同侧和对侧反应,从而得到4个潜伏期值。我们在此描述了54例有各种已记录神经病变患者的异常情况。我们的研究表明,球海绵体反射具有皮肤多突触双侧屈肌反应的特征。使用双侧刺激和记录技术可以更有效地定位涉及脊髓圆锥或马尾神经根的神经病变。
