Study on induction of erection by low-frequency electrical stimulation

我们探讨了一种用低频电刺激诱导勃起的方法，并测量了神经传导时间。首先，将球海绵体诱发肌电图法测定的球-海绵体反射潜伏期时间(bcr-L)与343例阳萎患者的临床结果进行了比较。结果表明，有勃起能力的青年患者的BCR-L延长，而有明显勃起相关神经损伤的患者的BCR-L在正常范围内，提示BCR-L的结果与临床存在差异。因此，我们尝试使用低频电刺激电极来诱导勃起并测量阴茎背神经的传导时间。我们还试图通过硬膜外脊髓电刺激诱导勃起并测量脊神经-阴茎背神经传导时间，将其应用于麻醉学领域的疼痛治疗。S的…更多的对象是阳萎患者，伴随着严重的电击引起的下肢痉挛疼痛和排尿障碍。由于该患者脊神经-背神经传导受损，不能通过电刺激诱导勃起。然而，刺激脊神经改善了腿部痉挛疼痛和排尿障碍。我们计划对这种方法进行修改，以便进一步应用于阳萎的治疗。如上所述，由于这种方法便于通过脊髓刺激来测量阴茎背神经表面电位的变化，所以我们试图通过皮肤低频骶髓电刺激来测量22例阳萎患者阴茎背神经表面电位的变化。结果，在22例患者中，有17例成功地测量到了脊神经表面电位的变化。平均骶背神经传导时间为7.9毫秒，与其他研究人员报道的数据基本一致。本方法被认为是一种易于在门诊使用的最佳方法，因为它使用经皮电刺激，因此是非侵入性的。较少

We investigated a method to induce erection by low-frequency electrical stimulation and measure the nerve conduction time.First, bulbo-cavernosus reflex latency time (BCR-L) determined by bulbocavernosus-evoked electromyography, which is now performed as a neurological test of impotence was compared with the clinical results of 343 patients with impotence. The Results showed that young patients capable of erection had a prolonged BCR-L,while those with apparent injury of the erection-related nerve had a BCR-L within normal limits, clearly indicating a discrepancy between the results of BCR-L and the clinical findings. Therefore, we attempted to induce erection and measure the time of conduction to the dorsal penile nerve using a low frequency electrical stimulating electrode. We also attempted to induce erection and measure the spinal-dorsal penile nerve conduction time by the extradural spinal cord electrical stimulation applied in the field of anesthesiology for pain treatment. The s … More ubject was an impotence patients with spasmodic pain of the lower extremities and urinary disturbance caused by a severe electrical shock. Since this patient had impaired spinal-dorsal nerve conduction, erection could not be induced by electrical stimulation. However, stimulation of the spinal nerve improved spasmodic pain of the lower extremities and urinary disturbance. We are planning to modify thismethod for further application to the treatment of impotence. As stated above, since this method facilitates the measurement of changes in surface potential of the dorsal penile nerve by spinal stimulation, we attempted to measure changes in the surface potential of the dorsal penile nerve by cutaneous low frequency sacral cord electrical stimulation in 22 impotence patients. As a results, change in the surface potential of the dorsal nerve by sacral cord electrical stimulation were successfully measured in 17 out of 22 patients. The mean sacral-dorsal nerve conduction time was 7.9 msec, which almost corresponds to the data reported by other investigators. The present method is concidered to be an optimal method for easy use at the outpatient clinic, because it uses percutaneous electrical stimulation and is, therefore, noninvasive. Less
