Abstract

In this study five volunteers with special training in anal sphincter exercise (Scandinavian Yoga School) managed voluntarily to reduce anal pressure. The mean reduction of anal pressure was 20 mm Hg. In one of the subjects, this was shown by manometry during low spinal anesthesia and electromyography to be caused by relaxation of the external anal sphincter.

摘要

在本研究中，五名接受过肛门括约肌锻炼专项训练（斯堪的纳维亚瑜伽学校）的志愿者成功自主降低了肛门压力。肛门压力平均降低了20毫米汞柱。在其中一名受试者身上，通过低位脊髓麻醉期间的测压法和肌电图显示，这是由肛门外括约肌松弛引起的。
