Perianal electrical stimulation induces reflex activity in the superficial part of the external anal sphincter muscle. Several components of differing latency can be recognised. It is suggested that these correspond with the ripples of contraction observed clinically after perianal scratch stimuli. Some of our earlier studies suggested an erroneously short latency for the first component of this cutaneously-elicited reflex. The reasons for this are discussed.
肛周电刺激可诱发肛门外括约肌浅层的反射活动。可以识别出潜伏期不同的几个成分。有人认为,这些成分与临床上肛周搔抓刺激后观察到的收缩波动相对应。我们早期的一些研究表明,这种皮肤诱发反射的第一个成分的潜伏期错误地缩短了。本文讨论了其原因。
