根据简短的记录，直肠收缩的频率为每分钟5到10个周期，缓慢收缩的频率为每分钟3个周期。为了确定肛门直肠运动在一个较长的时间内，我们研究了12名健康志愿者使用精细的压敏肛门直肠探头。总共获得了240小时的记录。我们在直肠中观察到三种类型的活动：（i）频率为每分钟2至3次的强有力的阶段性收缩，持续3至10分钟，并以92（1.9）分钟（平均值（SEM））和56（1.7）分钟（平均值（SEM）），（ii）持续10-20秒的孤立性长时间收缩，主要在清醒时观察到，和（iii）以每分钟5 - 6次的频率发生的收缩簇，持续1 - 2分钟，并且主要在餐后期间观察到。这些收缩簇类似于在回肠中观察到的离散簇收缩，而更有力和更长时间的收缩类似于小肠中的III期活动。相反，肛管显示出与时间无关的收缩爆发。我们的数据表明，直肠，像上消化道，表现出周期性的运动活动，这两个生物节律是否同步还有待观察。
Based on short recordings, the rectum has been shown to have contractions with a frequency of five to 10 cycles per minute and slow contractions at three cycles per minute. To define anorectal motility over a prolonged period of time, we have studied 12 healthy volunteers using a fine pressure sensitive anorectal probe. A total of 240 hours of recording was obtained. We observed three types of activity in the rectum: (i) runs of powerful phasic contractions with a frequency of two to three per minute, lasting for three to 10 minutes, and recurring to an interval of 92 (1.9) minutes (mean (SEM)) during the day and 56 (1.7) minutes (mean (SEM)) at night, (ii) isolated prolonged contractions lasting for 10-20 seconds and seen mainly during waking, and (iii) clusters of contractions occurring at a frequency of five to six per minute lasting for one to two minutes and seen predominantly during the postprandial period. These clusters of contractions resembled the discrete clustered contractions seen in the ileum, whereas the more powerful and prolonged runs of contractions resembled phase III activity in the small intestine. In contrast, the anal canal showed bursts of contractions which were not temporally related. Our data show that the rectum, like the upper gastrointestinal tract, exhibits periodic motor activity; it remains to be seen whether these two biorhythms are synchronous.
