Anorectal function is known to be influenced by age but there is only scanty information about the effect of ageing on pelvic floor dynamics. Pelvic floor movements were assessed by videoproctography in two groups of ten control females (mean age of 30.5 and 60.7 years, respectively). A significantly lower pelvic floor position was found at rest in the older group (p = 0.02), but younger controls showed an increased pelvic floor descent during straining (p = 0.01). These results suggest that the pelvic floor is affected by progressive denervation but descent during straining tends to decrease with advancing age.
已知肛门直肠功能受年龄影响，但关于衰老对盆底动力学影响的信息却很少。通过视频直肠造影术对两组各10名对照女性（平均年龄分别为30.5岁和60.7岁）的盆底运动进行了评估。在老年组中，静息时盆底位置明显较低（p = 0.02），但年轻对照组在用力排便时盆底下降增加（p = 0.01）。这些结果表明，盆底受进行性去神经支配的影响，但随着年龄的增长，用力排便时的下降趋势趋于减少。
