Pelvic floor muscle (PFM) strength is a critical factor for optimal pelvic floor function. Fluctuations in strength values based on different phases of the menstrual cycle (MC) could signify a need for a paradigm shift in evaluating, approaching, and planning training. This research aims to examine and contrast the pelvic floor muscle strength during different phases of the menstrual cycle. A prospective observational study employing digital assessment with the modified Oxford scale and vaginal dynamometry measurements was performed, in order to assess the baseline strength and the contraction strength of the PFMs in eumenorrheic females at three different phases of the MC: the early follicular phase (EFP), the late follicular phase (LFP), and the mid-luteal phase (MLP). During two complete cycles, tympanic temperature and body weight were measured and the urinary luteinizing hormone concentration was tested to determine the time of ovulation. In total, 216 dynamometric measurements of PFM strength were obtained from eighteen nulliparous women (25.72 ± 5.03 years). There were no differences between the baseline strength ( = 0.886) and the contraction strength ( = 0.756) with the dynamometric speculum. In the post hoc analysis, the baseline strength, contraction strength, and strength showed no significant differences between MC phases. As no differences in PFM strength in women were found, the PFMs do not seem to be weaker at any time during the menstrual cycle. It appears that the assessment, establishment, and monitoring of a PFM training program could be initiated at any point in the cycle.
盆底肌肉（PFM）力量是盆底功能达到最佳状态的关键因素。基于月经周期（MC）不同阶段的力量值波动可能意味着在评估、处理和规划训练方面需要进行范式转变。本研究旨在检查和对比月经周期不同阶段的盆底肌肉力量。进行了一项前瞻性观察研究，采用改良牛津量表进行数字评估和阴道测力计测量，以评估月经规律女性在月经周期的三个不同阶段：卵泡早期（EFP）、卵泡晚期（LFP）和黄体中期（MLP）时盆底肌肉的基线力量和收缩力量。在两个完整周期内，测量鼓膜温度和体重，并检测尿促黄体生成素浓度以确定排卵时间。总共从18名未生育女性（25.72±5.03岁）获得了216次盆底肌肉力量的测力计测量值。使用测力计窥器时，基线力量（P = 0.886）和收缩力量（P = 0.756）之间没有差异。在事后分析中，月经周期各阶段之间的基线力量、收缩力量和力量均无显著差异。由于未发现女性盆底肌肉力量存在差异，因此盆底肌肉在月经周期的任何时候似乎都不会更弱。看来，盆底肌肉训练计划的评估、制定和监测可以在月经周期的任何时间开始。
