Although aging is considered a risk factor for pelvic floor muscle dysfunction (PFMD), the effect of aging on the function of the pelvic floor muscles (PFM) remains unclear.
To compare PFM function and activity in nulliparous women in different age groups.
This was a cross-sectional study in which 70 women with ages between 18 and 69 years were divided into five age groups for evaluation. Initially, medical histories were taken, and then the PFM function was assessed using digital palpation (Modified Oxford Scale), manometry and surface electromyography (sEMG). The Kruskal-Wallis test was applied to check the differences between the groups. The Spearman correlation coefficient was used to verify the correlations between age and PFM function, manometry values and sEMG. A significance level of 5% was adopted.
No significant differences were observed between the different age groups in PFM digital palpation, manometry values and sEMG. There was a low negative correlation between age root mean square and peak of sEMG signals.
This study found no difference in PFM function and activity between nulliparous women in the five different age groups. Future long-term large prospective studies are required to confirm these findings.
尽管衰老被认为是盆底肌肉功能障碍（PFMD）的一个风险因素，但衰老对盆底肌肉（PFM）功能的影响仍不清楚。
比较不同年龄组未生育女性的盆底肌肉功能和活动情况。
这是一项横断面研究，将70名年龄在18至69岁之间的女性分为五个年龄组进行评估。首先，采集病史，然后使用指诊（改良牛津量表）、压力测定法和表面肌电图（sEMG）评估盆底肌肉功能。应用Kruskal-Wallis检验来检查各组之间的差异。使用Spearman相关系数来验证年龄与盆底肌肉功能、压力测定值和表面肌电图之间的相关性。采用5%的显著性水平。
不同年龄组在盆底肌肉指诊、压力测定值和表面肌电图方面未观察到显著差异。年龄与表面肌电图信号的均方根和峰值之间存在低负相关性。
本研究发现五个不同年龄组的未生育女性在盆底肌肉功能和活动方面没有差异。未来需要进行长期的大型前瞻性研究来证实这些发现。
