The proper evaluation of the pelvic floor muscles (PFM) is essential for choosing the correct treatment. Currently, there is no gold standard for the assessment of female PFM function.
To determine the correlation between vaginal palpation, vaginal squeeze pressure, and electromyographic and ultrasonographic variables of the female PFM.
This cross-sectional study evaluated 80 women between 18 and 35 years of age who were nulliparous and had no pelvic floor dysfunction. PFM function was assessed based on digital palpation, vaginal squeeze pressure, electromyographic activity, bilateral diameter of the bulbocavernosus muscles and the amount of bladder neck movement during voluntary PFM contraction using transperineal bi-dimensional ultrasound. The Pearson correlation was used for statistical analysis (p<0.05).
There was a strong positive correlation between PFM function and PFM contraction pressure (0.90). In addition, there was a moderate positive correlation between these two variables and PFM electromyographic activity (0.59 and 0.63, respectively) and movement of the bladder neck in relation to the pubic symphysis (0.51 and 0.60, respectively).
This study showed that there was a correlation between vaginal palpation, vaginal squeeze pressure, and electromyographic and ultrasonographic variables of the PFM in nulliparous women. The strong correlation between digital palpation and PFM contraction pressure indicated that perineometry could easily be replaced by PFM digital palpation in the absence of equipment.
正确评估盆底肌肉（PFM）对于选择正确的治疗方法至关重要。目前，女性PFM功能评估尚无金标准。
确定女性PFM的阴道触诊、阴道挤压压力与肌电图及超声检查变量之间的相关性。
这项横断面研究评估了80名年龄在18至35岁之间、未生育且无盆底功能障碍的女性。通过经会阴二维超声，基于指诊、阴道挤压压力、肌电活动、球海绵体肌双侧直径以及自主PFM收缩期间膀胱颈移动量来评估PFM功能。采用Pearson相关性进行统计分析（p<0.05）。
PFM功能与PFM收缩压力之间存在强正相关（0.90）。此外，这两个变量与PFM肌电活动（分别为0.59和0.63）以及膀胱颈相对于耻骨联合的移动（分别为0.51和0.60）之间存在中度正相关。
本研究表明，未生育女性的PFM阴道触诊、阴道挤压压力与肌电图及超声检查变量之间存在相关性。指诊与PFM收缩压力之间的强相关性表明，在没有设备的情况下，会阴压力测量法很容易被PFM指诊所取代。
