To compare pelvic floor muscle strength in nulliparous sports students measured using the modified Oxford Grading Scale and a Peritron manometer; and to compare the manometric measurements between continent and incontinent subjects.
Cross-sectional study. All subjects were evaluated twice on the same day; first by vaginal digital examination and subsequently by vaginal pressure using a Peritron manometer.
Forty-three nulliparous female sports students [mean age 21 (standard deviation 4) years] from the Sports Faculty of the University of Porto.
This study found a significant moderate correlation between the Oxford Grading Scale score and peak pressure on manometry (r=0.646, P=0.002). Mean maximal strength for the entire group was 70.4cmH2O (range 21 to 115cmH2O). Out of 43 subjects, 37% (n=16) demonstrated signs of incontinence. On manometry, no significant differences were found in vaginal resting pressure or peak pressure between the continent and incontinent groups.
There was moderate correlation between peak pressure on manometry and the Oxford Grading Scale score. Peritron manometer measurements of pelvic floor muscle contractions showed no significant differences in vaginal resting pressure and peak pressure in continent and incontinent subjects.
比较使用改良牛津分级量表和 Peritron 压力计测量的未生育运动学生的盆底肌力量；并比较 continent 和 incontinent 受试者的压力计测量值。
横断面研究。所有受试者均在同一天接受两次评估；首先通过阴道数字检查，然后通过阴道压力使用 Peritron 压力计进行检查。
来自波尔图大学体育学院的 43 名未生育的女性运动学生[平均年龄 21（标准差 4）岁]。
本研究发现改良牛津分级量表评分与压力计上的峰值压力之间存在显著中度相关性（r=0.646，P=0.002）。整个组的平均最大强度为 70.4cmH2O（范围 21 至 115cmH2O）。在 43 名受试者中，37%（n=16）出现失禁迹象。在压力计上，continent 和 incontinent 组之间的阴道静息压力或峰值压力无显著差异。
