Detailed Description
This is a cross-sectional survey. The normal physical examination population is divided into three groups,including premenopausal nullipara, premenopausal women with childbirth and postmenopausal women. The pelvic floor muscle function in three groups are evaluated. The modified Oxford Grading Scale and Levator ani testing is used to quantify PFM strength through vaginal palpation. Pelvic floor muscle strength ,endurance, repetition,vaginal contraction pressure and the knack test are evaluated using a PHENIX USB 8 neuromuscular stimulation therapy system (Company: Vivaltis-Electronic Concept Lignon Innovation, Montpellier, France). In six different regions of China according to geographic region (northwest, southwest, north, east, northeast, and central-south China) , 1 or more hospitals in each area are selected as sub-centers, which needs to complete the evaluation of pelvic floor muscle function of 360 cases in 3 groups totally.

Outcome Measures
Primary Outcome Measures
- maximum vaginal contraction pressure [1 day]
it is measured by manometry, range(80-150cmH2O). The higher values represent better outcomes.
Secondary Outcome Measures
- Pelvic floor muscle strength [1 day]
The modified Oxford Grading Scale is used to quantify PFM strength through vaginal palpation. range(0-5).The higher values represent better outcomes. through vaginal palpation.
- Pelvic floor muscle strength（repetition） [1 day]
Levator ani testing is used to quantify PFM strength. range(0-5). The higher values represent better outcomes.
- Pelvic floor muscle contraction endurance [1 day]
muscle contractions maintained for 0 s are defined as grade 0, 1 s as grade I, 2 s as grade II, 3 s as grade III, 4 s as grade IV, and 5 s or longer as grade V. Normal muscles can maintain the contraction for 5 s. range(0-5s). The higher values represent better outcomes.
- pelvic organ prolapse quantification [1 day]
POP-Q is measured when maximum valsalva. range(0-4). stage 0 represents normal.
- the knack test [1 day]
a voluntary PFM contraction before or during coughing. That the contraction could be performed represents normal.
- vaginal rest pressure [1 day]
measure when no vaginal contraction by manometry. range(25-50 cmH2O). the lower and the higher values represent abnormal outcomes.
