Brief summary
The purpose of this study is to explore the correlation between women's pelvic floor function with their overall state of bodily functions, including body composition, physical activity levels, trunk muscle endurance, body posture, vaginal and gut microbes. The main intervention of this study is a set of global training which Includes the strength, endurance, flexibility, stability and flexibility training on the diaphragm, abdominal, lower back, as well as pelvic floor muscles, on the basis Kegel training. The primary destination of global training is to shorten the cycle of postpartum pelvic floor functional recovery, improve the effect of maternal training, and convenient in clinical promotion.
Detailed description
Training for 2 times a week, for 12 weeks leading by a specific physiotherapist.The training intensity was evaluated by RPE self-induced fatigue scale.
Interventions
BEHAVIORALActive Comparator: Routine education group
Behavior guidance on pelvic floor muscle function training , including Knack method education , and Kegel exercise and other pelvic floor muscle training methods were taught to postpartum women.
BEHAVIORALExperimental: Global training group
Global training was added on the basis of control group. The 30min-training plan is divided into 9 sections, of which, groups 1 to 8, each group takes about 3 minutes, the ninth group is cool down section, including stretching for 5 minutes and foam axis stretching for 1 minute.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline pelvic floor muscle strength at 6 months or after 12 weeks training | Baseline; After 12 week training or 6th month postpartum | The participants were instructed to contract the pelvic floor muscle correctly and allowed for one practice. Three times of maximum contraction holding for five seconds with an interval resting of five seconds were performed, and the maximum value among three was recorded as the muscle strength of maximal voluntary contraction. The result was recorded using the modified Oxford Grading scale, ranging from 0 to 5, which 0 represents no discernible pelvic floor muscle contraction and 5 represents a strong pelvic floor muscle contracion. |
| Change from Baseline pelvic floor electrophysiology at 6 months or after 12 weeks training | Baseline; After 12 week training or 6th month postpartum | We use Urostym to measure pelvic floor muscle strength which can identity the strength between Type I muscle fibers and Type II muscle fibers. |
| Change from Baseline pelvic floor muscle strength at 1 year postpartum | Baseline; 1 year postpartum | The participants were instructed to contract the pelvic floor muscle correctly and allowed for one practice. Three times of maximum contraction holding for five seconds with an interval resting of five seconds were performed, and the maximum value among three was recorded as the muscle strength of maximal voluntary contraction. The result was recorded using the modified Oxford Grading scale, ranging from 0 to 5, which 0 represents no discernible pelvic floor muscle contraction and 5 represents a strong pelvic floor muscle contracion. |
| Change from Baseline pelvic floor electrophysiology at 1 year postpartum | Baseline; 1 year postpartum | We use Urostym to measure pelvic floor muscle strength which can identity the strength between Type I muscle fibers and Type II muscle fibers. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from pelvic sagittal rotation degree | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | The quantitative measurement of pelvic sagittal rotation degree on X-ray was analyzed which includes the pelvic tilt angle , the sacral slope angle, the difference of sacral slope and pelvic tilt, the ratio of the pelvic tilt angle to the sacral slope angle, the ratio of the pelvic tilt angle to the pelvic incidence angle and sacral-femoral distance. |
| Change from body composition | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | Body composition analysis is measured which mainly includes Body Mass Index（BMI）based on height and weight in kg/m\^2. |
| Change from body strength | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | Hand grip strength and trunk endurance are measured to describe body strength. Hand grip strength was measured by JAMAR Plus+ grip gauge. The measurement accuracy is 0.1kg. The participants should not have visible hand defects. The grip gauge should be adjusted before measurement. When the paticipants holds the grip gauge, the second knuckle of the index finger should be at 90 degrees. At the same time, mark the best position of each hand on the grip meter. Before measurement, the participants should remove wrist jewelry to avoid injury. And the left and right hand are measured alternately for 3 times. |
| The occurrence of SUI | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | SUI is defined by SUI symptoms or a positive result of the stress test. Before the stress test, participants are suggested to keep fully bladder. Positive result of the stress test is defined as involuntarily urinary leakage when asked to cough in the lithotomy position. |
| Change from PFIQ-7 Questionnaire Score | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | The Pelvic Floor Impact Questionnaire-7 (PFIQ-7) is a shortened, less comprehensive version of the Pelvic Floor Impact Questionnaire (PFIQ).To get scale scores, the mean of each of the 3 scales is individually calculated, which ranges from 0-3, this number is then multiplied by 100 and then divided by 3.The scale scores are then added together to get the total PFIQ-7 score, which ranges from 0-300. A lower score means there is a lesser effect on quality of life. |
| Change from FSFI-6 Questionnaire Score | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | The 6-item Female Sexual Function Index (FSFI) is a short form of the original 19-item FSFI that measures sexual function in women.It comprises six domains: desire, arousal, lubrication, orgasm, satisfaction, and pain. Desire and satisfaction items are rated on a 5-point Likert scale, ranging from 1 to 5, and the other items are rated on a 6-point Likert scale, ranging from 0 to 5. Total scores range from 2 to 30, with lower scores indicating worse sexual functioning. |
| Change from the Pittsburgh Sleep Quality Index (PSQI) Score | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Nineteen individual items generate seven component scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these seven components yields one global score. The 18 items consist of 7 components, and each component is scored according to the grade of 0 \ 3. The cumulative score of each component is the total score of PSQI, and the total score range is 0\ 2l. The higher the score, the worse the sleep quality. It takes 5 to 10 minutes for the participants to complete the question. |
| Change from Pelvic Floor Distress Inventory（PFDI-20）Questionnaire Score | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | The Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20) is the short-form version of the Pelvic Floor Distress Inventory (PFDI).Since it is comprised of the UDI-6, POPDI-6, and the CRADI-8, the PFDI-20 includes 20 questions.The scale scores are found individually by calculating the mean value of their corresponding questions and then multiplying by 25 to obtain a value that ranges from 0 to 100.The sum of the 3 scales are added together to get the PFDI-20 summary score, which ranges from 0 to 300. |
| Change from Pelvic floor ultrasound indicators | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | LAM thickness, diameter of the levator hiatus and levator hiatus area |
| Change from Pelvic Organ Prolapse Quantitation | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | Pelvic Organ Prolapse Quantitation is measured by callipers |
| Change from Physical activity levels | Baseline; After 12 week training or 6th month postpartum；1 year follow-up | We use International Physical Activity Questionnaire score to measure the overall physical activity level during postpartum period. |
