Brief Summary

The goal of this observational study is to learn about the therapeutic effects of different pelvic floor rehabilitation treatments, including pelvic floor muscle training , pelvic floor biofeedback electrical stimulation, and magnetic stimulation, in a population of Chinese patients with female pelvic floor dysfunction disorders. The study aims to find out the individualised pelvic floor rehabilitation treatment plan suitable for the Chinese population. The main question it aims to answer is:

  1. 1.Do patients with reduced pelvic floor muscle strength after childbirth, or patients with mild to moderate pelvic organ prolapse and symptomatic pelvic organ prolapse benefit from pelvic floor rehabilitation?
  2. 2.Is the combination of biofeedback electrical stimulation plus pelvic floor magnetic stimulation superior to single electrical stimulation, magnetic stimulation or pelvic floor muscle training?
  3. 3.Which pelvic floor rehabilitation therapy is most suitable for Chinese patients with female pelvic floor dysfunction?
  4. 4.What factors are early predictors of developing female pelvic floor dysfunction? And what factors can predict the prognostic status of patients treated with pelvic floor rehabilitation? Participants in the multicenter will be treated with different rehabilitation therapies, during which the researchers will collect clinical symptoms using the PFDI20 questionnaire, and POP-Q scores, pelvic floor muscle strength, and electromyography results from participants before, at the end of, and 3 months and 1 year after the end of treatment.

Outcome Measures

Primary Outcomes (2)

  • pelvic floor muscle strength

    Pelvic floor muscle strength was assessed with reference to the Modified Oxford Muscle Strength Classification Method. Pelvic floor muscle strength was graded on a scale of 0-5: 0 for no contraction; 1 for tremor; 2 for slight contraction, with increased muscle strength but no lifting sensation; 3 for moderate contraction, with a sense of lifting of the posterior vaginal wall; 4 for good contraction, with a sense of lifting of the posterior vaginal wall against resistance; and 5 for strong contraction, with a sense of strong wrapping. The higher the grade, the better the pelvic floor strength.

    Baseline, 0 month and 3 months after pelvic floor rehabilitation treatment

  • pelvic floor electromyography

    Pelvic floor electromyography is assessed by the pelvic floor surface electromyography analysis and biofeedback training system. EMG values and parameters regarding muscle contraction and relaxation will be recorded.

    Baseline, 0 month and 3 months after pelvic floor rehabilitation.

Secondary Outcomes (2)

  • POP-Q

    Baseline, 0 month and 3 months after pelvic floor rehabilitation.

  • PFDI-20

    Baseline, , 0 month, 3 months and 1 year after pelvic floor rehabilitation.

Control group

Behavioral: Pelvic floor muscle training

pelvic floor biofeedback electrical stimulation

Observation Group 1

Other: Biofeedback electrical stimulation

pelvic floor magnetic stimulation

Observation Group 2

Other: Magnetic Stimulation

Magnetic stimulation combined with biofeedback electrical stimulation

Observation Group 3

Other: Magnetic stimulation combined with biofeedback electrical stimulation

Interventions

A therapist will instruct the patient to contract the anus, perineum as well as the urethra, until the patient masters the correct method.

pelvic floor muscle training (PFMT)

The therapist will place the electrodes of the instrument into the vagina, adjust the current value until the woman feels obvious contraction of the pelvic floor muscles but no pain, and instructs the patient to refer to the biofeedback mode for vaginal and anal contraction and relaxation.

pelvic floor biofeedback electrical stimulation

The therapist will use the magnetic stimulator to intermittently stimulate the and adjust the stimulation intensity at any time according to the patient\'s condition, adjusting it until there is a clear sense of contraction and feel comfortable.

pelvic floor magnetic stimulation

Pelvic floor magnetic stimulation for 30 minutes followed by biofeedback electrical stimulation.

Magnetic stimulation combined with biofeedback electrical stimulation

Sampling MethodProbability Sample
Study Population

This study is aimed at female patients with pelvic floor dysfunction. A large group of people are women who develop reduced pelvic floor muscle strength after childbirth; these women may not present with organic changes in the pelvic organs, but may present with symptoms such as unsatisfactory sexual behaviour and stress urinary incontinence as a result of weakened muscle strength. The other part of the population is patients with mild to moderate pelvic organ prolapse, where physical examination may reveal mild to moderate prolapse of the anterior vaginal wall, uterus, or posterior vaginal wall. If this group of patients had a combination of urinary and gastrointestinal symptoms, they could also be included in the study.

You may qualify if:

  • knowledge of the study, voluntary enrolment in the study, and signing of informed consent;
  • postpartum pelvic floor weakness (pelvic floor muscle strength less than grade 3), or mild to moderate pelvic organ prolapse (POP-Q staging less than stage III), or pelvic organ prolapse combined with dysfunction (bowel or bladder dysfunction).

You may not qualify if:

  • history of comorbid serious medical or surgical illness;
  • comorbid psychiatric disorders;
  • contraindications to electrical and magnetic stimulation such as implanted pacemakers;
  • pelvic malignancy, acute genitourinary infection or vaginal bleeding, and genital tract malformation.
