Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Women only
  • No healthy volunteers
  • Adult, Older adult

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.

Who may be able to join

  • 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).

Who cannot join

  • 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.

About this study

Official title: Establishment of an Artificial Intelligence Multidimensional Early Warning Diagnostic and Prognostic Model of Pelvic Floor Rehabilitation Therapy in the Chinese Population: a Prospective Cohort Study.

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. 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. 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. Which pelvic floor rehabilitation therapy is most suitable for Chinese patients with female pelvic floor dysfunction?
  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.
Read the detailed description

This multicentre, prospective cohort study will be conducted at seven hospital-based pelvic floor health centres nationwide in China. Patients with pelvic floor dysfunctional disorders who are scheduled to undergo pelvic floor rehabilitation are included, including 1) postpartum pelvic floor muscle weakness, 2) mild-to-moderate pelvic organ prolapse (POP), and 3) POP in combination with dysfunction (bowel or bladder dysfunction) or POP in combination with lower urinary tract symptoms (overactive bladder syndrome, constipation, faecal incontinence).

Pelvic floor rehabilitation was performed in accordance with the clinical pathway based on patients' disease characteristics and individual conditions, during which baseline data were collected from patients who met the inclusion and exclusion criteria, as well as follow-up surveys at the end of the treatment, 3 months after the end of the treatment, and 12 months after the end of the treatment. The clinical data collected were used to determine the effectiveness of treatment and to summarise the effects of different rehabilitation programmes on the prognosis of postpartum and middle-aged and elderly PFD patients. The data were matched and compared with the patients' clinical symptoms, signs and auxiliary examinations, so as to optimise and determine the individualised and precise pelvic floor rehabilitation treatment plan.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pelvic floor muscle trainingBehavioural

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

  • Biofeedback electrical stimulationOther

    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.

  • Magnetic StimulationOther

    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.

  • Magnetic stimulation combined with biofeedback electrical stimulationOther

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

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

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

  2. 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.

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

Secondary outcomes (2)
  1. POP-Q

    The patient empties the bladder in a quiet state and is examined in the truncated position, the maximum degree of prolapse that can be achieved with a forceful downward breath-hold in the Valsalva manoeuvre.

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

  2. PFDI-20

    Clinical symptoms are collected using the validated Chinese version of the international standardised questionnaire: PFDI-20, and patients are asked to select the answers that apply to their situation.

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