Pelvic Floor Rehabilitation of Female Pelvic Floor Dysfunction

Официальное название

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.

Обзор

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.

Подробное описание

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.

Вмешательства

• Поведенческое Pelvic floor muscle training
  A therapist will instruct the patient to contract the anus, perineum as well as the urethra, until the patient masters the correct method.
• Другое Biofeedback electrical stimulation
  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.
• Другое Magnetic 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.
• Другое Magnetic stimulation combined with biofeedback electrical stimulation
  Pelvic floor magnetic stimulation for 30 minutes followed by biofeedback electrical stimulation.
