Tactile Feedback Pelvic Floor Training to Prevent Stress Urinary Incontinence in the 3rd Trimester of Pregnancy

17 augusti 2026 uppdaterad av: Ya-Wel Chu, Far Eastern Memorial Hospital

Tactile Feedback on Pelvic Floor Muscle Training in the 3rd Trimester of Pregnancy to Prevent of Stress Urinary Incontinence and Its Influence on Biological and Psychological Symptoms

Pregnancy involves significant physiological changes, such as hormone fluctuations, weight gain, and fetal growth, which can affect multiple organ systems. These changes often lead to symptoms like stress urinary incontinence (SUI) and may worsen existing conditions. SUI affects about one-third of pregnant women and can decrease quality of life.

Pelvic floor muscle exercise (PFME) is a recommended treatment to manage urinary incontinence during pregnancy and postpartum. This study aims to compare the effectiveness of three interventions: routine health education, traditional PFME, and tactile feedback PFME, on reducing SUI symptoms, shortening the second stage of labor, and improving quality of life.

Participants will be enrolled in their third trimester and randomly assigned to one of the three groups, with each intervention lasting 8 weeks. Outcome measures include urinary symptoms (via bladder diary, UDI-6, and IIQ-7), quality of life (via KHQ and WHOQOL-BREF), and labor outcomes (duration of the second stage).

Detaljerad beskrivning

This study compares the effectiveness of three interventions-routine health education, traditional pelvic floor muscle exercise (PFME), and tactile feedback PFME-in improving urinary incontinence in pregnant women. Participants will receive one of these interventions over 8 weeks during the third trimester. The primary outcome measures include changes in urinary incontinence symptoms, quality of life,and the duration of the second stage of labor. Participants will be evaluated at baseline and 8 weeks post-intervention. This study also aims to determine whether tactile feedback PFME is more effective than traditional PFME or routine health education in reducing urinary incontinence symptoms and improving labor outcomes.

Deltagargrupp / Arm
Intervention / Behandling
Placebo-jämförare: Basic Health Education Group
Participants in this group receive a one-time, written health education leaflet, without any physical or in-person instruction. The leaflet includes information on the occurrence and causes of urinary incontinence during pregnancy, dietary recommendations, weight management, and illustrated instructions for Kegel exercises.
Beteende: Basic Health Education Group
One-way, one-time health education leaflets are provided for written teaching, with only explanations but no physical teaching. The content of the health education leaflets includes urinary incontinence during pregnancy, its causes, daily diet, weight control, and Kegel exercise execution methods and movements.
Aktiv komparator: Kegel Exercise Group
Participants in this group receive four in-person sessions of conventional pelvic floor muscle training (PFMT) over an 8-week period. The training is delivered through interactive, hands-on teaching methods, incorporating posture positioning, guided breathing techniques, and imagery-based instructions (e.g., "closing the door," squeezing the buttocks) to enhance awareness and execution of Kegel contractions.
Beteende: Pelvic floor muscle training
"Four in-person traditional pelvic floor muscle training sessions are scheduled over an eight-week period. The training involves interactive, hands-on teaching that incorporates body positioning, guided breathing, and the 'closing and opening gate' theory. This includes imagery techniques such as buttock squeezing and simulating the action of stopping urine flow to facilitate pelvic floor muscle contractions.
Experimentell: Sensorimotor-Enhanced PFMT
This group receives sensorimotor-enhanced pelvic floor muscle training (PFMT) in four in-person sessions over an 8-week period. The training incorporates interactive instruction with body positioning, guided deep breathing, and finger-based tactile feedback. Participants are guided to sense the lift and contraction of their pelvic floor muscles through palpation techniques, aiming to enhance muscle awareness and neuromuscular coordination.
Beteende: Tactile pelvic floor muscle training group
There are four physical tactile pelvic floor muscle training courses arranged in eight weeks. The training process adopts two-way interactive practical teaching, using movement positioning and deep breathing to induce adjustment of the upper and lower strength of the pelvic floor, and using finger tactile feedback to feel the muscles lifting and contracting up and down during training.
