Bladder Training With or Without Biofeedback-Assisted Pelvic Floor Muscle Training for Women With Wet Overactive Bladder
Sponsor: Gaziantep Islam Science and Technology University
Summary
Overactive bladder causes a sudden and difficult-to-control need to urinate and may be accompanied by urine leakage. Bladder training is commonly used as a first-line treatment. Pelvic floor muscle training supported by electromyographic biofeedback may help women recognize and contract the correct muscles and improve control of urgency and leakage. The purpose of this randomized controlled trial was to determine whether adding electromyographic biofeedback-assisted pelvic floor muscle training to bladder training provides additional benefit compared with bladder training alone in women with wet overactive bladder and urodynamically confirmed detrusor overactivity. A total of 64 women were randomly assigned in a 1:1 ratio to receive either bladder training alone or bladder training plus electromyographic biofeedback-assisted pelvic floor muscle training. Both interventions lasted 8 weeks. Participants in the combined intervention group received 24 supervised biofeedback sessions in addition to bladder training. The primary outcome was the change in daily voiding frequency measured using a 3-day bladder diary. Secondary outcomes included urgency, urgency urinary incontinence, nocturia, incontinence-related quality of life, pelvic floor muscle function, treatment adherence, treatment satisfaction, and adverse events. Outcomes were assessed at baseline and at week 8.

Interventions
Bladder Training
An 8-week bladder training program including education on lower urinary tract anatomy and overactive bladder, counseling regarding fluid intake and bladder irritants, timed voiding, progressive extension of voiding intervals, and urgency-suppression strategies. Voiding intervals were individualized according to the baseline bladder diary and gradually increased according to participant tolerance.
EMG Biofeedback-Assisted Pelvic Floor Muscle Training
An 8-week individually supervised pelvic floor muscle training program using surface electromyographic biofeedback. Participants received three sessions per week for a total of 24 sessions. Surface perineal electrodes provided visual feedback during isolated pelvic floor muscle contractions. Each session included 40 slow contractions consisting of 10 seconds of contraction and 20 seconds of relaxation, followed by five sets of 10 fast contractions consisting of 1 second of contraction and 2 seconds of relaxation, with 2-minute rest periods between sets.
