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.
