Abstract
Background Urinary incontinence affects one in three women worldwide. Pelvic floor muscle training is an effective treatment. Electromyography biofeedback (providing visual or auditory feedback of internal muscle movement) is an adjunct that may improve outcomes. Objectives To determine the clinical effectiveness and cost-effectiveness of biofeedback-mediated intensive pelvic floor muscle training (biofeedback pelvic floor muscle training) compared with basic pelvic floor muscle training for treating female stress urinary incontinence or mixed urinary incontinence. Design A multicentre, parallel-group randomised controlled trial of the clinical effectiveness and cost-effectiveness of biofeedback pelvic floor muscle training compared with basic pelvic floor muscle training, with a mixed-methods process evaluation and a longitudinal qualitative case study. Group allocation was by web-based application, with minimisation by urinary incontinence type, centre, age and baseline urinary incontinence severity. Participants, therapy providers and researchers were not blinded to group allocation. Six-month pelvic floor muscle assessments were conducted by a blinded assessor. Setting This trial was set in UK community and outpatient care settings. Participants Women aged ≥ 18 years, with new stress urinary incontinence or mixed urinary incontinence. The following women were excluded: those with urgency urinary incontinence alone, those who had received formal instruction in pelvic floor muscle training in the previous year, those unable to contract their pelvic floor muscles, those pregnant or
