Comparative Effectiveness of Pelvic Floor Muscle Training, Mirabegron, and Trospium Among Older Women With Urgency Urinary Incontinence and High Fall Risk: a Feasibility Randomized Clinical Study

The University of Texas Medical Branch, Galveston·interventional·Posted May 30, 2023·Updated Jun 22, 2026

In Brief

A Early Phase 1 clinical trial evaluating Pelvic Floor Muscle Training, Mirabegron, and 1 other intervention for Urinary Bladder, Overactive and 2 related conditions. Completed, enrolled 48 participants across 1 site.

Detailed Summary

The goal of this study is to conduct a randomized pilot multi-arm clinical trial comparing a standard course of physical therapist provided pelvic floor muscle training (PFMT) to pharmacologic therapy for the treatment of urgency urinary incontinence (UUI) or Overactive Bladder (OAB) in older women at high risk of falling. The central hypotheses for this project are i) a randomized pilot multi-arm clinical trial comparing PFMT to drug treatment for UUI or OAB in older women at high risk of falling is feasible; and ii) treatment approach can influence both UI and fall related outcomes in this patient population. The main questions it aims to answer are: 1) Is a multi-arm clinical trial comparing PFMT to drug treatment for UUI or OAB in older women at high risk of falling feasible? and 2) How does treatment approach influence both OAB and fall related outcomes in this patient population? Women (16 per arm) 60 years and older with UUI or OAB who screen positive for high fall risk will be randomized to one of three standard of care treatment arms and followed for six months. The three treatment arms are i) a 12-week structured behaviorally based pelvic floor muscle training (PFMT) intervention administered by physical therapists in the outpatient physical therapy clinic; ii) a 12-week course of the beta-3 agonist, Mirabegron; and iii) a 12-week course of the antimuscarinic, Trospium Chloride. Researchers will compare study feasibility and OAB symptom related outcomes across the three groups to see if a larger clinical trial is warranted.
