Over Active Bladder

This study is a single-site feasibility randomised controlled trial evaluating the feasibility and acceptability of electroacupuncture (EA), percutaneous tibial nerve stimulation (PTNS), and sham electroacupuncture in women with refractory overactive bladder (OAB) who have not achieved satisfactory improvement following standard pelvic health physiotherapy. The primary aim is to determine whether a larger definitive trial is feasible by assessing recruitment, consent, retention, treatment adherence, data completeness, intervention delivery, blinding credibility, safety, and participant acceptability. Thirty-six participants will be randomly allocated to receive electroacupuncture, PTNS, or sham electroacupuncture over a 12-week treatment period. Outcome assessments will be completed at baseline, 6 weeks, 12 weeks, 6 months, and 12 months. The findings will inform the design of a future definitive randomised controlled trial and contribute to the evidence base for non-pharmacological treatment options for overactive bladder.

The Confidanz Smart Patch System consists of a Smart Patch containing one transcutaneous gel electrode and one percutaneous microneedle array electrode that sits directly superficial to the posterior tibial nerve. An applicator is used by the patient to deploy the microneedles into the skin. A Capital Stimulation Unit (CSU) is magnetically aligned with the Smart Patch and generates biphasic current wave form to the posterior tibial nerve through the patch. The CSU is connected to a mobile application via Bluetooth, allowing control over the stimulation intensity parameters. Primary Objective: To investigate the safety of the Confidanz Smart Patch System for adults diagnosed with idiopathic overactive bladder. Secondary Objective: To measure the reduction from baseline in average incontinence events (IE) per day at 6- and 12-weeks. Primary Hypothesis: The use of the Confidanz Smart Patch System is safe for use in adults with idiopathic overactive bladder.
