Electroacupuncture as a Treatment for Refractory Overactive Bladder
Sponsor: Chelsea and Westminster NHS Foundation Trust
Summary
Brief Summary The goal of this clinical trial is to learn whether electroacupuncture (EA) is as effective and acceptable as percutaneous tibial nerve stimulation (PTNS) in treating overactive bladder (OAB) in adult women. The main questions it aims to answer are: Does electroacupuncture reduce OAB symptoms to a similar extent as PTNS? Is electroacupuncture an acceptable and accessible treatment option for women with OAB? Researchers will compare EA and PTNS with a third group receiving sham acupuncture to see whether EA offers similar or better symptom relief and is more acceptable to participants. Participants will: Be randomly assigned to one of three groups: EA, PTNS, or sham acupuncture Receive one treatment session per week for 12 weeks Complete symptom diaries, quality-of-life questionnaires, and feedback on treatment acceptability Attend follow-up assessments after treatment ends The study will take place at Chelsea and Westminster NHS Foundation Trust, with support from the hospital's Physiotherapy and Urology departments. It is funded by the Chelsea and Westminster Hospital Joint Research Committee (JRC) and Supported by Imperial Collage London.
