Study Summary
Overactive bladder (OAB) is a chronic disorder with an overall prevalence in the adult population of over 10%, but that may exceed 40% in elderly groups. Most overactive bladder treatments are aimed at decreasing urgency incontinence episodes. The purpose of this study is to determine whether an at-home transvaginal electrical stimulation (TES) program works to alleviate symptoms of urgency in patients with urinary urgency and frequency without incontinence. This is a cross-over trial. Women \>18 yo presenting with OAB-dry will be randomized to receive one of two TES at home programs for 4 weeks. After completion of the program, the participant's symptoms will be assessed with standardized patient questionnaires. There will then be a 3 week washout period followed by the second at-home TES program. At the completion of the second program, the participant's symptoms will be assessed with the same standardized questionnaires. The participants will be followed for 6 months following the completion of the TES program.
Primary Outcome
The primary outcome is the change in participant's reported urgency as measured by the composite score of the first 8 questions of the OAB-q questionnaire. The questionnaire is out of 8 with higher scores corresponding with more bother from urinary urgency. The primary outcome is the difference between the pre-treament and post-treatment scores. The range is 0 to 48 with a larger difference corresponding to more improvement in patient's urgency over the study period.
