Study Overview
Brief Summary
The purpose of this study is to demonstrate superiority of percutaneous posterior tibial nerve stimulation (PTNS) therapy compared to sham therapy for the treatment of patients with overall bladder (OAB) symptoms.

Outcomes
Primary Outcomes
The Global Response Assessment (GRA) for Overall Bladder Symptoms to Compare the Proportion of Subjects Reporting "Moderately" or "Markedly Improved" Responses on the GRA After 12 Interventions of Randomized Therapy, in an Intent to Treat Analysis.
Time Frame: 13 weeks
A responder was defined as reporting bladder symptoms as moderately or markedly improved on a 7-level GRA at week 13 after completing 12, 30-minute, consecutive weekly intervention sessions.
Secondary Outcomes
