Treatment Efficacy for Overactive Bladder: Comparing Education, Biofeedback, and Nerve Stimulation

The purpose of this clinical trial is to evaluate the effectiveness of different behavioral therapies and neuromodulation for treating women with idiopathic Overactive Bladder (OAB). The study aims to compare three 8-week treatment plans: oral education on Pelvic Floor Muscle Training (PFMT), biofeedback-assisted PFMT, and biofeedback-assisted PFMT combined with tibial nerve electrical stimulation using the "Enraf-Nonius" EMG-Biofeedback Unit. The main question it aims to answer is whether adding biofeedback and peripheral nerve stimulation provides better relief for OAB symptoms (such as urinary urgency, frequency, and nocturia) compared to standard oral education on PFMT alone. Participants will be randomly assigned to one of the three treatment groups and will track their daily pelvic floor exercises at home using a smartphone timer application. The study will also analyze whether patients with different OAB phenotypes (OAB-wet versus OAB-dry) respond differently to these treatment interventions.
