Introduction: Overactive bladder (OAB) is a common condition characterized by urinary urgency, frequency, and, in some cases, urge incontinence. Non-invasive neuromodulation has emerged as an effective therapeutic option by modulating the neural pathways involved in bladder control. This approach offers a promising alternative for patients who do not respond to conventional treatments.

Objectives: To evaluate the effect of non-invasive NESA neuromodulation compared to posterior tibial stimulation in patients with overactive bladder. compared to posterior tibial stimulation, with same-day exercises and patient education on quality of life, symptoms, discomfort and sleep. day of the session and patient education on quality of life, symptoms, discomfort and sleep.

Methods: Twenty-four patients (24 women), aged 38-85 years with overactive bladder will be included in this experimental clinical trial study. Each patient will attend ten sessions two days a week. Patient life quality will be measured using SF-36, sleep quality with the Pittsburgh questionnaire, perception of urinari incontinence (UI) symptoms and patient quality of life with the ICIQ-SF questionnaire. All these variables will be measured before, immediately after the ten sessions and at two months after the end of treatment. Ethic: The study was approved by the ethics committee of the University of Valencia, and all participants will be given an informed consent form.
