Can nerve stimulation beat education for overactive bladder?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Stable on chronic medications: Participants must have been on a long-term, regular regimen of routine medications for chronic conditions (e.g., hypertension, diabetes, hyperlipidemia) prior to study entry, with no expected changes in dosage or administration during the 8-week study period. * Diagnosed with Overactive Bladder (OAB) according to the International Continence Society (ICS) definition, including urgency, frequency, and nocturia, with or without urgency urinary incontinence (must be documented as OAB-wet or OAB-dry). * Symptoms persisting for at least 3 months. * Overactive Bladder Symptom Score (OABSS) total score ≥ 3 at baseline (Week 0), with an urgency score (Question 3) ≥ 2 (meeting the clinical threshold for core OAB symptom intensity). Exclusion Criteria: * Concurrent active urinary tract infection (UTI), bladder stones, or urinary tract malignancy. * Inability to follow instructions for muscle training due to cognitive impairment or severe psychiatric illness. * Presence of implanted electronic medical devices (e.g., cardiac pacemakers) (contraindication for electrical stimulation). * Currently pregnant women or those planning to become pregnant during the study period. * Use of antimuscarinics (e.g., Oxybutynin, Tolterodine, Solifenacin) or beta-3 adrenergic receptor agonists (e.g., Mirabegron) within 2 weeks prior to study entry. * Receipt of pelvic or perineal physical therapy outside of this study protocol (e.g., vaginal or anal probe electrical stimulation, pelvic floor magnetic stimulation, transcutaneous microcurrent stimulation) within 2 weeks prior to study entry. * Receipt of intravesical Botulinum toxin (Botox) injections, sacral neuromodulation, or any surgical treatment related to urinary incontinence or pelvic organ prolapse within 2 weeks prior to study entry.
