Can a nerve stimulation device outdo pelvic floor exercises for overactive bladder?
NCT ID NCT07788560
First seen Aug 26, 2026 · Last updated Aug 27, 2026 · Updated 1 time
Summary
This trial compares two non-invasive treatments for overactive bladder (OAB): transcutaneous peroneal electrical neuromodulation, which uses surface electrodes to stimulate a nerve in the leg, and pelvic floor exercises, a standard behavioral therapy. Adults with idiopathic OAB will be randomly assigned to one of the two treatments for three months. Researchers will measure changes in bladder symptoms using diaries and questionnaires to see if the nerve stimulation offers comparable or better relief than exercises.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Transcutaneous peroneal electrical neuromodulation (a device that delivers electrical stimulation to the peroneal nerve) and pelvic floor exercises (a behavioral therapy)
- What this could lead to
- If effective, this could offer a non-invasive, drug-free option to reduce overactive bladder symptoms, potentially improving quality of life for many adults.
- What could go wrong
- This is a small, early-stage trial, so results may not be conclusive or widely applicable. The treatment may not outperform standard exercises, and electrical stimulation could cause discomfort or skin irritation.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults aged 18 years or older. * Diagnosis of idiopathic overactive bladder (OAB) based on clinical evaluation. * Presence of urinary urgency, with or without urgency urinary incontinence, usually accompanied by increased urinary frequency and/or nocturia. * OAB symptoms present for at least 3 months. * Ability to complete bladder diaries and symptom questionnaires. * Willingness to participate in the study and provide written informed consent. * Ability to comply with the assigned treatment protocol and scheduled follow-up visits. Exclusion Criteria: * Neurogenic lower urinary tract dysfunction or a known neurological disease affecting bladder function. * Active urinary tract infection at the time of enrollment. * Significant pelvic organ prolapse. * Predominant stress urinary incontinence or mixed urinary incontinence with predominant stress symptoms. * Clinically significant bladder outlet obstruction or urinary retention. * History of major pelvic surgery or pelvic radiotherapy that may affect lower urinary tract function. * Previous treatment with botulinum toxin injection or neuromodulation within the predefined washout period. * Current use of OAB medications that cannot be discontinued or appropriately washed out before enrollment. * Pregnancy. * Presence of a cardiac pacemaker, implanted defibrillator, or another implanted electrical device incompatible with electrical stimulation. * Any condition that, in the investigator's judgment, would prevent safe participation or adherence to the study protocol.
