Zapping the brain to calm an overactive bladder?
NCT ID NCT07768137
First seen Aug 17, 2026 · Last updated Aug 17, 2026
Summary
This trial tests whether a gentle brain stimulation technique called transcranial direct current stimulation (tDCS) can improve bladder control in people who have had a stroke. Participants will receive either real or sham tDCS alongside standard pelvic floor muscle training, three times a week for eight weeks. The goal is to see if this combination is feasible and helps reduce overactive bladder symptoms, which are common and distressing after a stroke.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Transcranial direct current stimulation (tDCS), a non-invasive brain stimulation device, combined with pelvic floor muscle training
- What this could lead to
- If it works, this could offer a drug-free way to ease bladder control problems after a stroke, improving quality of life without medication side effects.
- What could go wrong
- This is a small pilot study, so results may not be definitive. The stimulation is experimental, and its benefits for bladder symptoms are not yet proven.
