Shock therapy for bladder troubles: new hope for MS patients?
NCT ID NCT04573673
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a non-invasive treatment called transcutaneous tibial neuro-stimulation (TTNS) to help people with multiple sclerosis who have trouble emptying their bladder. Participants will use a device at home for 30 minutes each day for 12 weeks. The goal is to see if this stimulation improves bladder function compared to a placebo device.
