Ankle zaps may curb bladder leaks in kids with spina bifida
NCT ID NCT06025734
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a treatment called transcutaneous tibial nerve stimulation (TTNS) for children aged 8-18 with spina bifida who still leak urine despite regular catheter use. TTNS uses mild electrical pulses at the ankle to stimulate a nerve that helps control the bladder. Participants will receive 6 weekly treatments (done at home after the first session) and track leakage episodes, pad use, and quality of life. If it works, treatment may continue for another 6 weeks.
