Brain zaps + hand training: new hope for stiff muscles in kids with CP?
NCT ID NCT06128746
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a non-invasive brain stimulation technique called rTMS, followed by intensive arm training, can reduce muscle stiffness (spasticity) in children aged 7–18 with hemiplegic cerebral palsy. Twenty participants will receive either real or sham rTMS over 10 days. Researchers will measure changes in muscle tone, hand function, and brain activity using MRI scans.
