PMID 41316406WHAT IT FOUND
Adding brain stimulation to therapy did not improve upper limb movement in children with cerebral palsy or stroke.
The combined treatment showed no benefit over standard care alone, so clinicians should not expect these stimulation techniques to enhance motor recovery on their own.
Key findings
01Neither repetitive transcranial magnetic stimulation (rTMS) nor transcranial direct current stimulation (tDCS) produced a statistically significant improvement in upper limb motor activity compared to sham or control conditions.
02The review found moderate certainty evidence that non-invasive brain stimulation does not demonstrate additional clinical effects on upper limb activity in children, requiring further high-quality research.
03While individual studies showed mixed results, the overall pooled analysis indicated no significant effect for either stimulation technique when applied in isolation or as an adjunct to usual rehabilitation.

What it does not show
The sample size for the meta-analysis was small, and the studies included had varying methodological quality. There was significant heterogeneity in tDCS protocols, including differences in electrode placement, intensity, and session numbers, making comparisons difficult. Subgroup analyses by severity of impairment (MACS levels) were not possible due to insufficient data stratification. The age range extended to 30 years, which may dilute the strict pediatric focus of the review.
Declared interests
The study was funded by Neuron Clinic.
The easy way to misread this
Do not interpret the null overall result as proof that brain stimulation never works for any child. The authors note a trend where recent studies using multiple sessions and combined intensive training showed some positive shifts, but the current pooled evidence remains insufficient to recommend these protocols.
