Influence of Combined Transcranial Direct Current Stimulation and Motor Training on Corticospinal Excitability in Children With Unilateral Cerebral Palsy
Conclusion
This proof-of-principle study evaluated the influence of cathodal contralesional tDCS on corticospinal excitability in pediatric participants with UCP. A hypothesized decrease in contralesional excitability was noted in participants in the Active+CIMT group, however, the efficacy of tDCS to modulate corticospinal excitability was not statistically different than the Sham+CIMT group. A more detailed understanding of how tDCS impacts M1 neurophysiology will be essential to inform future clinical trials on the optimal dosing parameters, based on individual brain circuitry, to explore the potential functional benefit of both neuromodulation and motor training.
