From 14 children with acquired or congenital brain injury and 10 sex- and age-matched healthy controls, we acquired resting state (RS) functional MRI data before constraint-induced movement therapy (CIMT) (baseline), at the end of CIMT (week 10) and after 6 months. Functional network connectivity was used to assess significant interactions among resting state networks at baseline, and changes of association between networks at the two follow-up evaluations. Changes of resting state connectivity among sensory, motor and cognitive networks were detected in pediatric patients with chronic hemiplegia after CIMT. Such changes correlated with clinical improvement following treatment.
