Following on our successful results of bimanual training (HABIT) in children with congenital hemiplegia (CP), we received some seed money from the Brain Recovery Project to study bimanual training in children who have undergone a hemispherectomy. The study involved undergoing clinical testing and an MRI before and after treatment (unsedated) and participating in our fun 3 week day camp held here at our research center. This study is no longer recruiting.
