Bimanual Skill Learning after Transcranial Direct Current Stimulation in Children with Unilateral Cerebral Palsy: A Brief Report

Bimanual skills are important for goal-oriented activities. Children with unilateral cerebral palsy (UCP) have deficits in unimanual and bimanual motor control and learning. The application of non-invasive brain stimulation with existing motor training may further promote motor learning, however the effects of stimulation on bimanual learning have not been examined. Here, we assessed performance of a novel bimanual skill (modified Speed Stacks task) in eight children with UCP before, during, and after a combined motor training and brain stimulation intervention. Participants received ten days (120 minutes/day) of goal-oriented bimanual therapy combined initially with transcranial direct current stimulation (tDCS, 20 minutes/day). Results showed task improvement tapered (p
