HABIT is a child-friendly, intensive intervention directed at improving bimanual coordination and function of the affected arm. The intervention employed in this study includes various age-appropriate fine and gross motor bimanual activities that will be delivered in a play context. Children practice bimanual activities for 6 hours per day, 5 days per week, for 1 week.

Children practices bimanual cup stacking, 15 trials/day for 5 consecutive day.

All children undergo training on a balance board, learning to hold the board level with equal weight on each leg and using various bilateral upper extremity strategies. Participants perform the balance task for 15, 30-second trials per day at visits 2-6.
