Young children have the highest incidence of Traumatic Brain Injury (TBI), often leaving lasting motor and cognitive deficits. My goal was to address upper limb motor deficits in a versatile, motivating, and affordable manner. There are currently few therapeutic toys available for children with severe impairments for training critical tasks such as reaching and grasping, and maintaining motivation is a constant challenge. Highly motivating motorized cars for kids (ride-on cars) have given children with neuromotor impairments the opportunity to gain independent mobility and have been associated with improvements in social development and engagement. I transformed a ride-on car into an engaging therapeutic tool for training reaching and grasping by modifying push, pull, and twist switches with a set of custom designed handles and knobs. I created an easily adjustable mounting arm to position the switches in an accessible manner. The design was evaluated on two five-year-old children with neuromotor impairments. Both children demonstrated increased usage of the switches. The interchangeable handles and adjustable mounting arm made the switch interface design a feasible way to provide upper limb therapy.
