Intervention type: BEHAVIORAL
Group type: ACTIVE_COMPARATOR
Intervention: Ride-On Cars Training with Different Postures
Description: A licensed, independent therapist and caregivers will provide the training program in the public space in the university for a total of 12-week intervention based on ecological and dynamic systems theories. Training will concentrate on building the concept of casual-effect on the control system and car motion, practicing goal-oriented driving (e.g., driving 200 meters and reach for a toy or contact with a person, play hide-and-seek) in certain public spaces, including hallways, convenient stores, garden, museum and upper limb use in functional tasks with driving, facilitating hand use in functional tasks for exploration and applying various motor skills for mobility and socialization in natural play session.
