Development of Modified Ride-On-Cars for Children with Mobility Impairments

Introduction: The ability to move independently is an integral part of a child's development. Children with motor impairments often experience significant challenges with moving independently, resulting in expensive powered wheelchairs being purchased or having caregivers push them in strollers or wheelchairs. The purpose of this research is to adapt motorized ride-on-cars to enable children with motor impairments to explore their environment independently. Engineers, physiotherapists, and occupational therapists co-designed customized ride-on-cars with 10 children and their caregivers to support each child’s individual needs. Methods: Physiotherapists and occupational therapists led an initial diagnostic session to assess each child’s clinical needs. The engineers then brainstormed and implemented solutions. On the final day of testing, physiotherapists and occupational therapists conducted one further clinical assessment and made final changes. This process was repeated for 10 children ages 1-3 years old who had been identified as having mobility impairment. Results: The final cars were designed to minimize cost, weight, and size while prioritizing each child’s ability to operate the car independently and safely. The main modifications included replacing the original gas pedal with an assistive switch and constructing a support frame to ensure the child’s safety. Additional modifications such as adding a steering T-bar, adding LED lights, and varying the switch location were also implemented for specific children. Each modified car was tested to ensure client safety and car durability. Client feedback was positive, and caregivers expressed how their modified car will increase mobility for their child. Conclusions: The results from this iterative co-design process emphasize the importance of team assessment and implementation when creating assistive devices. It shows that modifying standard off-the-shelf toys to the specific needs of children with disabilities can be successful and improve their quality of life.
