- Modified ride-on cars are provided to children as a means of independent mobility. Purpose: The purpose of this study was to examine how the provision of modified ROCs to children with disabilities affects the development of problem-solving and personal-social skills. Methods: The amount of time children spent driving the modified ride-on cars during a 3-month period was recorded, as well as their pre and post-intervention Ages and Stages Questionnaire (ASQ) scores for the categories of problem-solving and personal-social skills. Results: The group was divided in half, with the children who used the car the most being placed in the High Utilization group and the children who used the car the least being placed in the Low Utilization group. The acquisition of skills was slightly higher in the Low Utilization group, but there was not a significant difference between the number of skills gained by either group. Conclusion: The lack of impact of the cars may be due to their extremely low levels of use. Specific guidelines for use, regular communication with the researchers, and the usage of a modified ride-on car in a clinical setting may improve the frequency of its use and its impact on the child.
