The use of adapted motorized vehicles with controlled acceleration: Focus on child’s acceptance

Mobility is essential for the development of children with disabilities. The Adapt Project uses motorized adapted cars to promote independent movement and positively impact child development. To evaluate whether the perception of acceleration influences children's initial adaptation to the device. This case study involved an initial intervention and a three-month follow-up after delivering the adapted car. First, the child was evaluated using the car without and with acceleration control, assessed with the FLACC and ALP scales. Second, follow-up sessions were conducted with active maternal participation. Third, qualitative interviews were conducted, and the QUEST 2.0 scale was applied to assess satisfaction. Rapid acceleration movements increased pain perception, while slow movements minimized discomfort. The child progressed from level 1 to levels 3 and 4 on the ALP scale, and the QUEST 2.0 scale demonstrated high satisfaction (4.91), highlighting safety, comfort, and technical support, after 3 months of usage. Adaptations to the device and family engagement were essential for device acceptance and motor-cognitive development. Acceleration control improved comfort and safety, enabling greater autonomy and interaction, emphasizing the importance of user-centered approaches in assistive technologies.
