This study found that infants with Down syndrome can feasibly use a modified ride-on car in both seated and standing positions. Further research is needed to improve adherence to this potentially beneficial intervention.
Area of Science:
- Pediatric Rehabilitation
- Developmental Pediatrics
- Assistive Technology
Background:
- Infants with Down syndrome often experience motor delays.
- Early motor interventions can improve developmental outcomes.
- Ride-on cars offer a novel approach to promoting early mobility.
Purpose of the Study:
- To assess the feasibility of a modified ride-on car for infants with Down syndrome.
- To evaluate infant engagement and independent use of the device.
- To identify potential barriers to intervention adherence.
Main Methods:
- A 9-month intervention study involving 4 infants with Down syndrome.
- Families were instructed to provide daily use of a modified ride-on car.
- Data collection focused on adherence rates and infant interaction with the device.
Main Results:
- Infants successfully activated the modified ride-on car in seated and standing modes.
- Participants demonstrated enjoyment and independent use of the device.
- Adherence rates varied among families, indicating a need for further investigation.
Conclusions:
- The modified ride-on car intervention is feasible for infants with Down syndrome.
- The device promotes independent mobility and engagement.
- Addressing adherence barriers is crucial for future research and clinical application.
