Inspiration From Eye-tracking Data: Investigating the Impact of Combining Specific Environmental Features and Power Mobility Training

This study has three main objectives. First, the investigators want to see how using a lightweight head-mounted eye tracker (HMET) can help to understand looking behavior, visual focus, and social interaction in toddlers with motor delays during ROC-Stand training. The investigators will compare the effects of training with specific environmental features to training without these features and to conventional therapy. Second, the investigators will evaluate outcomes related to body function, daily activities, and participation, along with family perceptions and involvement, using the ICF framework. Third, the investigators will explore how temperament, motivation, looking behavior, and caregiver-child interactions relate to each other in these toddlers across different training programs. Based on previous research, the investigators plan to recruit 30 toddlers with motor delays and randomly assign them to one of three groups: ROC-Stand with specific environmental features (ROC-Stand(SE)), ROC-Stand without these features (ROC-Stand(NSE)), and conventional therapy (Control), with 10 toddlers in each group. Each toddler will receive a total of 48 hours of training over 24 weeks, with two 120-minute sessions per week-12 weeks of intervention followed by a 12-week follow-up. The participants will also continue their regular therapy during the study. The HMET will record visual and manual behaviors for 20 minutes each week, and standardized assessments of body function, mobility, psychosocial function, family perception, and participation will be done before the intervention, after the intervention, and at the end of the follow-up. The findings from this study will help identify key environmental factors for early power mobility training and provide families and therapists with a clear, structured approach to using these techniques.
