A213: Somatosensory Interactive Technology on Postural Balance in Children with Developmental Coordination Disorder

Developmental coordination disorder (DCD) is a neurodevelopmental disorder characterized by motor coordination impairments and motor learning difficulties. Compared with typically developing children, children with DCD often exhibit deficits in postural control, strength, and cardiorespiratory fitness. This study used a systematic review method to review the relevant evidence of video-game interventions in children with DCD, aiming to explore the mechanisms of somatosensory interaction technology on balance ability of children with DCD, and provide evidence-based recommendations for parents, teachers, and rehabilitation therapists. A PICO framework was constructed to systematically search Chinese and English literature on the intervention of video games on balance in children with DCD from CNKI, PubMed, Web of Science, EBSCO, Embase, and Cochrane Library. The search time was from the establishment of the database to November 14, 2024. The Physiotherapy Evidence Database (PEDro) scale was used to assess study quality, followed by data extraction and synthesis for the systematic review. Finally, 15 articles were included, with a total of 654 DCD and typically developing children, aged 5-16 years. The PEDro scale scores ranged from 3 to 8 points. Studies were from the Netherlands, Israel, South Africa, Brazil, Australia, and the United Kingdom, randomized controlled trials, 4 controlled trials, 1 quasi-experimental, and 1 single-group trial. The intervention used video games based on somatosensory interaction technology, mainly using Wii Fit, Xbox Kinect, and EyeToy devices, and the intervention contents included sports games such as archery, jumping, bowling, table tennis, football, Frisbee, skiing, and dancing. The intervention frequency was 15 times per week, 1060 minutes per session, for 14 weeks, and was conducted in school, home, and laboratory settings. The results show that video games based on somatosensory interaction technology have the characteristics of real-time interaction and timely reinforcement feedback, improve the physical function and activity participation of children with DCD, and have a significant effect on the improvement of postural balance. However, this study has limitations, including significant heterogeneity in experimental designs, sample characteristics, and intervention protocols across the included studies, as well as the omission of relevant outcome indicators such as psychological outcomes. Future research should prioritize high-quality randomized controlled trials to evaluate the effectiveness of video-game interventions on both physical and psychological health outcomes in children with DCD.
