IMPORTANCE: Virtual reality (VR) intervention may offer significant benefits in improving motor, cognitive, and sensory-perceptual skills and activity levels among children with developmental coordination disorder (DCD), a condition often affecting daily functioning. OBJECTIVE: To examine the effect of VR intervention on motor, cognitive, and sensory-perceptual skills and activity levels among children with DCD from the International Classification of Functioning, Disability and Health perspective. DESIGN: Single-blind randomized controlled trial. SETTING: University hospital. PARTICIPANTS: 48 children, ages 5 to 8 yr. Intervention: The study group received VR in addition to COT, and the control group received only COT. In the COT-only program, sensorimotor-based activity approaches were used to provide children with diverse sensorimotor experiences. Both interventions took place 2x/week for 8 weeks, totaling 16 sessions. Outcomes and Measures: Participants were evaluated using the Test of Gross Motor Development (2nd ed.), Childhood Executive Functioning Inventory, Sensory Integration and Praxis Test, Motor-Free Visual Perception Test (3rd ed.), and Functional Independence Measure for Children. RESULTS: The study group showed statistically significant improvements in motor, cognitive, sensory-perceptual skills, and activity levels (p < 0.05). The control group showed significant improvements in only sensory-perceptual skills and activity levels (p < 0.05), with no significant differences in motor and cognitive skills (p > 0.05). The study group showed stronger effects across all measured areas (d > 0.8). CONCLUSIONS AND RELEVANCE: Adding VR to COT was more effective than COT alone in enhancing motor, cognitive, and sensory-perceptual skills and activity levels. These results highlight the potential of VR in pediatric rehabilitation to improve therapeutic outcomes.
