Enhancing social and linguistic skills in children with autism: A semi-randomized controlled clinical trial of a virtual reality-based communicative rehabilitation programme.

Autism spectrum disorder (ASD) is characterized by persistent deficits in social communication, and conventional therapies often struggle to facilitate the generalization of these skills to real-world settings. This study aimed to determine the effectiveness of a virtual reality (VR)-based communication rehabilitation intervention as a supplement to conventional treatment for improving the linguistic and social communication skills of Arabic-speaking Egyptian children with ASD. A clinical trial with a pretest-posttest control group design was employed, wherein 60 children aged 4-6 years with mild to moderate ASD were assigned to either VR plus conventional therapy (Group I, n = 30) or conventional therapy alone (Group II, n = 30). Over 6 months, participants received 2 weekly 30-min sessions. Outcomes were measured at baseline, immediately post-intervention and at a 3-month follow-up using the Preschool Language Scale-Fourth Edition, the Childhood Autism Rating Scale-Second Edition and an ASD Social Skills Scale. Group I demonstrated statistically significant improvements in receptive and expressive language ages (p < .001) and total social skills scores (p < .001) compared to Group II. Crucially, these therapeutic gains were sustained at the 3-month follow-up with no significant deterioration (p > .05). VR-based communication rehabilitation is a highly effective and sustainable intervention for supplementing language and social skills in young children with ASD. Its integration into clinical practice provides a scalable, engaging and culturally adaptable platform for neurodevelopmental care.
