Where Exactly Is the Therapist in Virtual Reality and Game-Based Rehabilitation Applications? A Randomized Controlled Trial in Children with Specific Learning Disability

Children with specific learning disability (SLD) experience problems in visual perception that influence academical skills and activities of daily living. Virtual reality and game-based rehabilitation applications are becoming increasingly popular in rehabilitation, including visual perception rehabilitation. However, the usage of commercially available and easily accessible games as intervention tools raises the question whether rehabilitation conducted with these games is really rehabilitation, or just casual gameplay. Therefore, we aimed to investigate the effects of a nonactively supervised (game-based intervention program [GIP]) and an actively supervised (therapist guided game-based intervention program [TGGIP]) on the visual perception skills of children with SLD. This study was designed as a single-blind randomized, controlled trial of a TGGIP on visual perception skills in children with SLD compared with the self-oriented, nonsupervised program (GIP). A total of 138 children with SLD participated in the study and were randomly divided into two groups (TGGIP and GIP). Children's visual perception skills were assessed with Motor-Free Visual Perception Test-3. Both groups showed significant improvements in visual perception after the intervention programs (
