Immersive Rehabilitation Therapy (MoveR) Improves Postural and Visuo-Attentional Skills in Children with ADHD: A Clinical Study

<b>Background:</b> Motor as well as attentional skills are deficient in children with attention deficit hyperactivity disorder (ADHD). The aim of the present study was to explore whether a short immersive rehabilitation therapy could improve motor and visuo-attentional capabilities in children with ADHD. <b>Methods:</b> Forty children with ADHD participated in this study; IQ-, sex- and age-matched children were splitted in two groups (G1 and G2) of twenty. An unpredictable random sequence was used to allocate a child to group G1 (trained group) or G2 (control group). Oculomotor and postural performance for both groups of children were objectively assessed twice (before and after 16 min) by using an eye tracker and platform. Group G1 only underwent 16 min of immersive rehabilitation therapy, while the control group (G2) had 16 min of resting. The immersive therapy consisted of performing physical movement while training visual discrimination, attention and spatial orientation skills. <b>Results:</b> After 16 min, significant improvements in the fixation area (<i>p</i> = 0.008) and in the number of catch-up saccades during pursuit eye movements (<i>p</i> < 0.001), as well as a smaller postural instability index (PII) (<i>p</i> < 0.001), were observed for the trained group (G1) only. <b>Conclusions:</b> These findings suggest that children with ADHD could benefit from a short immersive therapy to improve both visual-attention and motor performances. This new immersive therapy is a useful tool allowing a better integration of both visual and motor sensory inputs via the cortico/cerebellar network. Follow-up studies on a larger number of children with ADHD will be necessary to explore the eventual possible persistence of such a training effect and imaging works will help to understand where such adaptive mechanisms take place.
