Executive Functions Rehabilitation in Premature Children Using an Adaptive Motion-Interaction Videogame Platform: A Randomized Controlled Trial.

Abstract

Background: Premature children are at increased risk of executive functions (EF) deficits and these difficulties persist into adolescence and adulthood, potentially undermining their development and academic achievements. The aim of the present randomized controlled trial (RCT) is to evaluate the efficacy of the Intendu trainer, an adaptive virtual reality platform, at ameliorating EF in preterm children. Methods: A single-center, RCT was conducted. The intervention group was exposed to game session with the Intendu software in addition to the standard of care in use in our center. The main outcome was the proportion of children with a 10-point increase in the processing speed quotient as measured by WPPSI-III after 4 weeks from the baseline assessment. Results: Forty-seven children born before 36 + 5 weeks were randomized to the experimental (n = 24) or control arm (n = 23). Five children were lost to follow-up. Thirteen of 23 children (56%) reached the main outcome in the experimental group and 5 of 19 (26%) in the control group (P = 0.049, per-protocol analysis) with an absolute benefit increase (ABI) of 30% reconfirmed by the intention-to-treat analysis (P = 0.022, ABI of 32%). Conclusion: Intendu brain-trainer showed promising short-term results on EF in pre-term children, however, larger studies with longer periods of follow-up are warranted to better investigate the role of this or similar technology in promoting better EF in preterm children.
