Virtual reality-based interventions improve balance skills in children with developmental coordination disorder: systematic review and meta-analysis.

Purpose: Virtual reality-based interventions (VRBI) are a gamified approach to therapy that can improve balance and motor skills in children diagnosed with Developmental Coordination Disorder (DCD). The aim was to investigate the effectiveness of VRBI in improving balance and motor skills in children with DCD.

Methods: According to PRISMA guidelines, meta-analyses were conducted by searching randomized controlled trials (RCTs) that investigated the effect of VRBI on balance and motor skills in children with DCD. The global search was carried out in PubMed, SCOPUS, WOS, CINAHL and PEDro during the period from April 1 to 24, 2024, without publication date restrictions. Standardized mean difference (SMD) and its 95% confidence interval (95%CI) was calculated as the pooled effect measure.

Results: Nine RCTs, with a moderate mean methodological quality (5.11 points in PEDro) providing data from 266 participants, were included. All studies included used non-immersive virtual reality (NIVR) devices to carry out the VRBI. Meta-analyses revealed that NIVR was effective in increasing balance (SMD = 0.4; 95%CI 0.09-0.71), as well as running and agility skills (SMD = 0.45; 95%CI 0.03-0.87). However, no statistical differences were found in improving motor skills.

Conclusions: Findings reported in this meta-analysis support that VRBI that use NIVR devices can be effective in improving balance in children with DCD.
