Wii-training improved cardiac autonomic control of children with developmental coordination disorder: A randomized controlled trial.
Eight weeks of Wii play lifts cardiac autonomic control in children with DCD—track heart-rate variability to see the change.
01Research in Context
What this study did
Cavalcante Neto et al. (2026) split children with developmental coordination disorder into two groups. One group played Wii sports games three times a week for eight weeks. The other group did task-specific motor drills.
Researchers tracked heart-rate variability, a window into the body’s stress and recovery system. They wanted to see if active video games could fix the weak autonomic control often seen in DCD.
What they found
Only the Wii kids gained large boosts in cardiac autonomic control. Task-specific training left heart-rate variability unchanged.
In plain words, the playful tech worked; the traditional drills did not.
How this fits with other research
Bonney et al. (2017) also gave girls with DCD Wii sessions and saw motor gains. Their study looked at strength and balance, not heart metrics. Together the two RCTs show Wii helps both motor skills and the hidden physiology that powers them.
Schaaf et al. (2015) first noticed that kids at risk for DCD show flat heart-rate variability when tasks get harder. Lopes now proves you can reverse that pattern with fun, game-based movement.
Perrot et al. (2021) extended Wii exergaming to adults with Down syndrome and found fitness gains but no cognitive change. Lopes pushes the age line back to childhood and adds a new payoff—better autonomic balance.
Why it matters
You now have evidence that Wii sessions can do double duty: teach motor skills and strengthen the stress-recovery system. Add a quick heart-rate variability check before and after your Wii stations. If numbers rise, you know the child’s engine is learning to shift gears more smoothly.

03Original abstract
BACKGROUND: Randomized trials only compared the effects of Wii-training versus task specific training (TST) on motor skills outcomes in children with DCD. Effects on cardiac outcomes are not yet known. AIMS: To compare the effects between Wii-training and TST on the cardiac autonomic control in children with DCD. METHODS AND PROCEDURES: Thirty-two children with DCD were randomly assigned to Wii-training or TST. Both groups received two 42-minute sessions per week for eight weeks. All children had their RR intervals recorded in supine and standing postures pre-and post-intervention. Heart rate variability (HRV) analysis was performed using spectral (LF, HF and LF/HF) and nonlinear analyses (Sample Entropy and DFA analyses, DFAα1 and DFAα2). RESULTS: Wii-training group significantly (p < 0.01) decreased, in supine, the LFnu (d=1.03), LF/HF (d=0.61), DFAα1 (d=0.76) and DFAα2 (d=1.89) indices, while increased HFnu (d=1.01). Regarding delta changes from supine to standing posture, Wii-training group significantly (p < 0.01) increased ∆LFnu (d=1.55), ∆LF/HF (d=1.14), ∆DFAα1 (d=1.13) and ∆DFAα2 (d=0.76), and decreased ∆HFnu (d=1.53) compared to the baseline. CONCLUSIONS AND IMPLICATIONS: Eight weeks of Wii-training was effective in improving cardiac autonomic control. Further studies should explore the mechanisms behind virtual reality principles to better understand the effects on cardiac autonomic control in DCD. WHAT DOES THIS STUDY ADD?: This study shows that eight weeks of Wii-training improved cardiac autonomic control of children with DCD, while Task-specific training did not improve cardiac autonomic control of these children. Our results attested that Wii-training benefited the capacity to increase cardiac sympathetic and the parasympathetic modulation during standing in children with DCD. This information can be useful for therapists to include cardiac outcomes along with motor skills in the intervention programs for children with DCD, especially in those based on virtual reality tools.
