Also, t-test and multivariate analysis of variance (MANCOVA) were used to test the hypotheses. All analyzes were performed using SPSS version 20 software at a significance level of p<0.05.
Conclusion: The results showed that virtual reality exercises have a positive effect on hand coordination skills in people with developmental coordination disorder.
