Effects of exercise interventions on motor coordination in children with developmental coordination disorder (DCD): A systematic review and meta-analysis.

Researchers pooled data from 24 studies involving over 1,600 children with developmental coordination disorder (DCD), which is a condition affecting motor skill development, to see whether exercise-based interventions actually work. The evidence suggests they do: exercise appeared to produce meaningful improvements across several areas including overall motor coordination, fine motor control, hand-eye coordination, and balance. The effect on hand-eye coordination and overall coordination was somewhat larger than the effect on fine motor skills and balance.

However, one striking finding emerged from the data: when researchers looked at how the amount of intervention time affected outcomes, children seemed to improve more when they received shorter or fewer sessions rather than longer programmes. This counterintuitive result suggests that the relationship between how much therapy you give and how much children gain is more complicated than simply doing more.

This research looked at whether exercise and movement-based therapy helps children with coordination difficulties. Across many different studies, children who took part in these programmes did show improvements in their ability to coordinate movements, control their hands precisely, and keep their balance.

What the research cannot yet tell us is exactly which type of exercise works best, or how long the programmes need to be to work well. In fact, the data hint that sometimes less intensive programmes were linked with better results, which was unexpected and suggests there is still a lot to learn about what makes these interventions work best for individual children.

This meta-analysis consolidates evidence that exercise interventions produce medium to large effect sizes for motor coordination (g = 1.06) and hand-eye coordination (g = 1.12) in children with DCD, with smaller but still meaningful effects on fine motor skills and balance. The heterogeneity was substantial across most outcomes (I² ranging from 32% to 87%), reflecting considerable variation in how studies were conducted and which children they involved.

Intervention setting, approach type, and study design all emerged as moderating factors, suggesting that context and methodology matter when interpreting results. The inverse relationship between session duration or total number of sessions and improvements in fine motor skills is particularly noteworthy and warrants careful interpretation, as it may reflect publication patterns, selection bias, or genuine dose-response effects that are currently unclear.

The authors themselves acknowledge that more rigorous comparative trials are needed to isolate which specific interventions or dosing patterns produce the best outcomes.
