PMID 32945221WHAT IT FOUND
A 10-week group program improved dynamic balance but not static balance in 12 children with DCD.
Nine participants improved their dynamic control scores. The lack of a control group and small sample size mean this is preliminary evidence, not proof the program works.
Key findings
01Dynamic postural control scores improved significantly after the intervention, while static postural control scores did not change.
02Nine of the twelve participants showed improvement in dynamic control, with responders improving by 3% to 37%.
03The study had no control group and a very small sample, limiting conclusions about efficacy.

What it does not show
No control group, so improvements could be due to natural development, practice effects, or placebo. Very small sample size (n=12), limiting statistical power and generalizability. No follow-up assessment to determine if improvements were retained over time. Criterion C for DCD diagnosis (motor skills substantially below age expectations) was not formally assessed. Improvements were isolated to the specific dynamic task used; transfer to real-life skills or static balance was not demonstrated.
The easy way to misread this
Do not assume this program is proven effective. The study lacked a control group, so the observed improvements in dynamic balance could be due to natural growth or repeated testing rather than the intervention itself. Additionally, static balance did not improve, indicating the effects are not broad.
