Effectiveness of Cognitive Orientation to Occupational Performance intervention in improving motor skills of children with developmental coordination disorder: A randomized waitlist-control trial.

PMID 35466705WHAT IT FOUND
Children with developmental coordination disorder improved their self-rated motor performance and satisfaction, and these gains lasted three months.
However, they did not show immediate improvement in general motor skills on standardized testing. Children with co-occurring ADHD did not show this delayed general transfer.
Key findings
01Self-rated performance and satisfaction improved significantly, with 83% to 92% of children showing clinically significant gains.
02General motor skill ability on standardized testing did not improve immediately after intervention.
03Children with DCD alone showed delayed improvement in general motor skills at follow-up, but those with co-occurring ADHD did not.

What it does not show
The study used a waitlist control, which does not account for maturation or other non-specific effects as effectively as an active behavioral comparator. The BOT-2 may not be sensitive enough to capture immediate transfer of learning to foundational motor skills. The effect of ADHD medications on the results could not be controlled for in the statistical analysis. Follow-up data was limited by fewer participants and the absence of COPM data at the follow-up assessment.
Declared interests
The authors declared no potential conflicts of interest. The study was funded by the Canadian Institutes of Health Research and other academic and foundation grants.
The easy way to misread this
Do not assume that CO-OP intervention will immediately improve standardized general motor skill scores on tests like the BOT-2. The study found no immediate transfer, and delayed transfer was only seen in children with DCD alone, not those with co-occurring ADHD.
