Insights on action observation and imitation abilities in children with Developmental Coordination Disorder and typically developing children.
A 15-minute watch-and-copy task spots movement imitation deficits in children with DCD and points to why daily living skills lag.
01Research in Context
What this study did
The team built a 15-minute test that watches how well kids copy moves.
They gave it to children with Developmental Coordination Disorder and to same-age peers.
Each child watched short actions and then tried to repeat them while the scorer counted correct parts.
What they found
Kids with DCD scored much lower on both watching and copying moves.
Poor scores lined up with weaker motor skills and harder daily tasks like buttoning or using scissors.
The quick test picked out the children who struggle most.
How this fits with other research
de Castro Ferracioli et al. (2014) also saw shaky motor timing in DCD with a jump-and-clap task.
Rosenblum et al. (2013) found slow Interactive Metronome scores in the same group.
Together these papers show DCD is not just clumsy arms and legs; the brain’s copy-and-paste system for movement is off as well.
Zhou et al. (2018) looked inside the brain and found dampened motor cortex activity during imagery in young adults with DCD.
That neuro study helps explain why the kids in Eleonora’s paper could not translate what they saw into smooth action.
Why it matters
You now have a fast, no-equipment screen for imitation gaps.
Run the 15-minute protocol before writing goals; if the child scores low, add action-observation warm-ups and extra visual cues to your sessions.
Pair the results with earlier findings on timing and grip force to build a full picture of why motor skills stall.

03Original abstract
BACKGROUND: Children with Developmental Coordination Disorder (DCD) face difficulties in motor learning. Action observation and imitation are strategies frequently used to teach motor skills. AIMS: (1) To study action observation and imitation abilities in children with DCD compared with typically developing peers with a new protocol. (2) To gain insights in the relation between action observation, imitation, motor performance and activities of daily living (ADL). METHOD: Twenty-one children with DCD (mean age 7 years 9 months, range 6-10 years) and 20 age-matched controls (mean age 7 years 8 months, range 6-10 years) were included. A newly developed protocol was used for testing action observation and imitation proficiency. Motor performance were evaluated with the Movement Assessment Battery for Children-2. ADL were investigated with DCD Questionnaire'07. RESULTS: Children with DCD presented significantly lower action observation (p = .037) and imitation abilities (p < .001) than peers. Worse action observation and imitation abilities were related to lower motor performance and ADL skills and a younger age. Non-meaningful gestures imitation proficiency had predictive value for global motor performance (p = .009), manual dexterity (p = .02) and ADL (p = .004). CONCLUSIONS: The new protocol for action observation and imitation abilities can be helpful for detecting motor learning difficulties and for delineating new opportunities for motor teaching approaches in children with DCD.
