Zwicker, Jill - Abstract

Aim:  The study’s purpose was to determine whether children with developmental coordination disorder (DCD) are able to demonstrate improved motor skill as evidenced by increased accuracy on a fine-motor tracing task and/or shifts in patterns of brain activation using functional resonance magnetic imaging.

Methods:  We compared motor performance and brain activation of 8 -12 year old children with DCD (n=6) with age-matched, typically-developing control children over four days of task practice.  The first day of practice and a retention test occurred in an MRI scanner.

Results:  Children with DCD made more errors and had highly variable performance of the fine-motor task compared to controls. During fMRI on Day 1, controls showed significantly more brain activation (t=3.17, p=.01) than the DCD group in motor-related areas (e.g., putamen, cerebellum); the DCD group showed significantly more activation in networks associated with attention and error detection (e.g., bilateral frontal gyri, anterior cingulated).
