Document Summary
Reading #1: brain activation of children with developmental coordination disorder (dcd) is different than peers: Children with dcd struggle to learn new motor skills, demonstrating more variable performance than typically developing (td) children. Purpose of study to determine whether patterns of brain activity differed between children w/ and w/o dcd while performing a motor task. Using fmri, measured brain activation patterns in 7 children w/ dcd, and 7 age- matched td (8-12 years) during a fine-motor, trail-tracing task. Results suggest dcd group relied on visuospatial processing to complete task. Td group demonstrated significantly more activation in: left precuneus, left superior frontal gyrus, right superior temporal gyrus/insula, left inferior frontal gyrus, left postcentral gyrus. These areas associated with spatial processing, motor control & learning, and error processing. Children with dcd activate different brain regions from td children when performing same trail-tracing task. Significantly interferes with activities of daily-living and school performance.
