本研究旨在阐明在发育协调障碍（DCD）儿童中观察到的纠正飞行动作的能力下降是否反映了发育不成熟或偏离典型轨迹。18名患有DCD的儿童（812岁），18名年龄匹配的对照组和12名年龄较小的对照组（57岁）完成了双步到达任务。与年长的对照组相比，患有DCD的儿童和年轻的对照组在运动开始时，当目标意外移动时，表现出相似的延迟到达，并且同样缓慢地纠正他们的到达轨迹。这些结果表明，DCD的在线控制受损反映了发育不成熟，可能涉及顶叶-小脑皮质。
The present study aimed to clarify whether a reduced ability to correct movements in-flight observed in children with developmental coordination disorder (DCD) reflects a developmental immaturity or deviance from the typical trajectory. Eighteen children with DCD (812 years), 18 age-matched controls, and 12 younger controls (57 years) completed a double-step reaching task. Compared to older controls, children with DCD and younger controls showed similarly prolonged reaching when the target unexpectedly shifted at movement onset and were equally slow to correct their reaching trajectory. These results suggest that impaired online control in DCD reflects developmental immaturity, possibly implicating the parietal-cerebellar cortices.
