Eight 10-year-old children manifesting movement co-ordination problems (MCP), as assessed by the Movement Assessment Battery for Children (MABC), and a matched control group of eight children of a similar age without such problems, were required to carry out a laboratory ball-catching task. The task was constrained in such a way as to allow separate kinematic analyses of reaching (Experiment 1) and grasping (Experiment 2) subactions. Significant differences between the groups, in favour of the control group, were found with respect to both spatial and temporal performance in intercepting the moving ball. The MCP children were shown to initiate reaching movements later and to initiate grasping movement of the fingers earlier in time than the controls. MCP children also made more spatial errors. These findings are discussed in the context of the distinction made in the neuropsychological literature between proximal and distal motor control systems and the visual perceptual system.
通过儿童运动评估量表（MABC）评估，八名表现出运动协调问题（MCP）的10岁儿童，以及一个由八名年龄相仿但无此类问题的儿童组成的匹配对照组，被要求完成一项实验室接球任务。该任务的设计方式允许分别对伸手接球（实验1）和抓握（实验2）子动作进行运动学分析。在拦截移动球的空间和时间表现方面，发现两组之间存在显著差异，对照组表现更优。结果显示，与对照组相比，患有MCP的儿童伸手接球动作启动较晚，手指抓握动作启动较早。患有MCP的儿童在空间上也出现了更多错误。本文结合神经心理学文献中对近端和远端运动控制系统以及视觉感知系统的区分，对这些发现进行了讨论。
