To compare the nature and extent of inter and intralimb coupling during two-handed catching and the effect of manipulating task constraints in children with Developmental Coordination Disorder (DCD) and their typically developing peers (AMC).
Twenty children aged 7 - 10 years, ten with DCD and 10 AMC attempted to catch a ball ten times in condition 1 (C1), ball to the midline; condition 2 (C2), ball to the left shoulder and condition 3 (C3), ball to the right shoulder. Both 3D kinematic data and video data were collected.
Children with DCD caught fewer balls than the AMC children, regardless of age or condition (p <or= 0.001). Children with DCD demonstrated a higher degree of linkage between limbs in C1 and a lower degree of between limb coupling in C2 and C3 when compared to the AMC (p <or= 0.05). Differences between the AMC7 - 8 and AMC9 - 10 group were found with respect to interlimb coupling.
The influence of manipulating task constraints and the individual nature of children with DCD must be considered by those involved in rehabilitation. By doing so, children with DCD may search for appropriate motor solutions to many functional movement tasks required for everyday life.
比较发育性协调障碍（DCD）儿童及其发育正常的同龄人（AMC）在双手接球过程中肢体间和肢体内部耦合的性质和程度，以及操纵任务限制的影响。
20名7至10岁的儿童，其中10名患有DCD，10名发育正常，在条件1（C1）中，球抛向身体中线；条件2（C2）中，球抛向左肩；条件3（C3）中，球抛向右肩，分别尝试接球10次。同时收集三维运动学数据和视频数据。
无论年龄或条件如何，患有DCD的儿童接住的球比发育正常的儿童少（p≤0.001）。与发育正常的儿童相比，患有DCD的儿童在C1中肢体间的联动程度更高，而在C2和C3中肢体间的耦合程度更低（p≤0.05）。在肢体间耦合方面，发现7 - 8岁发育正常的儿童组和9 - 10岁发育正常的儿童组之间存在差异。
参与康复的人员必须考虑操纵任务限制的影响以及DCD儿童的个体特性。这样做，患有DCD的儿童可能会为日常生活中许多功能性运动任务寻找合适的运动解决方案。
