本研究的目的是调查是否可以识别发育性运动缺陷的亚型：具体来说，一种是运动规划障碍，其特征是手势表现和运动顺序缺陷，另一种是运动技能执行障碍，其特征是平衡和协调缺陷。受试者包括 102 名年龄在 6 岁至 10 岁 11 个月之间的儿童，其中 51 名被确定存在运动技能缺陷，51 名正常对照组。使用平衡、双侧协调、上肢协调、传递手势和运动序列测量的分层凝聚和迭代分区聚类分析揭示了四种亚型。一组表现出运动顺序缺陷，而另一组则表现出平衡、协调和手势表现缺陷。此外，第三组儿童在所有运动技能领域都表现出严重缺陷，最后一组与其他组相比没有运动缺陷。对学业、语言、视觉感知、视觉运动技能表现的检查显示，这四组人表现出不同的非运动表现模式。这些发现表明，在被贴上“笨拙”标签的儿童中可以识别出不同亚型的发育运动缺陷。
The purpose of this study was to investigate whether subtypes of developmental motor deficits could be identified: specifically, one with impairments in motor planning that would be characterized by deficits in gestural performance and motor sequencing and a second with impairments in the execution of motor skills that would be characterized by deficits in balance and coordination. Subjects included 102 children between the ages of 6 years and 10 years, 11 months, 51 who had been identified as displaying deficits in motor skills and 51 normal controls. Hierarchical-agglomerative and iterative partitioning cluster analyses using measures of balance, bilateral coordination, upper limb coordination, transitive gestures, and motor sequencing revealed four subtypes. One group displayed deficits in motor sequencing, whereas another demonstrated deficits in balance, coordination, and gestural performance. In addition, a third group of children showed severe deficits in all motor skill areas, and a final group had no motor deficits compared with the other groups. Examination of performance on measures of academic, language, visual-perceptual, visual-motor skills revealed that these four groups displayed different patterns of nonmotor performance. These findings suggest that different subtypes of developmental motor deficits can be identified among children who have been labeled ''clumsy.''
