本研究旨在探讨手势表现在多大程度上取决于输入通道，以及是否有不同的姿势发展模式与儿童和非发展性协调障碍（DCD）。因此，研究了140名儿童-105名对照儿童（94名男性，11名女性）和35名患有DCD的儿童（29名男性，6名女性）的肢体姿势发育，分为三个年龄段：5至6岁，7至8岁和9至10岁。传递手势技能进行了调查，通过四种输入方式：模仿，视觉加触觉，视觉，和口头。结果表明，肢体姿势技能在正常发育的儿童遵循一个渐进的成熟模式：模仿，视觉加触觉，视觉路线出现成熟之前的口头路线，并出现可提前，使儿童能够执行正确的手势。DCD儿童在四种模式中的表现表明一般成熟延迟。当需要通过言语方式进行手势时，在使用感觉-运动信息以及将其整合到运动表征中方面存在特定缺陷。在言语模式中，患有DCD的儿童的表现始终比对照组的同龄人差，并且表现差异倾向于随着年龄的增长而增加而不是改善。
This study aimed to investigate the extent to which gesture performance depends on input modality and whether gestural development patterns differ in children with and without developmental coordination disorder (DCD). Therefore, development of limb gesture was studied in 140 children ‐105 control children (94 males, 11 females) and in 35 children with DCD (29 males, six females) divided into three age bands: 5 to 6 years, 7 to 8 years, and 9 to 10 years. Transitive gestural skills were investigated through four input modalities: Imitation, Visual plus Tactile, Visual, and Verbal. Results indicate that limb gestural skills in normally developing children follow a progressive maturation pattern: Imitation, Visual plus Tactile, and visual routes appear to mature before the verbal route and appear to be available earlier to enable the child to perform a correct gesture. The performance of children with DCD throughout the four modalities suggested a general maturational delay. When gestures were required through the Verbal modality, there was a specific deficit in using sensory‐motor information and in integrating it into a motor representation. In the Verbal modality, children with DCD performed consistently worse than their control peers and the difference in performance tended to increase rather than improve with age.
