Our study aimed to analyze movement control strategies using predefined criteria for amplitude and differences in these strategies between children with and without DCD. Children with (n = 28) and without DCD (n = 15) were included. A video-observation-tool was used to score the moving body parts during a Wii Fit slalom task over multiple time points. Two-step cluster analysis was used to extract distinct movement strategies. Two different movement strategies were identified that were independently validated by a measure of task performance and a subjective mark of quality of the movement. Initial differences between groups and changes over time toward the more successful strategy were found in both groups, albeit in a different percentage. This study shows that the more efficient movement strategy is seen in the majority of the TD children and only in a small number of children with DCD, even after practice.

有和没有发育协调障碍的儿童在动态平衡任务中的运动控制策略。

我们的研究旨在使用预先定义的标准来分析运动控制策略，以了解有无DCD的儿童之间这些策略的幅度和差异。纳入有（n = 28）和没有DCD（n = 15）的儿童。在Wii Fit激流回旋任务中的多个时间点上，使用视频观察工具对运动的身体部位进行评分。两步聚类分析用于提取不同的运动策略。确定了两种不同的运动策略，分别通过任务绩效和运动质量的主观标记来独立验证。两组之间都存在最初的差异，并且随着时间的推移朝着更成功的策略的变化，尽管百分比不同。
