Abstract

Background: Children with developmental coordination disorder (DCD) exhibit reduced interlimb coordination compared to typically developing children (TDC) during complex tasks like running, which requires dynamic postural control. However, the extent of interlimb coordination difficulties in DCD during tasks that demand minimal dynamic balance, such as self-paced and externally auditory-paced tasks, remains unclear. This study aimed to compare interlimb coordination and auditory-motor synchronization between children with DCD and TDC during a seated antiphase coordination task of the lower limbs, which has minimal postural control requirements. Methods: Twenty-one children with DCD and 22 TDC performed an antiphase knee flexion and extension task while seated, in three conditions (baseline silence, metronome discrete, and metronome continuous), for three minutes. The interlimb coordination, synchronization, and spatiotemporal movement parameters were analyzed using a mixed model analysis; Results: Children with DCD displayed less coordinated interlimb movements compared to TDC (p = 0.0140), which was the result of the greater variability in coordinating antiphase knee flexion-extension movements (p < 0.0001). No group differences in spatiotemporal movement parameters were observed. Children with DCD, compared to TDC, had a lower synchronization consistency to metronomes (p = 0.0155). Discrete metronomes enhanced interlimb coordination compared to the baseline silence condition (p = 0.0046); Conclusions: The study highlights an inferior interlimb coordination and auditory-motor synchronization in children with DCD compared to TDC. Implementing metronomes with a discrete temporal structure improved the interlimb coordination of both groups during the used fundamental seated interlimb coordination task, supporting theorical frameworks of event-based timing.

发育协调障碍儿童的肢体间协调和听觉运动同步:用听觉节拍器检查坐姿时膝关节的反相运动
背景:发育协调障碍(DCD)儿童在完成跑步等需要动态姿势控制的复杂任务时,肢体间的协调能力比发育正常儿童(TDC)要差。然而,发育协调障碍儿童在完成要求最小动态平衡的任务(如自定节奏和外部听觉节奏任务)时,肢体间协调困难的程度仍不清楚。本研究旨在比较 DCD 儿童和 TDC 儿童在完成对姿势控制要求最低的下肢坐姿反相协调任务时的肢体间协调性和听觉运动同步性。研究方法:21 名患有 DCD 的儿童和 22 名患有 TDC 的儿童在三种条件下(基线安静、节拍器不连续和节拍器连续),坐着进行了三分钟的反相位膝关节屈伸任务。采用混合模型分析法对肢体间的协调性、同步性和时空运动参数进行了分析:与 TDC 相比,DCD 儿童的肢体间动作协调性较差(p = 0.0140),这是协调反相膝关节屈伸动作的变异性较大的结果(p < 0.0001)。在时空运动参数方面没有观察到组间差异。与 TDC 儿童相比,DCD 儿童对节拍器的同步一致性较低(p = 0.0155)。与基线静默状态相比,离散节拍器增强了肢体间的协调性(p = 0.0046);结论:本研究强调,与 TDC 相比,DCD 儿童的肢体间协调性和听觉-运动同步性较差。在使用节拍器的基本坐姿肢体协调任务中,使用具有离散时间结构的节拍器可改善两组儿童的肢体协调能力,从而支持基于事件计时的理论框架。

期刊介绍: Children is an international, open access journal dedicated to a streamlined, yet scientifically rigorous, dissemination of peer-reviewed science related to childhood health and disease in developed and developing countries. The publication focuses on sharing clinical, epidemiological and translational science relevant to children’s health. Moreover, the primary goals of the publication are to highlight under‑represented pediatric disciplines, to emphasize interdisciplinary research and to disseminate advances in knowledge in global child health. In addition to original research, the journal publishes expert editorials and commentaries, clinical case reports, and insightful communications reflecting the latest developments in pediatric medicine. By publishing meritorious articles as soon as the editorial review process is completed, rather than at predefined intervals, Children also permits rapid open access sharing of new information, allowing us to reach the broadest audience in the most expedient fashion.
