了解典型发育的儿童是否以及如何适应不同的功能任务，可以为更有针对性的康复干预设计提供信息，以改善运动障碍儿童的上肢功能。这项前瞻性研究比较了典型发展中学龄儿童的饮水、进食和双侧伸手任务的时间和协调。在71名平均年龄为8.77 ± 0.48岁的儿童中测量了手运动的平均速度、直线度和平滑度。重复测量的线性混合模型比较了任务的变量，达到的阶段，任务X阶段的相互作用，占主导地位的手与非占主导地位的手。有显着的任务和阶段的主效应，显着的任务x阶段的相互作用（p < 0.05），和优势和非优势手之间的直的显着差异。手的动作是最快和最顺利的达到吃的任务，最不直的双边达到任务。手的动作也直的对象运输阶段比的伸展和撤回阶段。这些结果表明，具有典型发育的儿童会根据他们正在执行的任务改变他们接触的时间和协调。这些结果可以为针对手臂和手部功能的康复干预设计提供信息。
Understanding whether and how children with typical development adapt their reaches for different functional tasks could inform a more targeted design of rehabilitation interventions to improve upper extremity function in children with motor disabilities. This prospective study compares timing and coordination of a reach-to-drink, reach-to-eat, and a bilateral reaching task in typically developing school-aged children. Average speed, straightness, and smoothness of hand movements were measured in a convenience sample of 71 children, mean age 8.77 ± 0.48 years. Linear mixed models for repeated measures compared the variables by task, phases of the reach, task x phase interactions, and dominant versus non-dominant hands. There were significant main effects for task and phase, significant task x phase interactions (p < 0.05), and a significant difference between the dominant and non-dominant hand for straightness. Hand movements were fastest and smoothest for the reach-to-eat task, and least straight for the bilateral reaching task. Hand movements were also straighter in the object transport phases than the prehension and withdrawal phases. These results indicate that children with typical development change their timing and coordination of reach based on the task they are performing. These results can inform the design of rehabilitation interventions targeting arm and hand function.
