Kinematic assessments of the upper limb during activities of daily living (ADLs) are used as an objective measure of upper limb function. The implementation of ADLs varies between studies; whilst some make use of props and define a functional target, others use simplified tasks to simulate the movements in ADLs. Simulated tasks have been used as an attempt to reduce the large movement variability associated with the upper limb. However, it is not known whether simulated tasks replicate the movements required to complete ADLs or reduce movement variability. The aim of this study is to evaluate the use of simulated tasks in upper limb assessments in comparison to functional movements. Therefore answering the following questions: Do simulated tasks replicate the movements required of the upper limb to perform functional activities? Do simulated tasks reduce intra- and inter-subject movement variability? Fourteen participants were asked to perform five functional tasks (eat, wash, retrieve from shelf, comb and perineal care) using two approaches: a functional and a simulated approach. Joint rotations were measured using an optoelectronic system. Differences in movement and movement variability between functional and simulated tasks were evaluated for the thorax, shoulder, elbow/forearm and wrist rotations. Simulated tasks did not accurately replicate the movements required for ADLs and there were minimal differences in movement variability between the two approaches. The study recommends the use of functional tasks with props for future assessments of the upper limb.
在日常生活活动（ADL）期间对上肢进行运动学评估，被用作上肢功能的客观测量方法。不同研究中ADL的实施方式有所不同；有些研究使用道具并定义一个功能目标，而其他研究则使用简化任务来模拟ADL中的动作。模拟任务已被用于尝试减少与上肢相关的较大运动变异性。然而，尚不清楚模拟任务是否能复制完成ADL所需的动作或减少运动变异性。本研究的目的是评估与功能性动作相比，模拟任务在上肢评估中的应用。因此回答以下问题：模拟任务是否能复制上肢执行功能性活动所需的动作？模拟任务是否能减少受试者内和受试者间的运动变异性？14名参与者被要求使用两种方法执行五项功能性任务（进食、洗漱、从架子上取物、梳头和会阴护理）：功能性方法和模拟方法。使用光电系统测量关节旋转。针对胸部、肩部、肘部/前臂和腕部旋转，评估功能性任务和模拟任务之间的运动差异和运动变异性。模拟任务不能准确复制ADL所需的动作，并且两种方法之间的运动变异性差异极小。该研究建议在未来的上肢评估中使用带有道具的功能性任务。
