Abstract

Despite its popularity, there is a lack of standardization when assessing postural control. This study aimed to suggest how many trials should be used when assessing young adults’ postural control with a specific single-task and dual-task quiet stance protocol. Two groups of 15 participants performed 20 trials of 60 s (feet together, eyes open) with or without a dual-task. The number of trials needed to obtain two consecutive intra-class correlation coefficients (ICC(2,k)) ≥0.900 was then assessed for seven center of pressure variables. Although inconsistency was observed between variables and tasks, five trials seems to be a good compromise.

摘要

尽管它很受欢迎，但是在评估姿势控制时仍缺乏标准化。这项研究的目的是建议在评估具有特定单任务和双任务安静姿态方案的年轻人的姿势控制时应使用多少次试验。两组（每组15名参与者）在执行或不执行双重任务的情况下进行了20次60 s（合脚，睁开眼睛）的试验。然后评估七个压力中心变量，以获得两个连续的组内相关系数（ICC（2，k））≥0.900所需的试验次数。尽管在变量和任务之间观察到不一致，但是五个试验似乎是一个很好的折衷方案。
