Despite the growing concern regarding a potential increase in the number of older adults with frailty owing to an aging global population, the characteristics of bimanual coordination in such older adults remain unclear. This study aimed to compare bimanual coordinated movements among community-dwelling older adults with frailty, pre-frailty, and robust health and identify the specific characteristics of these movements in older adults with frailty.
Participants were categorized into frail, pre-frail, and robust groups based on Kihon Checklist scores. They performed bimanual coordination tasks in-phase (tapping the thumb and index finger together as fast as possible) and anti-phase (alternating the movement between the left and right fingers), and the task parameters were compared among the groups.
The total travel distance during the anti-phase task in the frail group was significantly shorter than that in the robust group. However, all three groups showed lower finger dexterity during the anti-phase task than in the in-phase task and the left hand than in the right hand.
Older adults with frailty exhibit less movement during bimanual coordination tasks than robust older adults, suggesting that such tasks may be useful tools for assessing frailty.
尽管全球人口老龄化导致体弱老年人数量可能增加这一问题日益受到关注，但此类老年人的双手协调特征仍不明确。本研究旨在比较社区居住的体弱、虚弱前期和健康状况良好的老年人之间的双手协调运动，并确定体弱老年人这些运动的具体特征。
根据基宏检查表评分将参与者分为体弱组、虚弱前期组和健康组。他们进行了双手协调任务，包括同相（尽可能快地同时轻拍拇指和食指）和反相（左右手指交替运动），并比较了各组之间的任务参数。
体弱组在反相任务中的总移动距离明显短于健康组。然而，所有三组在反相任务中的手指灵活性均低于同相任务，且左手低于右手。
体弱老年人在双手协调任务中的运动比健康老年人少，这表明此类任务可能是评估体弱状况的有用工具。
