Abstract：
BACKGROUND: Finger tapping impairment and frailty share overlapping pathophysiology and symptoms in older adults, however, the relationship between each other has not been previously studied.
OBJECTIVE: To investigate how finger tapping movements correlate with frail status in older Japanese adults.
METHODS: Data were from a cross-sectional study called the Cognition and Activity in Rural Environment of Hokkaido Senior Survey 2018. A total of 244 community-dwelling older adults (mean age 75.3 years) were included.
METHODS: Participants underwent physical examinations, gait and finger tapping tests, and completed self-administered questionnaires. Frailty was assessed using Fried\'s frailty phenotype, and factor analysis was conducted to extract relevant finger tapping factors. Multinomial logistic regression was employed to analyze associations, generating adjusted odds ratios.
RESULTS: Of the participants, 18 were frail, and 145 pre-frail. Analysis identified three distinct finger tapping patterns: \"Range of Motion - Nondominant Hand,\" \"Variability - Dominant Hand - Anti,\" and \"Variability - Nondominant Hand - Anti.\" These patterns showed significant associations with aspects of Fried\'s frailty phenotype, particularly low physical activity (P = 0.002), weakness (P = 0.003), and slowness (P = 0.004). A larger range of motion in the nondominant hand correlated with a lower frailty risk (Odds Ratio: 0.09, 95% CI: 0.02-0.46), while higher variability in the same hand increased the risk of pre-frailty (Odds Ratio: 2.19, 95% CI: 1.09-4.39).
CONCLUSIONS: Finger tapping movements are significantly associated with frailty status as determined by Fried\'s phenotype. The findings underscore the importance of further longitudinal studies to understand the relationship between motor function and frailty.

摘要：
背景：在老年人中，手指轻触障碍和虚弱具有重叠的病理生理学和症状，然而,彼此之间的关系以前没有研究过。
目的：调查日本老年人手指敲击动作与虚弱状态的关系。
方法：数据来自2018年北海道高级调查的一项名为“农村环境中的认知和活动”的横断面研究。总共包括244名社区居住的老年人（平均年龄75.3岁）。
方法：参与者接受了体检，步态和手指敲击测试，并完成了自我管理问卷。使用Fried的虚弱表型评估虚弱，并进行因子分析,提取相关手指敲击因子。采用多项逻辑回归分析关联，生成调整后的赔率比。
结果：在参与者中，18人很虚弱，和145个脆弱的人。分析确定了三种不同的手指敲击模式：“运动范围-非优势手，\"\"变异性-优势手-反，“和”变异性-非显性手-反。“这些模式显示出与Fried的脆弱表型方面的显著关联，特别是低体力活动（P=0.002），弱点（P=0.003），和缓慢（P=0.004）。非优势手的较大运动范围与较低的虚弱风险相关（赔率：0.09，95％CI：0.02-0.46），而同一手较高的变异性增加了前期虚弱的风险(赔率比:2.19,95%CI:1.09-4.39)。
结论：手指轻敲动作与Fried的表型所确定的虚弱状态显著相关。这些发现强调了进一步纵向研究以了解运动功能与虚弱之间关系的重要性。
