This study examined the association between spontaneous finger tapping and cognitive function, with a detailed analysis of the two main phases of finger tapping, the touch-phase and the off-phase. 170 elderly patients (83 men, 87 women; M age = 82.1 yr., SD = 6.2) underwent cognitive assessment including the Mini-Mental State Examination, a forward digit span test, and 15 sec. of finger tapping. Results indicated a significant increase in the length and variability of the finger-touch phase among participants with mild cognitive impairment or dementia compared to participants with no cognitive impairment, suggesting a relationship between finger tapping and attention, short-term memory, and cognitive diagnosis. Pattern classification analyses on the finger tapping parameters indicated a specificity of 0.91 and sensitivity of 0.52 for ruling out cognitive impairment.
本研究调查了自发手指敲击与认知功能之间的关联，并对手指敲击的两个主要阶段，即接触阶段和离开阶段进行了详细分析。170名老年患者（83名男性，87名女性；平均年龄 = 82.1岁，标准差 = 6.2）接受了认知评估，包括简易精神状态检查表、顺背数字广度测验和15秒的手指敲击测试。结果表明，与无认知障碍的参与者相比，轻度认知障碍或痴呆参与者的手指接触阶段的时长和变异性显著增加，这表明手指敲击与注意力、短期记忆和认知诊断之间存在关联。对手指敲击参数进行的模式分类分析表明，排除认知障碍的特异性为0.91，敏感性为0.52。
