The present study examined the effects of daily activities of the hands on finger motor function in older adults. Maximum tapping frequency with each finger during single-finger tapping and alternate movements of index–middle, middle–ring, and ring–little finger pairs during double-finger tapping were compared between older adults who used their hands actively in their daily lives and those who did not. The active participants had significantly faster tapping rates for the ring finger in the single-finger tapping and the middle–ring finger pair in the double-finger tapping than did the inactive participants. Thus, daily activity of the hands in older adults could be effective at preventing the loss of dynamic motor function in individual fingers, especially with greater difficulty in movement, resulting from the degeneration with age.

本研究检查了老年人日常活动对手指运动功能的影响。比较了在日常活动中主动使用手的老年人与那些在日常生活中主动使用手的老年人之间的单指敲击过程中每个手指的最大敲击频率以及双指敲击过程中的食指，中指，无名指和无名指对的交替运动。谁没有。与非活动参与者相比，活动参与者的单指敲击无名指敲击速度和双手指敲击中指的无名指敲击速度显着提高。因此，老年人的手的日常活动可以有效地防止个体手指的动态运动功能丧失，尤其是随着年龄的增长而导致运动困难更大的手指。
