The aim of this study was to estimate the finger-tapping rates and finger load capacities of eight fingers (excluding thumbs) for a healthy adult population and investigate the effects of various factors on tapping rate.
Finger-tapping rate, the total number of finger taps per unit of time, can be used as a design parameter of various products and also as a psychomotor test for evaluating patients with neurologic problems.
A 1-min tapping task was performed by 148 participants with maximum volitional tempo for each of eight fingers. For each of the tapping tasks, the participant with the corresponding finger tapped the associated key in the standard position on the home row of a conventional keyboard for touch typing.
The index and middle fingers were the fastest fingers for both hands, and little fingers the slowest. All dominant-hand fingers, except little finger, had higher tapping rates than the fastest finger of the nondominant hand. Tapping rate decreased with age and smokers tapped faster than nonsmokers. Tapping duration and exercise had also significant effect on tapping rate.
Normative data of tapping rates and load capacities of eight fingers were estimated for the adult population. In designs of psychomotor tests that require the use of tapping rate or finger load capacity data, the effects of finger, age, smoking, and tapping duration need to be taken into account.
The findings can be used for ergonomic designs requiring finger-tapping capacity and also as a reference in psychomotor tests.
本研究旨在估算健康成年人群八根手指（不包括拇指）的敲击速率和手指负荷能力，并研究各种因素对敲击速率的影响。
手指敲击速率，即单位时间内手指敲击的总数，可作为各种产品的设计参数，也可作为评估神经系统问题患者的心理运动测试。
148名参与者对八根手指中的每一根以最大自主节奏进行了1分钟的敲击任务。对于每个敲击任务，参与者用相应的手指在传统触摸打字键盘主键盘的标准位置敲击相关按键。
双手的食指和中指敲击速度最快，小指最慢。除小指外，优势手的所有手指敲击速率均高于非优势手最快的手指。敲击速率随年龄增长而降低，吸烟者敲击速度比不吸烟者快。敲击持续时间和运动对敲击速率也有显著影响。
估算了成年人群八根手指敲击速率和负荷能力的标准数据。在需要使用敲击速率或手指负荷能力数据的心理运动测试设计中，需要考虑手指、年龄、吸烟和敲击持续时间的影响。
研究结果可用于需要手指敲击能力的人体工程学设计，也可作为心理运动测试的参考。
