[Purpose] The purpose of this study was to present control data on writing pressure, the amount of weight on the upper limb, joint angle, and the area of overlap from the sample in graphic tracing tasks, and to extract factors that affect pen-operating skills. [Participants and Methods] The participants included 35 healthy volunteers who performed 1-inch graphic tracing and writing. The measurements were recorded under two conditions as follows: strong and weak writing pressure tasks, and fast and careful writing speed tasks. [Results] In the writing pressure task, increase in pen pressure was accompanied by increase in hand pressure; however, the forearm pressure did not change. In the writing speed task, no significant difference in pressure was observed, except for a slight difference in writing pressure. The degree of variation in pen pressure and areas of overlap were greater in the fast task than in the careful task. Two multiple regression models revealed the contributing factors to pen-operating skills, both showing that the degree of variation in pen pressure was significantly involved. [Conclusion] The multiple regression analysis results showed that pen-operating skills can likely be evaluated, where the degree of variation in writing pressure is an index for deciding the effect of treatment intervention.
[目的]本研究旨在呈现图形追踪任务中样本的书写压力、上肢负重、关节角度和重叠面积的对照数据，并提取影响笔操作技能的因素。[参与者与方法]参与者包括35名健康志愿者，他们进行了1英寸的图形追踪和书写。测量在以下两种条件下进行记录：强书写压力任务和弱书写压力任务，以及快速书写速度任务和仔细书写速度任务。[结果]在书写压力任务中，笔压力增加伴随着手部压力增加；然而，前臂压力没有变化。在书写速度任务中，除了书写压力有轻微差异外，未观察到压力有显著差异。快速任务中笔压力的变化程度和重叠面积比仔细任务中的更大。两个多元回归模型揭示了笔操作技能的影响因素，两者均表明笔压力的变化程度有显著关联。[结论]多元回归分析结果表明，书写压力的变化程度是决定治疗干预效果的一个指标，据此有可能评估笔操作技能。
