[Purpose] This study aimed to investigate the influence of seat-forward tilt angles on improving upper limb dexterity in seated tasks and to contribute to the development of seating strategies. [Participants and Methods] Seventeen healthy men (age, 20.0 ± 0.5 years; height, 175.1 ± 4.9 cm; and body weight, 63.8 ± 6.7 kg) participated in this study. The forward tilt angles of the seat were set at 0°, 15°, and 30°, with knee pads used in all conditions. The Purdue Pegboard task was used to assess upper limb dexterity, with participants inserting pins into holes in the board for 60 s. Additionally, a visual analog scale was used to evaluate the perceived ease of the task. [Results] The Purdue Pegboard task scores were 30.0 ± 2.5, 30.6 ± 2.7, and 32.5 ± 2.9 for the 0°, 15°, and 30° conditions, respectively. The visual analog scale scores were 75.3 ± 9.8, 76.4 ± 14.6, and 84.1 ± 11.1 for the 0°, 15°, and 30° conditions, respectively. Both measurements showed significantly higher values under the 30° condition than under the other two conditions. [Conclusion] These results suggest that a tilt angle of 30° provides the most significant ease and upper limb dexterity.
[目的] 本研究旨在探讨座椅前倾角度对改善坐姿任务中上肢灵活性的影响，并为座椅策略的发展做出贡献。[参与者与方法] 17名健康男性（年龄20.0±0.5岁；身高175.1±4.9厘米；体重63.8±6.7千克）参与了本研究。座椅的前倾角度设定为0°、15°和30°，所有条件下均使用护膝。使用普渡钉板任务评估上肢灵活性，参与者在60秒内将钉子插入板上的孔中。此外，使用视觉模拟量表评估任务的感知难易程度。[结果] 在0°、15°和30°条件下，普渡钉板任务的得分分别为30.0±2.5、30.6±2.7和32.5±2.9。在0°、15°和30°条件下，视觉模拟量表的得分分别为75.3±9.8、76.4±14.6和84.1±11.1。两项测量结果均显示，30°条件下的值显著高于其他两个条件。[结论] 这些结果表明，30°的倾斜角度能带来最显著的轻松感和上肢灵活性。
