[Purpose] Wearing shoes can be difficult for people who experience movement difficulties. This study aimed to compare young adults and senior adults while wearing shoes in order to quantify kinematic, physiological, and ergonomic points of variance. [Participants and Methods] Nine young adults (mean age, 21 years) and nine senior adults (mean age, 70 years) were included in the study. We investigated four postural combination of using hand and crossing legs used while wearing shoes: 1) time required to wear shoes, 2) the center of pressure point, 3) muscle activation within the right sartorius, the left rectus femoris, the gluteus maximus, and the internal oblique, and 4) the perceived ease of task performance via a numerical rating scale. [Results] The activities of the internal oblique and the gluteus maximus were significantly higher in senior adults than in young adults. Wearing shoes without using hands was associated with the highest value for the ease of performance among the four patterns for both groups. [Conclusion] Our results suggested that the muscles analyzed in this study were important for safety and postural maintenance while performing activities of daily living tasks in leg-raising processes in the sitting position, with lower level of muscle activity.
[目的] 对于行动不便的人来说，穿鞋可能会很困难。本研究旨在比较年轻人和老年人穿鞋时的情况，以量化运动学、生理学和人体工程学方面的差异点。[参与者与方法] 本研究纳入了9名年轻人（平均年龄21岁）和9名老年人（平均年龄70岁）。我们调查了穿鞋时使用手和交叉双腿的四种姿势组合：1）穿鞋所需时间，2）压力中心点，3）右缝匠肌、左股直肌、臀大肌和腹内斜肌内的肌肉激活情况，以及4）通过数字评分量表评估的任务执行难易程度。[结果] 老年人腹内斜肌和臀大肌的活动明显高于年轻人。在两组的四种模式中，不使用手穿鞋的表现轻松程度得分最高。[结论] 我们的结果表明，在坐姿抬腿过程中进行日常生活任务时，本研究中分析的肌肉对于安全性和姿势维持很重要，且肌肉活动水平较低。
