Motion analysis during activities of daily living has been conducted in numerous studies. However, information is lacking regarding age-related differences that affect clinical assessment and treatment goals. This study aimed to examine the effect of age on kinematics during activities of daily living. Three-dimensional motions of the shoulder, elbow, neck, and trunk of 12 younger adults (age, 29.8 ± 5.4 years; 7 men and 5 women) and 10 older adults (age, 69.5 ± 4.9 years; 6 men and 4 women) were measured during the acts of reaching for a table, bringing a glass to the mouth for drinking, wiping the buttocks, tying shoelaces, washing hair, washing the axilla, reaching for a high shelf, and reaching for the floor. The ranges of motion and sequential joint angles were compared between age groups by using discrete analysis and statistical parametric mapping, respectively. The ranges of motion of all joint angles in older and younger adults were comparable in the drinking, washing hair, washing the axilla, and reaching for the floor tasks. Statistical parametric mapping indicated that older adults had significantly poorer neck extension than did younger adults during the drinking (67-92% cycle time) and tying shoelaces (64-95% cycle time) tasks. Kinematics were mostly maintained in healthy older adults during activities of daily living. However, reduced motions were confirmed later during some tasks. The results indicated that existing knowledge combined with the current findings, which take age into account, could be used in clinical settings to assess the kinematics of activities of daily living and set treatment goals.
在众多研究中都进行了日常生活活动中的运动分析。然而，关于影响临床评估和治疗目标的年龄相关差异的信息却很缺乏。本研究旨在探讨年龄对日常生活活动中运动学的影响。在伸手够桌子、将杯子举到嘴边喝水、擦拭臀部、系鞋带、洗头、清洗腋窝、够高架子以及够地板等动作过程中，测量了12名年轻成年人（年龄29.8±5.4岁；7名男性和5名女性）和10名年长成年人（年龄69.5±4.9岁；6名男性和4名女性）的肩部、肘部、颈部和躯干的三维运动。分别通过离散分析和统计参数映射比较了不同年龄组之间的运动范围和连续关节角度。在喝水、洗头、清洗腋窝和够地板任务中，年长和年轻成年人所有关节角度的运动范围相当。统计参数映射表明，在喝水（周期时间的67 - 92%）和系鞋带（周期时间的64 - 95%）任务中，年长成年人的颈部伸展明显比年轻成年人差。在日常生活活动中，健康年长成年人的运动学大多得以维持。然而，在一些任务后期证实运动有所减少。结果表明，结合现有知识与当前考虑年龄因素的研究结果，可用于临床环境中评估日常生活活动的运动学并设定治疗目标。
