Arm activities are required for maintenance of self-care and independent living. This study aimed to investigate whether and to what extent arm activities of daily living (ADL) in chronic obstructive pulmonary disease (COPD) patients differ compared to healthy controls and the extent to which they perform arm ADL at a relatively higher upper limb muscle effort. Daily arm and leg activities were assessed using accelerometers in the home environment (COPD: n=21, healthy: n=24; part 1). The relative efforts of the trapezius, deltoid and biceps muscles were studied using electromyography during domestic arm ADL in a laboratory setting (COPD: n=17, healthy: n=15; part 2). After correction for walking time, the time spent on arm ADL was similar between COPD patients and healthy control subjects (p=0.52), while the intensity of arm activities was lower in COPD patients (p=0.041). In the laboratory setting, arm ADL were performed at a lower intensity by COPD patients, while the trapezius muscle effort was significantly higher during several arm ADL compared to healthy control subjects (p<0.05). COPD patients have a similar duration of arm ADL compared to healthy subjects after correction for walking time, but perform arm activities at a lower intensity. Moreover, patients perform some arm ADL at a relatively higher muscle effort.
手臂活动是维持自我护理和独立生活所必需的。本研究旨在调查慢性阻塞性肺疾病（COPD）患者的日常生活手臂活动（ADL）是否与健康对照组存在差异，以及他们在多大程度上以相对较高的上肢肌肉用力进行手臂 ADL。使用加速度计在家庭环境中评估日常手臂和腿部活动（COPD：n=21，健康：n=24；第 1 部分）。在实验室环境中，使用肌电图研究在家庭手臂 ADL 期间斜方肌、三角肌和肱二头肌的相对用力（COPD：n=17，健康：n=15；第 2 部分）。校正行走时间后，COPD 患者和健康对照组之间手臂 ADL 的时间相似（p=0.52），而 COPD 患者手臂活动的强度较低（p=0.041）。在实验室环境中，与健康对照组相比，COPD 患者进行手臂 ADL 的强度较低，而在几种手臂 ADL 中，斜方肌的用力明显更高（p<0.05）。校正行走时间后，COPD 患者与健康对照组相比，手臂 ADL 的持续时间相似，但手臂活动的强度较低。此外，患者在进行一些手臂 ADL 时相对用力较高。
