Accurate assessment of the amount and intensity of physical activity in daily life is considered very important due to the close relationship between physical activity level, health, disability and mortality. For this reason, assessment of physical activity in daily life has gained interest in recent years, especially in sedentary populations, such as patients with chronic obstructive pulmonary disease (COPD). The present article aims to compare and discuss the two kinds of instruments more commonly used to quantify the amount of physical activity performed by COPD patients in daily life: subjective methods (questionnaires, diaries) and motion sensors (electronic or mechanical methods). Their characteristics are summarised and evidence of their validity, reliability and sensitivity is discussed, when available. Subjective methods have practical value mainly in providing the patients' view on their performance in activities of daily living and functional status. However, care must be taken when using subjective methods to accurately quantify the amount of daily physical activity performed. More accurate information is likely to be available with motion sensors rather than questionnaires. The selection of which motion sensor to use for quantification of physical activity in daily life should depend mainly on the purpose of its use.
鉴于身体活动水平、健康、残疾和死亡率之间的密切关系，准确评估日常生活中的身体活动量和强度被认为非常重要。因此，近年来日常生活中身体活动的评估受到了关注，尤其是在久坐不动的人群中，如慢性阻塞性肺疾病（COPD）患者。本文旨在比较和讨论两种更常用于量化COPD患者日常生活中身体活动量的工具：主观方法（问卷、日记）和运动传感器（电子或机械方法）。总结了它们的特点，并在可行的情况下讨论了其有效性、可靠性和敏感性的证据。主观方法的实际价值主要在于提供患者对其日常生活活动表现和功能状态的看法。然而，在使用主观方法准确量化每日身体活动量时必须谨慎。使用运动传感器而非问卷可能会获得更准确的信息。选择哪种运动传感器用于量化日常生活中的身体活动应主要取决于其使用目的。
