In patients with chronic obstructive pulmonary disease (COPD), energy expenditure (EE) assessment during the performance of daily activities is not yet studied in depth. The aim of this study was to determine which daily activities are more demanding to patients with COPD and to compare the accuracy of EE estimation given by the pedometer Digiwalker SW701 (DW) and the multisensor SenseWear Armband (SAB).
Thirty-six patients with COPD (20 men; FEV1 48 ± 15%predicted; BMI 25.7 ± 8 kg/m(2)) were submitted to a modified version of the Glittre ADL-test, which included five activities performed for 1 min each: walking on the level, walking on the level carrying a backpack, walking up/downstairs, rising/sitting in chairs and moving objects in and out of a shelf. During the protocol subjects wore both devices concomitantly, and indirect calorimetry (IC) was simultaneously performed as the criterion method to assess EE.
The most demanding daily activity for individuals with COPD was walking up/downstairs (4.9 ± 1.7 kcal versus 3.7 ± 1.4 to 4.2 ± 1.8 kcal for the other tasks; p < 0.05). EE estimation by the SAB did not show difference in comparison to IC for the sum of the five activities (SAB = 22.7 ± 7 kcal versus IC = 21 ± 8 kcal; p > 0.05), although overestimation was found in activities involving walking. DW showed significant EE underestimation in the sum of the activities (9.6 ± 4.3 kcal; p < 0.05 versus IC) and for each activity.
Walking up/downstairs was the most energy-demanding daily activity for patients with COPD. Furthermore, during daily activities, the multisensor showed adequate overall estimation of energy expenditure, as opposed to the pedometer.
在慢性阻塞性肺疾病（COPD）患者中，对日常活动期间能量消耗（EE）的评估尚未进行深入研究。本研究的目的是确定哪些日常活动对 COPD 患者要求更高，并比较计步器 Digiwalker SW701（DW）和多传感器 SenseWear 臂带（SAB）提供的 EE 估计的准确性。
36 名 COPD 患者（20 名男性；FEV1 48 ± 15%预计值；BMI 25.7 ± 8 kg/m2）接受了改良的 Glittre ADL 测试，该测试包括 5 项各持续 1 分钟的活动：在平地上行走、在平地上携带背包行走、上下楼梯、在椅子上起身/坐下和在架子上进出物品。在该方案中，患者同时佩戴两种设备，同时进行间接测热法（IC）以评估 EE。
对 COPD 患者来说，最具挑战性的日常活动是上下楼梯（4.9 ± 1.7 kcal 与其他任务的 3.7 ± 1.4 至 4.2 ± 1.8 kcal 相比；p < 0.05）。SAB 对五项活动总和的 EE 估计与 IC 无差异（SAB = 22.7 ± 7 kcal 与 IC = 21 ± 8 kcal；p > 0.05），尽管在涉及步行的活动中存在高估。DW 在活动总和（9.6 ± 4.3 kcal；p < 0.05 与 IC）和每项活动中均显示出明显的 EE 低估。
上下楼梯是 COPD 患者要求最高的日常活动。此外，在日常活动中，多传感器对能量消耗的整体估计是适当的，而计步器则不然。
