This study investigated whether adding step-feedback (step-FB) from a pedometer to pulmonary rehabilitation (PR) programs could increase the physical activity (PA) of low-activity patients with severe chronic obstructive pulmonary disease (COPD).
We included low-activity patients with severe COPD (step-FB group: 14 patients; control group: 17 patients) who underwent PR for the first time. The usual PR program for patients with severe COPD consisted of two 8-week sessions (PR session 1: PR1, PR session 2: PR2). The step-FB group was provided a program with step-FB added to PR2 (PR2+step-FB). Furthermore, all patients were evaluated at pre-intervention (baseline), PR1, and PR2. The primary outcome of this study was the number of daily steps (steps) and energy expenditure from activity (energy expenditure), as measured by a pedometer. The secondary outcomes were dyspnea and exercise tolerance.
In PR1, dyspnea, exercise tolerance, steps, and energy expenditure were significantly improved as compared to baseline, in both groups. During PR2, dyspnea and exercise tolerance were significantly improved as compared to PR1, in both groups. Steps and energy expenditure were significantly improved in the step-FB group, but not in the control group.
PR improved PA by improving physical function in severe COPD patients. Adding step-FB improved PA in severe COPD patients by presenting an activity goal for improving PA. Therefore, pedometer-based step-FB is a viable addition to PR and has the potential to improve PA continuously in these patients.
本研究调查了在肺康复（PR）项目中加入来自计步器的步数反馈（step-FB）是否能增加重度慢性阻塞性肺疾病（COPD）低活动量患者的身体活动（PA）。
我们纳入了首次接受PR的重度COPD低活动量患者（步数反馈组：14例患者；对照组：17例患者）。重度COPD患者的常规PR项目包括两个为期8周的疗程（PR疗程1：PR1，PR疗程2：PR2）。步数反馈组在PR2中加入了步数反馈（PR2 + 步数反馈）。此外，所有患者在干预前（基线）、PR1和PR2时均接受评估。本研究的主要结局是通过计步器测量的每日步数（步）和活动能量消耗（能量消耗）。次要结局是呼吸困难和运动耐量。
在PR1时，两组患者的呼吸困难、运动耐量、步数和能量消耗与基线相比均有显著改善。在PR2期间，两组患者的呼吸困难和运动耐量与PR1相比均有显著改善。步数反馈组的步数和能量消耗有显著改善，而对照组则没有。
PR通过改善重度COPD患者的身体功能提高了PA。加入步数反馈通过为改善PA提供活动目标，提高了重度COPD患者的PA。因此，基于计步器的步数反馈是PR的一个可行补充，并且有潜力在这些患者中持续改善PA。
