BACKGROUND: Many trials supporting the benefits of pulmonary rehabilitation (PR) have used specialist exercise equipment, such as treadmills and cycle ergometers. However, access to specialist equipment may not be feasible in some settings. There is growing interest in delivering PR programmes with minimal, low-cost equipment, but uncertainty remains regarding their efficacy compared with programmes using specialist equipment. METHODS: Using propensity score matching, 318 consecutive patients with COPD undergoing supervised PR using minimal equipment (PR-min) were compared 1:1 with a control group of 318 patients with COPD who underwent supervised PR using specialist equipment (PR-gym). A non-inferiority analysis was performed for the primary outcome (incremental shuttle walk (ISW)) and secondary outcomes (Chronic Respiratory Disease Questionnaire (CRQ)-domain and total scores). RESULTS: Similar improvements in ISW and CRQ-domains were observed in PR-min and PR-gym groups (mean difference ISW: 3 m (95% CI -16 to 9); CRQ-total: 0.9 (95% CI -2.7 to 4.5)). The 95% CI between group differences for ISW and CRQ-total did not cross the predefined non-inferiority margins. However, completion rates were lower in PR-min compared with PR-gym (64% vs 73%; p=0.014). CONCLUSIONS: In patients with COPD, PR delivered using minimal equipment produces clinically significant benefits in exercise capacity and health-related quality of life that are non-inferior to rehabilitation delivered using specialist equipment. This study provides support for the provision of PR using minimal exercise equipment, particularly in areas where access to specialist exercise equipment is limited.
背景:许多支持肺康复(PR)益处的试验都使用了专业的运动设备,如跑步机和脚踏车测力计。然而,在某些环境中,获得专业设备可能不可行。使用最少、低成本设备提供 PR 计划的兴趣日益浓厚,但与使用专业设备的计划相比,其疗效仍存在不确定性。 方法:使用倾向评分匹配,将 318 例连续 COPD 患者接受最小设备(PR-min)监督下的 PR 治疗与 318 例接受专业设备(PR-gym)监督下的 PR 治疗的对照组进行 1:1 比较。对主要结局(递增穿梭步行距离(ISW))和次要结局(慢性呼吸道疾病问卷(CRQ)-域和总分)进行非劣效性分析。 结果:PR-min 和 PR-gym 组的 ISW 和 CRQ 域均观察到相似的改善(ISW 平均差异:3 米(95%CI -16 至 9);CRQ 总分:0.9(95%CI -2.7 至 4.5))。ISW 和 CRQ 总分的组间差异 95%CI 未跨越预设的非劣效性边界。然而,PR-min 的完成率低于 PR-gym(64% vs 73%;p=0.014)。 结论:在 COPD 患者中,使用最小设备提供的 PR 可显著改善运动能力和健康相关生活质量,其疗效与使用专业设备提供的康复相当。本研究为使用最小运动设备提供 PR 提供了支持,特别是在专业运动设备获取受限的地区。
