The elastic tape (ET) is a novel intervention that acutely improves exercise capacity in laboratory tests; however, its effect on a patient's daily life remains unknown. This randomized controlled trial evaluated the effects of ET on daily life physical activity (DLPA), dyspnea symptoms, health status, and health-related quality of life (HRQoL) in individuals with COPD.
Fifty males with moderate to very severe COPD were randomly assigned to an intervention group (ETG, n = 25), receiving ET on the chest wall and abdomen, or a control group (CG, n = 25). The intervention was for 14 days. DLPA (accelerometry; steps per day, and sedentary time), dyspnea symptoms (transition dyspnea index, TDI; and modified Medical Research Council, mMRC), health status (COPD assessment test, CAT), and health-related quality of life (HRQoL, CRQ) were evaluated at baseline and on Day 21 after the intervention.
No change in the DLPA was observed in between-group comparison. CG presented a reduction in step counts after 21days (-707,p <0.05) while ETG. maintained (-114,p > 0.94). However, ET reduced dyspnea symptoms in all TDI domains (functional, task, and effort) and on the mMRC scale after 14 days compared with CG (p < 0.01). Also, the ETG improved CAT score compared to the CG, reaching minimal clinical important difference (MCID) (-4.4 score, p <0.01). The ETG also improved in most CRQ domains reaching MCID after 21 days.
ET does not modify DLPA but reduces dyspnea and improves health status and HRQoL in nonobese males with moderate to very severe COPD in the short term. This novel and low-cost intervention improves COPD symptoms.
弹性带（ET）是一种新的干预措施，可在实验室测试中急性改善运动能力；然而，其对患者日常生活的影响尚不清楚。这项随机对照试验评估了 ET 对慢性阻塞性肺疾病（COPD）患者日常生活体力活动（DLPA）、呼吸困难症状、健康状况和健康相关生活质量（HRQoL）的影响。
50 名男性中至重度 COPD 患者被随机分配到干预组（ETG，n=25），在胸壁和腹部接受 ET，或对照组（CG，n=25）。干预时间为 14 天。使用加速度计评估 DLPA（每日步数和久坐时间）、呼吸困难症状（过渡性呼吸困难指数，TDI；和改良的医学研究委员会，mMRC）、健康状况（COPD 评估测试，CAT）和健康相关生活质量（HRQoL，CRQ），在干预前和干预后第 21 天进行评估。
组间比较未观察到 DLPA 变化。CG 在 21 天后的步数减少（-707，p<0.05），而 ETG 则维持（-114，p>0.94）。然而，与 CG 相比，ET 在 14 天后在所有 TDI 领域（功能、任务和努力）和 mMRC 量表上减轻了呼吸困难症状（p<0.01）。此外，与 CG 相比，ETG 改善了 CAT 评分，达到了最小临床重要差异（MCID）（-4.4 分，p<0.01）。ETG 还在 21 天后改善了大多数 CRQ 领域，达到了 MCID。
ET 不会改变 DLPA，但在短期内可减轻非肥胖中至重度 COPD 男性的呼吸困难，并改善健康状况和 HRQoL。这种新的、低成本的干预措施可改善 COPD 症状。
