目得：评估3种不同“剂量”的有监督运动的呼吸困难自我管理项目后呼吸困难、运动能力、健康相关生活质量和卫生资源利用的长期结局差异。患者和方法：在一项前瞻性、随机、单盲、1年试验中，稳定的慢性阻塞性肺疾病患者（N = 103;年龄66 +/- 8，女性57; FEV 1 44.8% +/- 14%预测值）被随机分配到：（1）呼吸困难自我管理计划（DM）;（2）DM +4次监督锻炼（DM暴露）;或（3）DM +24次监督锻炼（DM训练）。呼吸困难自我管理计划包括个性化教育和呼吸困难自我管理策略的演示，个性化的家庭步行处方，以及每两周一次的护士电话。结果在基线和每2个月为1 year.RESULTS：DM训练组有显着更大的改善呼吸困难在增量跑步机测试和运动性能的增量和耐力跑步机测试在6个月和12个月相比，其他2组。随着时间的推移，所有组的呼吸困难与日常生活活动和自我报告的身体功能均显著改善。监督运动和改善呼吸困难目前在2个月之间的剂量反应关系是不持续超过year.CONCLUSION：与以前的研究结果一致，从肺康复计划的评估研究，更大数量的监督运动训练课程改善实验室呼吸困难和性能比其他两个剂量的运动。从长期来看，所有3组呼吸困难与日常生活活动和身体功能的改善相似。
PURPOSE: To evaluate the differences in the long-term outcomes of dyspnea, exercise performance, health-related quality of life, and health resource utilization following a dyspnea self-management program with 3 different "doses" of supervised exercise.PATIENTS AND METHODS: In a prospective, randomized, single-blind, 1-year trial, patients with stable chronic obstructive pulmonary disease (N = 103; age 66 +/- 8, females 57; FEV1 44.8% +/- 14% predicted) were randomly assigned to either: (1) Dyspnea self-management program (DM); (2) DM plus 4 supervised exercise sessions (DM-exposure); or (3) DM plus 24 supervised exercise sessions (DM-training). The dyspnea self-management program included individualized education and demonstration of dyspnea self-management strategies, an individualized home walking prescription, and biweekly nurse telephone calls. Outcomes were measured at baseline and every 2 months for 1 year.RESULTS: The DM-training group had significantly greater improvements in dyspnea during incremental treadmill test and in exercise performance on the incremental and endurance treadmill tests at 6 and 12 months compared with the other 2 groups. Dyspnea with activities of daily living and self-reported physical functioning significantly improved for all groups over time. The dose-response relationship between supervised exercise and improvement in dyspnea present at 2 months was not sustained over the year.CONCLUSION: Consistent with previous findings from evaluation studies of pulmonary rehabilitation programs, the greater number of supervised exercise training sessions improved laboratory dyspnea and performance more than the other two doses of exercise. In the long term, the improvement in dyspnea with activities of daily living and physical functioning was similar for all 3 groups.
