提高运动能力是慢性阻塞性肺疾病的首要目标。运动量的下降会导致体力活动和与健康相关的生活质量(HRQOL)的降低。自我管理干预可以教会患者管理疾病的技能和行为。以技术为中介的干预措施有可能为疾病自我管理提供容易获得的支持。我们评估了基于网络的自我管理干预的有效性，重点是促进身体活动，对COPD患者的运动能力进行研究。这项为期6个月的随机对照试验(NCT02099799)在美国的两个地点招募了153名COPD患者(VABoston，n=108；VABirmingham，n=45)。参与者被分配到基于网络的自我管理干预(通过个性化、渐进的步数目标、反馈、与COPD相关的在线教育和通过在线社区的社会支持促进体力活动)或常规护理(1：1)。主要结果是运动能力(6min步行距离(6MWD))。次要结果包括体力活动(每天步行)、HRQOL(圣乔治呼吸问卷总分)、呼吸困难、COPD相关知识和社会支持。步数目标的变化反映了干预参与度。受试者的平均年龄为69岁(SD=7)，1 S预测的平均用力呼气量为61%(SD=21%)。6MWD的变化在不同组之间没有差异。与常规护理组相比，干预组患者的平均每日步数增加了1312步(p
Improving exercise capacity is a primary objective in COPD. Declines in exercise capacity result in reduced physical activity and health-related quality of life (HRQoL). Self-management interventions can teach patients skills and behaviours to manage their disease. Technology-mediated interventions have the potential to provide easily accessible support for disease self-management. We evaluated the effectiveness of a web-based self-management intervention, focused on physical activity promotion, on exercise capacity in COPD. This 6-month randomised controlled trial (NCT02099799) enrolled 153 persons with COPD at two US sites (VABoston, n=108; VABirmingham, n=45). Participants were allocated (1:1) to the web-based self-management intervention (physical activity promotion through personalised, progressive step-count goals, feedback, online COPD-related education and social support via an online community) or usual care. The primary outcome was exercise capacity (6-min walk distance (6 MWD)). Secondary outcomes included physical activity (daily steps per day), HRQoL (St. George's Respiratory Questionnaire Total Score), dyspnoea, COPD-related knowledge and social support. Change in step-count goals reflected intervention engagement. Participants' mean age was 69 (SD=7), and mean forced expiratory volume in 1 s % predicted was 61% (SD=21%). Change in 6MWD did not differ between groups. Intervention participants improved their mean daily step counts by 1312 more than those in the usual care group (p
