METHODS: Systematic review, meta-analysis and meta-regression of randomised controlled trials.
METHODS: People with stable COPD.
METHODS: Trials were included if they applied ≥ 4 weeks of a whole-body ETP and reported outcome data immediately following program completion and 12 months after initial program completion. The control group received usual care that did not include a formal exercise training component.
METHODS: Exercise tolerance, health-related quality of life and dyspnoea during activities of daily living.
METHODS: EMBASE, PEDro, PubMed and the Cochrane Library.
RESULTS: Nineteen randomised trials with 2,103 participants were found, of which 12 had a sufficiently similar design to be meta-analysed. At 12 months after ETP completion, compared with the control group, the experimental group demonstrated better exercise tolerance (SMD 0.48, 95% CI 0.19 to 0.77) and quality of life (SMD 0.22, 95% CI 0.03 to 0.41) with no clear effect on dyspnoea. Meta-regression using data from all 19 trials demonstrated that the magnitude of between-group differences at the 12-month follow-up was moderated by: behaviour change being a core aim of the strategies implemented following completion of the ETP; the experimental group receiving more behaviour change techniques during the program; and the magnitude of between-group change achieved from the program.
CONCLUSIONS: At 12 months after completion of an ETP of ≥ 4 weeks, small gains were maintained in exercise tolerance and health-related quality of life. Applying behaviour change techniques with a clear focus on participants integrating exercise into daily life beyond initial program completion is important to maintain training-related gains.
BACKGROUND: CRD42020193833.
方法:系统评价,随机对照试验的荟萃分析和荟萃回归。
方法:COPD稳定期患者。
方法:如果应用≥4周的全身ETP,并在项目完成后和初始项目完成后12个月立即报告结果数据,则纳入试验。对照组接受常规护理,但不包括正式的运动训练。
方法:运动耐量,日常生活活动中与健康相关的生活质量和呼吸困难。
方法:EMBASE,PEDro,PubMed和Cochrane图书馆。
结果:发现了19项随机试验,共有2,103名参与者,其中12个具有足够相似的设计,可以进行荟萃分析。ETP完成后12个月,与对照组相比,实验组表现出更好的运动耐量(SMD0.48,95%CI0.19~0.77)和生活质量(SMD0.22,95%CI0.03~0.41),对呼吸困难无明显影响.使用来自所有19项试验的数据进行的荟萃回归表明,在12个月的随访中,组间差异的幅度受到以下因素的调节:行为改变是ETP完成后实施策略的核心目标;实验组在程序中接受更多的行为改变技术;以及从程序中获得的组间变化的幅度。
结论:在完成≥4周的ETP后12个月,在运动耐量和与健康相关的生活质量方面,我们保持了微小的进步.应用行为改变技术,明确关注参与者将锻炼纳入日常生活,而不是最初的计划完成,这对于保持与培训相关的收益很重要。
