Interventions with a Clear Focus on Achieving Behaviour Change Are Important for Maintaining Training-Related Gains in People with Chronic Obstructive Pulmonary Disease: a Systematic Review
Journal of physiotherapy(2024)
摘要
Questions In people with chronic obstructive pulmonary disease (COPD) who complete an exercise training program (ETP) offered at a sufficient dose to result in training-related gains, to what extent are these gains maintained 12 months after program completion? Do variables such as the application of behaviour change techniques moderate the maintenance of these training-related gains? Design Systematic review, meta-analysis and meta-regression of randomised controlled trials. Participants People with stable COPD. Intervention 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. Outcome measures Exercise tolerance, health-related quality of life and dyspnoea during activities of daily living. Data sources 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. Conclusion 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.
