Interventions that included ET and PA counseling during PR were effective strategies to improve PA in COPD
BACKGROUND Physical inactivity is associated with poor outcomes in COPD , and as a result , interventions to improve physical activity ( PA ) are a current research focus .
However , many trials have been small and inconclusive .
OBJECTIVE The aim of this systematic review and meta- analysis was to study the effects of r and omized controlled trials ( RCTs ) targeting PA in COPD .
Internet-based dyspnea self-management support for patients with chronic obstructive pulmonary disease.
CONTEXT People with chronic obstructive pulmonary disease experience dyspnea  with activities despite optimal medical management . OBJECTIVES The purpose of this study was to test the efficacy of two 12-month dyspnea self-management programs ( DSMPs ) , Internet-based ( eDSMP ) and face-to-face ( fDSMP ) , compared with a general health education ( GHE ) control on the primary outcome of dyspnea with activities . METHODS Participants with chronic obstructive pulmonary disease were r and omized to eDSMP ( n=43 ) , fDSMP ( n=41 ) , or GHE ( n=41 ) . The content of the DSMPs were similar and focused on education , skills training , and coaching on dyspnea self-management strategies , including exercise , and only differed in the delivery mode . Dyspnea with activities was measured with the Chronic Respiratory Question naire at three , six , and 12 months . Secondary outcomes included exercise behavior and performance , health-related quality of life , self-efficacy for dyspnea management , and perception of support for exercise . The study was registered at Clinical trials.gov ( NCT00461162 ) . RESULTS There were no differences in dyspnea with activities across groups over 12 months ( P=0.48 ) . With the exception of arm endurance ( P=0.04 ) , exercise behavior , performance , and health-related quality of life did not differ across groups ( P>0.05 ) . Self-efficacy for managing dyspnea improved for the DSMPs compared with GHE ( P=0.06 ) . DSMP participants perceived high levels of support for initiating and maintaining an exercise program . CONCLUSION The DSMPs did not significantly reduce dyspnea with activities compared with attention control . However , the high participant satisfaction with the DSMPs combined with positive changes in other outcomes , including self-efficacy for managing dyspnea and exercise behavior , highlight the need for additional testing of individually tailored technology-enabled interventions to optimize patient engagement and improve clinical ly relevant outcomes
