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 .
The effects of maintenance schedules following pulmonary rehabilitation in patients with chronic obstructive pulmonary disease: a randomised controlled trial
Objectives Pulmonary rehabilitation ( PR ) provides benefit for patients with chronic obstructive pulmonary disease ( COPD ) in terms of quality of life ( QoL ) and exercise capacity ; however , the effects diminish over time . Our aim was to evaluate a maintenance programme for patients who had completed PR . Setting Primary and secondary care PR programmes in Norfolk . Participants 148 patients with COPD who had completed at least 60 % of a st and ard PR programme were r and omised and data are available for 110 patients . Patients had greater than 20 pack year smoking history and less than 80 % predicted forced expiratory volume in 1 s but no other significant disease or recent respiratory tract infection . Interventions Patients were r and omised to receive a maintenance programme or st and ard care . The maintenance programme consisted of 2 h ( 1 h individually tailored exercise training and 1 h education programme ) every 3 months for 1 year . Primary and secondary outcome measures The Chronic Respiratory Question naire ( CRQ ) ( primary outcome ) , endurance shuttle walk test ( ESWT ) , EuroQol ( EQ5D ) , hospital anxiety and depression score ( HADS ) , body mass index ( BMI ) , body fat , activity levels ( overall score and activity diary ) and exacerbations were assessed before and after 12 months . Results There was no statistically significant difference between the groups for the change in CRQ dyspnoea score ( primary end point ) at 12 months which amounted to 0.19 ( −0.26 to 0.64 ) units or other domains of the CRQ . There was no difference in the ESWT duration ( −10.06 ( −191.16 to 171.03 ) seconds ) , BMI , body fat , EQ5D , MET-minutes , activity rating , HADS , exacerbations or admissions . Conclusions A maintenance programme of three monthly 2 h sessions does not improve outcomes in patients with COPD after 12 months . We do not recommend that our maintenance programme is adopted . Other methods of sustaining the benefits of PR are required . Trial registration number NCT00925171
