Study characteristics | ||
Methods | RCT, parallel group. Setting: Australia. Study duration: 3 months | |
Participants | 61 participants Intervention: n = 31, Control: n = 30 Age: not reported FEV1: not reported Inclusion criteria: COPD participants who participated in 6‐week outpatient PR Exclusion criteria: not reported |
|
Interventions | Intervention group: Components: exercise (aerobic and strength training). Exercise consisted of 30 minutes of lower limb endurance training (walking on a 20‐metre track, steps and pedals), upper limb exercises using free weights, and warm up and cool down exercises. Supervision: Participants in the maintenance group attended a weekly one‐hour exercise session at the community centre for twelve weeks. The session was supervised by a physiotherapist from the community health service and was based on the exercise training the subjects had been doing at the outpatient PR programme. Participants were encouraged to continue a home exercise program, maintain a home exercise diary and were invited to attend the monthly support group meetings. Control group: Usual care: They received ongoing medical care from their primary care provider. They were encouraged to continue a home exercise programme and maintain a home exercise diary. Participants were invited to attend the monthly “Huff and Puff” support group meetings held at the community centre. |
