Abstract
dc.description.abstract
Physical inactivity is a cardinal feature of chronic obstructive pulmonary disease (COPD),
and is associated with increased morbidity and mortality. Pedometers, which have been used in healthy
populations, might also increase physical activity in patients with COPD.
COPD patients taking part in a 3-month individualised programme to promote an increase in their
daily physical activity were randomised to either a standard programme of physical activity encouragement
alone, or a pedometer-based programme. Assessments were performed by investigators blinded to
treatment allocation. Change in average 1-week daily step count, 6-min walking distance (6MWD),
modified Medical Research Council scale, St George’s respiratory questionnaire (SGRQ) and COPD
assessment test (CAT) were compared between groups.
102 patients were recruited, of whom 97 completed the programme (pedometer group: n=50; control
group: n=47); 60.8% were male with a mean±SD age of 68.7±8.5 years, and forced expiratory volume in 1 s
(FEV1) 66.1±19.4% and FEV1/forced vital capacity 55.2±9.5%. Both groups had comparable characteristics
at baseline. The pedometer group had significantly greater improvements in: physical activity 3080±3254
steps·day−1 versus 138.3±1950 steps·day−1 (p<0.001); SGRQ −8.8±12.2 versus −3.8±10.9 ( p=0.01); CAT
score −3.5±5.5 versus −0.6±6.6 (p=0.001); and 6MWD 12.4±34.6 versus −0.7±24.4m (p=0.02) than
patients receiving activity encouragement only.
A simple physical activity enhancement programme using pedometers can effectively improve physical
activity level and quality of life in COPD patients
