Objective: The objective of this study was to assess the effectiveness of conventional PR versus web-based PR with respect to changes in PA. Methods: Patients with COPD were randomized to either conventional PR classes (n=51) or a web-based PR program (n=52) for 7 weeks in a feasibility study. Accelerometers (Sensewear) were worn before and after the intervention, and PA was measured as steps per day and mean bouts of moderate activity for ≥2, ≥5, ≥10, and ≥20 minutes. Measures were derived for patients with ≥8 hours of data per day for ≥4 days, using the R package for statistical analysis. Variables were explored to examine their relationships with bouts of activity. Results: Baseline characteristics did not differ significantly between groups. Complete PA data were available for the groups receiving web-based (n=20) and conventional (n=34) PR interventions. The web-based PR group demonstrated a nonsignificant increase in the number of steps per day, which mainly comprised short bouts of moderate to vigorous intensity PA when compared to the conventional PR group (P=.20). The conventional PR group demonstrated increased 20-minute bouts of PA by 49.1{\%}, although this was not significant (P=.07). At baseline, age (r=--0.21, P=.04), BMI (r=--0.311, P=.004), and FEV1 (forced expiratory volume in 1 second; {\%} predicted; r=--0.248, P=.048) were significantly correlated with 10-minute bouts of PA; however, this was not observed post intervention. Conclusions: The analysis revealed a nonsignificant difference in the pattern of PA between groups receiving conventional vs web-based PR---the former being associated with an increase in 20-minute bouts, while the latter having demonstrated an increase in the number of steps per day. There appears to be a differing response emerging between the two interventions.
