Abstract

Purpose: This Stay Active after Rehabilitation (STAR) study examined the effects of a pedometer-based behavioral intervention for individuals with COPD during three weeks of inpatient pulmonary rehabilitation (PR) on their physical activity levels six weeks and six months after the PR, including steps (primary outcome), moderate-intensity physical activity, and sedentary time as well as patient quality of life, symptoms, and other psychological and clinical variables.

Patients and methods: Rehabilitation patients with COPD wore a triaxial accelerometer (ActiGraph wGT3X) for seven days two weeks before (T0) as well as six weeks (T3) and six months (T4) after PR. In addition to the three-week inpatient PR (control group, CG), the (randomly allocated) intervention group (IG) received a brief pedometer-based behavioral intervention with the application of the following behavior-change techniques: performing the behavior, individual goal-setting, self-monitoring, and feedback. The effects were analyzed using analysis of covariance with an intention-to-treat approach.

Results: A total of 327 patients (69% male, age: 58 years, FEV1 (%): 53.5, Six-Minute Walk Distance: 447.8 m) were randomly allocated to either the IG (n = 167) or CG (n = 160). Although both groups increased their daily steps after PR (IG: MT3-T0 = 1152, CG: MT3-T0 = 745; IG: MT4-T0 = 795, CG: MT4-T0 = 300), the slightly higher increases in daily steps in the IG compared to the CG at T3 (Δ388 steps, d = 0.16) and T4 (Δ458 steps, d = 0.15) were not statistically significant (p > 0.05 for all). Patients in both groups showed moderate to high pre-post-changes in terms of secondary outcomes, but no advantage favoring the IG was found.

Conclusions: The results show that adding a pedometer-based behavioral intervention to standard German three-week inpatient PR for COPD patients did not result in more physical activity in terms of steps and moderate-intensity physical activity or less sedentary time. However, both groups (IG and CG) showed remarkably enhanced physical activity levels six weeks and six months after PR as well as improvements in the other secondary outcomes (e.g., quality of life).
