Pulmonary patients attending outpatient rehabilitation experience an enhanced ability for physical activity. The current study assessed and characterized domestic physical activity levels of new and maintenance patients to 1) compare physical activity levels of pulmonary patients on rehabilitation and non-rehabilitation days, 2) to identify factors that may contribute to low physical activity levels and 3) to compare step count levels between 2 activity monitors.Eighteen patients (age, 66.2 ± 8.8 y; FEV1, 52.1 ± 11.8%) participating in pulmonary rehabilitation wore an accelerometer and pedometer for 7 consecutive days. Patients new to pulmonary rehabilitation and maintenance patients participated in the study. Upon returning the monitors, patients returned a log sheet with the times monitors were put on and taken off each morning and night.The participants who completed the one week assessment had an average step count of 3,800 ± 1,651 steps/day, with a significant difference (p < .05) between rehabilitation days (5,468 ± 2,810 steps/day) and non-rehabilitation days (2,874 ± 1,490 steps/day). The number of minutes/day spent in moderate walking activities was also significant (p < .05) between rehabilitation (10.9 ± 16.0 minutes/day) and non-rehabilitation days (3.1 ± 5.8 minutes/day). Male waist circumference and occupational status were significantly correlated with low physical activity levels. The pedometer and accelerometer step count values were not significantly different from each other.Patients participating in pulmonary rehabilitation have significantly different activity levels between rehabilitation and non-rehabilitation days. To increase activity benefits, patients with COPD should increase activity levels on rehabilitation and non-rehabilitation days. Special consideration should be taken to help patients increase physical activity levels on non-rehabilitation days.(key words: chronic obstructive pulmonary disease, pedometer, accelerometer, pulmonary rehabilitation.
