Pedometer Intervention to Improve Daily Physical Activity and Quality of Life in Patients With Stable COPD

SESSION TITLE: Pulmonary Rehabilitation SESSION TYPE: Original Investigation Slide PRESENTED ON: Monday, October 30, 2017 at 07:30 AM - 08:30 AM PURPOSE: Since daily physical activity (DPA) is a key factor to manage patients with stable COPD, interventions to induce behavioral change are attracting special attention, especially, in relation to pedometer. To confirm the effects of pedometer intervention on the time course of DPA, and to examine whether COPD Assessment Test (CAT) affects the DPA time course or not. METHODS: Male patients with stable COPD (n = 27, age ; 73.7 ± 6.7, %FEV1 ; 69.5 ± 21.0, data expressed as Mean ± SD) who were regularly visiting to our out-patient clinics were retrospectively analyzed. Following the initial assessment and instructions, at each visit, CAT was scored by the patients, and medical professional stuffs which were composed of a physician, a physical therapist, and nurses advised the patients to put pedometer on and to record the daily counts every day. Further, the staffs and the patients together talked about the pedometer and/or the records as it was like daily conversation with the staffs’ educational minds. RESULTS: DPA significantly increased from the baseline (4796 ± 2484, steps/day) to those at 3 month (6274 ± 2984, steps/day, p < 0.01), and it was well maintained over 1 year (5764 ± 3422, steps/day, p < 0.05). CAT scores significantly decreased from the baseline (11.1 ± 8.1, points) to those at 3 month (9.0 ± 7.6, points, p < 0.05). Two subgroups which were separated by CAT < 10 (n=14) or CAT > 10 (n=13) showed similar and significant increase in DPA at 3 month (p < 0.01). However, DPA at 1 year tended to be better maintained in the subgroup CAT < 10 (p < 0.05). CONCLUSIONS: The pedometer education was confirmed to maintain DPA at least for 1 year. Impaired quality of life (QOL) possibly attenuated these favorable effects. CLINICAL IMPLICATIONS: Pedometer is useful intervention for physical activity, which may be affected by QOL.
