Twenty elderly patients with COPD (Age 76 ± 7 years; FEV1 56.6 ± 18.7 % pred) were evaluated using this activity monitor for 3 consecutive days before and after PR. The home-based PR program included a chair-walking exercise, lower muscle training, stretch of body trunk, respiratory muscle training and education of self management. Pulmonary function, exercise capacity (6-min walking distance; 6MWD), quadriceps muscle force (QF), and health-related QOL (CRQ) were evaluated before and after PR.Results: Active-walking time increased (pre PR: 27 ± 23 vs. post PR: 52 ± 31 min/day) and lying time decreased (pre PR: 53± 18vs. post PR: 38 ± 18 min/day) significanlty after PR. Frequency of standing increased (pre PR: 80 ± 42 vs post PR: 117 ± 63 times/day) significantly after PR. The degree of improvement of active-walking time after PR was correlated with 6MWD and QF.Conclusions: These data suggested that home-based PR consisting of a chair-walking exercise and lower muscle training was effective in improving active-walking time in elderly patients with COPD.
