[Purpose] This study was designed to determine the effect of a respiration rehabilitation program on daily activities, satisfaction with leisure, and quality of sleep of patients with chronic obstructive pulmonary disease. [Subjects and Methods] The program was conducted three times a week for 12 weeks (a total of 36 times) with 20 patients aged between 50 and 70 years old. The Frenchay Activity Index was used to determine the instrumental activities of daily living before and after the intervention. The Korean scale of satisfaction with leisure was employed to determine the satisfaction with leisure, and the Korean version of the Pittsburgh Sleep Quality Index was used to measure the quality of sleep. [Results] The total score of all three instruments (instrumental activities of daily living (IADL), satisfaction with leisure, and quality of sleep) improved significantly after the intervention. [Conclusion] In conclusion, the scores of all three instruments (IADL, satisfaction with leisure, and quality of sleep) improved significantly after the intervention, indicating that the respiration rehabilitation program was effective at improving the overall quality of life for patients with chronic obstructive pulmonary disease.
