However, patients with stable disease may drop out of such programs if they are not modified to the individual's exercise tolerance level, or if they are not easy to perform in the home. Little is known about the effectiveness of web-based home breathing programs for dyspnea. The purpose of this study was to evaluate the effectiveness of an online breathing program which included an animated diagram and video-guided instruction on pulmonary function, exercise capacity, and health-related quality of life in patients with COPD. Methods: Sixty patients with stable COPD were randomized 1:1 to an experimental group (n = 30) or a control group (n = 30). Subjects in the experimental group trained for four months using an online program which included an animated diagram and video-guided instruction while the control group received conventional patient education on discharge from hospital. Forced expiratory volume, forced expiratory volume in one second (FEV1)/forced vital capacity (%), peak expiratory volume, six-minute walking distance test, and responses to the St George's Respiratory Questionnaire were assessed before and after the intervention. Results: Patients in the two groups were well matched for demographic and clinical characteristics at baseline. All outcome measures showed significant improvement in the experimental group but not in the control group. Conclusion: The online training program resulted in improved pulmonary function, exercise capacity, and health status. Therefore, it is strongly recommended that patients with stable COPD be trained with such programs.
