Background: Pulmonary rehabilitation is widely recommended for the treatment of chronic obstructive pulmonary disease. Objective: To evaluate the efficacy of pulmonary rehabilitation in improving exercise capacity, respiratory muscle strength and quality of life of chronic obstructive pulmonary disease patients. Method: This was an open, non-randomized clinical trial involving 27 clinically stable ex-smokers with chronic obstructive pulmonary disease who were enrolled in a pulmonary rehabilitation program. All were evaluated before and after pulmonary rehabilitation. Results: Mean age was 65 ± 5 years, mean body mass index was 25 ± 4 kg/m2, mean forced expiratory volume in one second was 55 ± 25% of predicted, mean ratio between forced expiratory volume in one second and forced vital capacity was 50 ± 12%, and mean arterial oxygen tension was 70 ± 7 mmHg. Comparison of pre- and post-pulmonary rehabilitation values revealed improvement in the distance walked in the 6-minute walk test (513 ± 99 m vs. 570 ± 104 m), maximum upper limb load (2 ± 1 kg vs. 3 ± 1 kg) and maximal inspiratory pressure (-89 ± 23 cmH2O vs. -102 ± 23 cmH2O), as well as in the activity domain, impact domain and total score on the Saint George's Respiratory Questionnaire. Conclusion: Pulmonary rehabilitation, when performed with care and with a focus on physical training, is efficacious in increasing not only the distance walked in the 6-minute walk test but maximum upper limb load, maximal inspiratory pressure and quality of life as well.

Introduction: The patient with COPD has his global physical activity decreased due to a progressive worsening of the lung function resultant from any kind of physical effort he may perform. Pulmonary rehabilitation (PR) is used in the United States and Europe as an alternative therapy in COPD treatment. Objective: To evaluate the effectiveness of PR as an ancillary treatment for COPD. Patients and methods: 30 patients prospectively submitted to the PR program developed in six weeks with three weekly sessions. Evaluation included clinical history and complete physical examination, the six-minute walking distance test, maximum workload test for upper limbs, maximum load test for lower limbs, a questionnaire of effort perception, spirometry and analysis of blood gases. Results: Concerning spirometry and analysis of blood gases, pre and post PR program, no statistically significant change was observed (p > 0.05). Pre and post PR program, statistically significant values (p < 0.05) were observed in the decrease in effort perception and increase in functional physical capacity, maximum workload test for upper limbs and incremental test for lower limbs used to determine the maximum workload. Conclusions: The authors concluded that, in the group studied, the PR program increased the patients' physical capacity and maximum workload for upper limbs whereas no changes were observed in the data regarding spirometry and analysis of blood gases.
