Objective To evaluate the effect of respiratory rehabilitation on the life quality of patients with stable chronic ob-structive pulmonary disease (COPD).Methods Sixty patients with acute episode of COPD admitted into the hospital for treatment were randomly divided into 2 groups:the experimental group and the control group,each consisting of 30 cases.When the medical con-ditions became stable,the patients of the experimental group were given respiratory rehabilitation in addition to routine treatment.When discharged from hospital and 3 months after discharge,the patients of the 2 groups received CAT questionnaire survey and FEV1 (%) pulmonary function test.Results Significant differences in the fractions of CAT scores could be seen,when scores detected at the dis-charge and 3 months after discharge were compared between the 2 groups(P <0.01 ).Significant differences in the values of FEV1 (%)could also be seen,when scores detected at the discharge and 3 months after discharge were compared between the 2 groups(P <0.01).Conclusion Through comparisons of the fractions of CAT scores and FEV1 (%)scores between the 2 groups,it was shown that conventional therapy coupled with respiratory rehabilitation could significantly improve the pulmonary function of the patients with COPD.
