ABSTRACT

Objective To explore the effect of self-designed breathing exercise on the six-minute walking distance and quality of life in stable patients with chronic obstructive pulmonary disease (COPD).Methods 60 patients with COPD were collected and divided into respiratory exercise group,positive control group and negative control group according to the random number table.Three groups of patients were treated with regular medication according to the GOLD (2016) guidelines,and accepted scheduled healthy knowledge education.Positive control group plus the 12-week aerobic exercise training (50％-80％ of the intensity of HRmax,30 minutes a day,three times a week).The respiratory exercise group began to carry out self-designed respiratory exercise training after discharge,which ensured that the patients would receive regular breathing exercise training three times a week and continue for last without interruption.On the day of enrollment,the evaluation will be conducted 3 months after the training.The evaluation indexes were six minutes walking distance (6WMD) and scores of COPD Clinical Questionnaire (CCQ).Results In the respiratory exercise group and the positive control group,both 6WMD and CCQ were significantly improved compared with that before rehabilitation (P ＜0.01).Compared with the negative control group,the 6WMD and CCQ of the respiratory exercise group and the positive control group were both significantly improved (P ＜0.01).But there was was no significant statistically difference between the respiratory exercise group and the positive control group (P ＞ 0.05),and the improvement degree of 6WMD and CCQ in the two groups was similar.Conclusions Self-designed breathing exercises can improve the walking distance and quality of life of patients with stable chronic obstructive pulmonary disease and achieve the same effect as exercise training.
