| Objective: To explore the effects of three ball breathing trainers on lung rehabilitation training for chronic obstructive pulmonary disease (COPD) patients at stable phase. Methods: From April 2014 to August 2017, 78 cases of COPD at stable phase in our hospital were selected, and randomly divided into experimental group and control group with 39 cases in each group. Two groups were given routine treatment for 3 months. The experimental group was given three ball breathing trainers training additionally. Results: The effective rate of the experimental group and control group was 94.9% and 79.5% respectively (P<0.05). After treatment, the FEV1/FVC in the experimental group and the control group was significantly higher than before the treatment (P<0.05), and the FEV1/FVC in the experimental group was significantly higher than in the control group (P<0.05). The VO2max and maximum power in the experimental group after treatment were significantly higher than those in the control group before treatment (P<0.05), while there was no significant change in the control group before and after treatment (P>0.05). After treatment, the scores of SGRQ symptom, activity score, influence score and total score in the experimental group were significantly lower than those in the control group (P<0.05). Conclusion: The application of three ball breathing trainers in the COPD patients at stable phase can improve the lung function and exercise endurance, increase the therapeutic effect and improve the quality of life. |
