ObjectiveTo observe the influence of medical exercise on rehabilitation of patients suffering from chronic obstructive pulmonary disease (COPD).Methods26 COPD patients who were organized in the form of training class practised medical exercise for three months. Respiratory function, exercise capacity and psychological health level were assessed respectively before and after exercise.ResultsValues of forced vital capacity(FVC), forced expiratory volume in one second (FEV1), FVC% , FEV1/ FVC and 6-minute walking distance (6MD) were significantly higher after medical exercise than before(P<0.01). Anxiety and depression scores also notably dropped after medical exercise than before(P<0.01).Conclusions Medical exercise can remarkably improve respiratory and moving capacity and decrease anxiety and depression of patients suffering from chronic obstructive pulmonary disease.
