Abstract: Objective To explore the effect of unsupported arm exercise (UAE) on dyspnea, exercise endurance of upper limbs and quality of life in patients with chronic obstructive pulmonary disease (COPD). Methods From May to October, 2014, totally 70 patients with COPD were recruited and were randomly assigned to control group and intervention group. Both groups received routine care, and the intervention group performed UAE for six weeks additionally. The COPD Assessment Test (CAT), baseline dyspnoea index (BDI) and six-minute Pegbord and Ring Test (6PBRT) were recorded. Results The scores of CAT and BDI, and the number of turns in six minutes were better in the intervention group than in the control group (P<0.05). Conclusion UAE can increase the exercise endurance of upper limbs, relieve the dyspnea, and improve the quality of life in patients with COPD.
