目的 比较两种不同强度的上下肢训练对老年COPD患者的疗效评价.方法 采用随机分组的方法将73例稳定期老年COPD患者分为2组,分别接受2种不同强度的上下肢训练,为期12周.比较康复前后及2组患者的肺功能、6 min步行距离、基线呼吸困难指数评分、体重指数的差异及2组的脱漏率.结果 经过12周的两种不同强度的上下肢训练干预,高强度肺康复组在6 min步行距离、呼吸困难程度评分较低强度肺康复组明显改善(P＜0.01);但脱漏率明显增高(P＜0.05).两组的肺功能、体重指数在康复前后无明显改变.结论 对于老年稳定期COPD患者两种不同强度的上下肢训练均能改善其呼吸困难症状及运动耐力;高强度肺康复组较低强度肺康复组疗效明显;但脱漏率明显增高;而肺功能、体重指数两组在康复前后无明显改善.“,”Objective To compare the effect of different intensity of upper and lower extremity exercise with elderly COPD patients of pulmonary rehabilitation. Methods 73 stable elderly COPD patients were divided into two groups randomly. After a baseline multi-dimensional assessment, patients underwent a 12-week rehabilitation cycle including training higher and lower exercise intensity of the upper and lower extremities, The pulmonary function ,6-minute walking distance, baseline dyspnea index, BMI and ellipsis were evaluated and compared between pre and post-training. Results After 12-weeks of different intensity of the upper and lower extremities,compared with lower exercise intensity group, higher exercise intensity group were improved significantly on 6minute walking distance and dyspneic symptom( P ＜ 0.01 ), but lost were high (P ＜ 0.05 ). The pulmonary function, BMI were not increased between pre and post-training. Conclusion The two different intensity of the upper and lower extremities were proved to be effective for improving the dyspneic symptoms and exercise tolerance with stable elderly COPD patients. Compared with lower exercise intensity group, higher exercise intensity group were improved significantly, but lost were high. The pulmonary function, BMI were not increased between pre and post-training.
