The purpose of this study was to analyze the effects of a home exercise program on physical work capacity and dyspnea during activities of daily living in patients with severe chronic obstructive pulmonary disease. Twenty patients with severe respiratory impairment were assigned in a stratified, random manner to an Exercise Group (n = 10) or a Control Group (n = 10). Patients in the Exercise Group performed the supervised home exercise program of daily mobility, strengthening, and endurance exercises. Patients in the Control Group were visited regularly by a physical therapist but did not follow the exercise program. Six patients were eliminated from the study, either because of death (n = 1) or noncompliance with experimental conditions (n = 5), leaving each group with seven patients. The results of a progressive bicycle ergometer test after 18 weeks showed a significant between-group difference in physical work capacity. The physical work capacity of patients in the Exercise Group had improved 3% and had deteriorated 28% for patients in the Control Group (p less than .05). The symptom-limited multistage step test and the Chronic Respiratory Disease Questionnaire showed no difference in the patients' physical work capacity or dyspnea during ADL. Although not conclusive, this study yielded some evidence for the beneficial effects of home exercise training on patients with severe chronic obstructive pulmonary disease.
本研究的目的是分析家庭锻炼计划对重度慢性阻塞性肺疾病患者日常生活活动中的身体工作能力和呼吸困难的影响。20例重度呼吸功能障碍患者被分层随机分配至运动组（n = 10）或对照组（n = 10）。运动组患者进行了包括日常活动能力、强化和耐力锻炼的有监督的家庭锻炼计划。对照组患者由物理治疗师定期探访，但未遵循锻炼计划。6例患者被排除出研究，其中1例因死亡，5例因不遵守实验条件，最终每组各有7例患者。18周后进行的渐进式自行车测力计测试结果显示，两组在身体工作能力方面存在显著差异。运动组患者的身体工作能力提高了3%，而对照组患者则下降了28%（p < .05）。症状限制多级台阶测试和慢性呼吸系统疾病问卷显示，患者在日常生活活动中的身体工作能力或呼吸困难没有差异。尽管尚无定论，但本研究为家庭锻炼训练对重度慢性阻塞性肺疾病患者的有益影响提供了一些证据。
