六分钟步行运动对慢性阻塞性肺疾病患者生活质量的影响

Six-minutes' Walk Training on Patients' Quality of Life with Chronic Obstructive Pulmonary Disease

目的探讨六分钟步行运动对慢性阻塞性肺疾病(COPD)患者生活质量的影响。方法将86例中重度COPD缓解期患者随机分为训练组和对照组。训练组患者每天进行1次六分钟步行运动训练,为期12个月;对照组仅接受常规药物治疗。比较治疗前后两组患者的步行距离、生活质量及急性加重的差异。结果训练组患者的六分钟步行距离由(285±33.7)m增加到(365±41.6)m,CAT评分由(21.2±5.4)分降至(14.2±4.6)分,均较干预前明显改善,差异有统计学意义(P<0.01);明显优于对照组,差异有统计学意义(P<0.05)。训练组急性加重次数较对照组明显减少(1.61±1.47)vs.(2.69±2.03),差异有统计学意义(P<0.05)。结论六分钟步行运动能有效改善COPD患者的生活质量,减少急性加重,适合社区开展。

Objective To explore the effect of six-minutes＇ walk training on patients＇ quality of life with chronic obstruc- tive pulmonary disease（COPD）. Methods 86 patients in remission with moderate or severe COPD were randomly divided into ei- ther exercise group or control group. The patients in training group received six-minutes＇ walk exercise once a day for 12 months; while the control group only accepted conventional drug treatment. Patients＇ walking distance, quality of life and acute exacerbation were compared between two groups before and after the treatment. Results In exercise group, patients＇ walking distance with six minutes improved from （285±33.7 ）m to（ 365 ± 41.6 ）m, and the CAT scores decreased from（ 21.2 ± 5.4 ）points to （ 14.2± 4. 6 ） points compared with before, the difference was statistically significant（ P 〈 0.01 ） ;At the same time both were better than control group,the difference was statistically significant（P 〈0. 05 ）. The number of exacerbations of patients in exercise group decreased significantly than the control group（ 1.61 ± 1.47 ） vs. （ 2. 69 ± 2. 03 ）, the difference was statistically significant（ P 〈 0. 05 ）. Con- clusion Six-minutes＇ walk training can effectively improve the quality of life of patients with COPD and reduce the acute exacer- bation, which is suitable for communities.
