To evaluate the effectiveness of a Tai chi Qigong (TCQ) program in enhancing respiratory functions and activity tolerance in clients with chronic obstructive pulmonary disease (COPD).
A single-blind, randomized controlled trial.
Five general outpatient clinics in Hong Kong.
In total, 206 COPD clients were randomly assigned into one of the three groups, namely, TCQ, exercise, and control group. Subjects in the TCQ group received a TCQ program consisting of two 60-min sessions each week for three months. Subjects in the exercise group were taught to practice breathing techniques combined with walking as an exercise. Subjects in the control group were instructed to maintain their usual activities. Data collection was performed at baseline and at the 6-week and 3-month marks.
Lung functions, 6-min walk test, and COPD exacerbation rate.
Results of repeated measures of analysis of covariance demonstrated that there were significant interaction effects between time and group in forced vital capacity (p=.002, η(2)=.06), forced expiratory volume in 1s (p<.001, η(2)=.02), walking distance (p<.001), and exacerbation rate (p=.006, η(2)=.06) at 3 months. Improvements were noted in the TCQ group. No changes were observed in the exercise group, while a decline in lung functions was noticed in the control group.
Tai chi Qigong was able to improve respiratory functions and activity tolerance level in COPD clients. The breathing and walking exercise helped maintain lung functions and slow down disease progression.
评估太极拳气功（TCQ）方案对慢性阻塞性肺疾病（COPD）患者呼吸功能和活动耐量的增强效果。
单盲、随机对照试验。
香港的五家普通门诊诊所。
共有 206 名 COPD 患者被随机分配到 TCQ 组、运动组和对照组三个组中，每组各 68 人。TCQ 组接受每周两次、每次 60 分钟的 TCQ 方案，共进行三个月。运动组的患者接受呼吸技术和散步相结合的运动训练。对照组的患者被要求保持其日常活动。数据收集在基线、6 周和 3 个月时进行。
协方差重复测量分析的结果表明，在 3 个月时，用力肺活量（p=.002，η(2)=.06）、1 秒用力呼气量（p<.001，η(2)=.02）、步行距离（p<.001）和恶化率（p=.006，η(2)=.06）方面，时间和组之间存在显著的交互效应。TCQ 组有明显改善。运动组没有变化，而对照组的肺功能则下降。
太极拳气功能够改善 COPD 患者的呼吸功能和活动耐量。呼吸和步行运动有助于维持肺功能并减缓疾病进展。
