Abstract

Objective 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).Design A single-blind, randomized controlled trial.Setting Five general outpatient clinics in Hong Kong.Intervention 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.Outcomes Lung functions, 6-min walk test, and COPD exacerbation rate.Results 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.Conclusion 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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
