Design outcomes

Primary

MeasureTime frameDescription
Changes of CAT{Chronic obstructive pulmonary disease(COPD) Assessment Test} scoresscreening, 6, 12 weekCAT were measured in study screening, visit 2(6 week), visit 3(12 week). CAT was developed for use as a way to assess the quality of life of COPD patients, consisting of eight items, each of which evaluates 0 to 5 points, and the sum of all eight item scores is the CAT score. The best quality of life is 0 points, and the worst is 40 points.
Changes of BCSS(Breathlessness, Cough, and Sputum Scale) scores0, 6, 12 weekBCSS were measured in study visit 1(0 week), visit 2(6 week), visit 3(12 week). BCSS is a scale for evaluating symptoms of Breathlessness, cough, and sputum, which is a major symptom of COPD(Chronic obstructive pulmonary disease), and symptoms of Breathlessness, cough, and sputum are evaluated in five stages. \<Breathlessness, sputum\> 0: never, 1: rare, 2: occasionally, 3: often, 4: almost always \<Cough\> 0: never, 1: a little hard, 2: moderate extent of hard, 3: over moderate extent of hard, 4: serious hard

Secondary

MeasureTime frameDescription
FVC(Forced vital capacity)screening, 12 weekThe Forced vital capacity(FVC) was measured Flow rate discharged during the hard-working unit before and after the intervention.
FEV1(Forced expiratory volume in 1 second)screening, 12 weekThe Forced expiratory volume in 1 second(FEV1) was assessed before and after the intervention.
