Whole-body Vibration on Mucus Clearance, the Quality of Life, and Exercise Capacity for Patients With Chronic Obstructive Pulmonary Disease

Not Applicable
Completed
Conditions
COPD
Interventions
Device: A vertical vibration platform PowerVibe Zen Pro 5900
Device: HFCWO
Registration Number
NCT04952363
Lead Sponsor
Kaohsiung Medical University Chung-Ho Memorial Hospital
Brief Summary

Although whole body vibration (WBV) is mainly designed to promote neuromuscular function, however, because of its vibration characteristics, whether it can provide additional effects on the sputum clearance for chronic obstructive pulmonary (COPD) disease patients, thereby improving the quality of life, and exercise capacity is still unknown.

Primary Outcome Measures
NameTimeMethod
chronic obstructive pulmonary disease assessment test (CAT)8 weeks

questionnaire of COPD symptoms, scores ranging from 0 to 40, higher scores indicating more severe impact of COPD on their life

FVC(% pred)8 weeks

percentage of predicted FVC value (% pred)

1 min STST8 weeks

the number of repetitions performed in the 1-min sit-to-stand test (rep.)

FVC8 weeks

forced vital capacity tested in pulmonary function test (Liters)

Distance-Saturation Product (DSP)8 weeks

the product of distance walked and lowest oxygen saturation during the 6-min walk test (m%)

FEV1/FVC8 weeks

forced expiratory volume in 1 second divided by forced vital capacity in pulmonary function test (%)

Predicted distance8 weeks

percentage of the predicted 6 minute walk test distance (%pred)

5-rep STST8 weeks

the complete time for the 5-repetition sit-to-stand test (sec)

Muscle strength test28 weeks

maximal force output for quadriceps muscle (lbs)

X-ray score8 weeks

the evaluation of the chest radiography based on the sputum impaction score, scores ranging from 0 to 18. A decrease in score represented an improvement in sputum in each area.

modified Medical Research Council (mMRC)8 weeks

questionnaire of dyspnea, scores ranging from 0 (low degree of dyspnea) to 4 (high degree of dyspnea)

Saint George Respiratory Questionnaire (SGRQ)8 weeks

questionnaire of overall health, daily life, and perceived well-being, scores ranging from 0 (no health impairment) to 100 (maximum health impairment)

FEV18 weeks

forced expiratory volume in 1 second in pulmonary function test (Liters)

FEV1(% pred)8 weeks

percentage of predicted FEV1 value (% pred)

6 min walk distance8 weeks

the distance walked in 6 minutes (m)

Muscle strength test18 weeks

Maximal force output for biceps femoris muscle (lbs)

Sputum self-assessment scale8 weeks

questionnaire of sputum volume, it contained three items (0-25 mL/d, 25-50 mL/d, and 50-100 mL/d) as a checklist
