Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory disease characterized by persistent airflow limitation. The patients are suffering dyspnea year by year, resulting in the decreased exercise tolerance and quality of life. Patients with COPD often have both inspiratory muscles and expiratory muscle dysfunction. Respiratory muscle training was one of the widely used pulmonary rehabilitation method in COPD patients. Respiratory muscle training include inspiratory training ,expiratory training and concurrent inspiratory and expiratory muscle training . Both of the training methods are effective. However, the effects of these different types of respiratory muscle training method on the respiratory physiology and neural respiratory drive of COPD are still unclear. Therefore, the purpose of this study was to investigate the different effects of these respiratory muscle training methods on respiratory mechanics and central drive in COPD patients. Besides,the effect of the different respiratory muscle training methods was compared between patients with and without respiratory muscle weakness.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Diaphragmatic function | Diaphragmatic function can be assessed by diaphragm electromyogram(EMGdi) which reflect the physiological activity of the diaphragm and indicate functional status of the central drive. | Change from baseline in diaphragm electromyogram at the load of threshold (10 minutes later,20minutes later,30 minutes later, 40 minutes later) | |
Secondary | Respiratory pressure | Respiratory pressure parameter is transdiaphragmatic pressure ( Pdi) in cmH2O, which reflect the strength of diaphragm. | Change from baseline in respiratory pressure at the load of threshold (10 minutes later,20minutes later,30 minutes later, 40 minutes later) | |
Secondary | Respiratory volume | Respiratory volume parameter is minute ventilation (VE) in liter(L). | Change from baseline in respiratory volume at the load of threshold (10 minutes later,20minutes later,30 minutes later, 40 minutes later) | |
Secondary | respiratory work | respiratory work is associated with transdiaphragmatic pressure time product | Change from baseline in transdiaphragmatic pressure time product at the load of threshold (10 minutes later,20minutes later,30 minutes later, 40 minutes later) |
