dc.titleA comparison of the effectiveness of two methods of inspiratory muscle training in patients with chronic obstructive airway diseaseen_US
dcterms.abstractThe purpose of this study was to evaluate the effectiveness of two commonly used inspiratory muscle training (IMT) methods - the inspiratory resistive breathing (IRB) and the threshold loading (TL) in a group of patients with chronic obstructive airway disease (COAD) participating in a pulmonary rehabilitation program (PRP). IMT was performed by using two commercially available IRB and TL devices. The study adopted a multi-group pretest-posttest control group design. After recruitment into the PRP, thirty-seven COAD subjects were randomly divided into three groups. In addition to their PRP training, 13 patients received IRB training, 12 patients received TL training, and 12 patients received sham TL training (control group). The inspiratory muscle strength and endurance, general exercise capacity, level of dyspnoea after exercise and aspects of quality of life (QOL) were compared. After six weeks of training, IMT was shown to be effective in improving the inspiratory muscle strength and endurance, and the dyspnoea dimension of the QOL. The improvement in the inspiratory muscle performance was greater in the TL group than in the IRB group, and was explained by a higher inspiratory flow rate achieved during training with the TL device. It was concluded that IMT was able to augment the inspiratory muscle strength and endurance in patients undergoing a pulmonary rehabilitation program. The TL device was found to be more effective than the IRB device in this task. Improvement in exercise capacity and level of dyspnoea, however, was not superior to that achieved by the control group which participated in the pulmonary rehabilitation program alone.en_US
