Abstract
Background: Chronic Obstructive Pulmonary Disease (COPD) resulting in alterations which leads to thoracoabdominal asynchronism (TA) mainly during daily life activities. However, there is no scientific evidence that the inspiratory muscle training(IMT) associated with the physical training (PT) could improve the TA of COPD.
Aims: to verify whether theIMT-PTcan improve theTA and dyspnea at rest and during unsupported upper limb (UUL) exercises and compare with PT alone (GPT).
Methods: Sixteen patients with COPD were divided into two groups: 9 in IMT-PT and 7 in the PT group. IMT was composed by breathing exercises (BE) in IMT trainer, 3 times a week, during 16 weeks and PT consisted of aerobic+calisthenics-and-BE.Patients were assessed on baseline and after intervention by respiratory inductance plethysmography to evaluate TA at rest and during UUL exercises (1: shoulder flexion until 90°; 2: until 180°) in the stand posture.
Results: Only IMT-PT showed significant reduction of TA and dyspnea (IMT-PT: pre 0.75(0-2)/ post 0(0-0); p<0.05) during these exercises after intervention. There was difference between groups only in PhAng index during exercise 1(IMT-PT: 39.6±19.5 versus GPT: 54.1±25.5; p<0.05, respectively).
Conclusion: the IMT+PT can beneficially modulate TA at rest and during UUL exercises. Recommendations of IMT may provide helpful tool to enhance TA.
