About

The aim of this clinical trial is to evaluate, the effects of inspiratory muscle training program in inspiratory muscle function, functional capacity, quality of life, lung function, breathing pattern and chest wall motion in patients with advanced lung disease. Patients were evaluated before the inspiratory muscle training, after 8 weeks of training and at follow-up which was performed 3 months after the end of the intervention.

Full description

Inspiratory Muscle Training (IMT) should be considered an additional intervention in the pulmonary rehabilitation program for patients with advanced lung disease. The aim of this study is to evaluate, the effects of inspiratory muscle training program in inspiratory muscle function, functional capacity, quality of life, lung function, breathing pattern and chest wall motion in patients with advanced lung disease. It is a quasi-experimental study with longitudinal design. Patients with advanced lung disease from the advanced lung disease and pre lung transplantation ambulatory performed home-based high intensity interval IMT for 8 weeks (two sessions per day, daily). In each session patients executed two times 30 breaths with one-minute rest between them. Resistance was set to the highest tolerable according to scores pointed by the patient on the Borg score (between 4 and 6) aiming 50% of actual pimax or higher. An experienced physiotherapist was responsible for weekly adjustments on the resistance of training as well as new assessment of maximal inspiratory pressure. Patients were evaluated before the inspiratory muscle training, after 8 weeks of training and at follow-up which was performed 3 months after the end of the intervention. Patients were evaluated by the same experienced researcher in all three moments of the study. Evaluations were performed in the Laboratory of research and evaluation of cardiorespiratory performance of Federal University of Minas Gerais.
