Effects of Inspiratory Muscle Training in Patients With Advanced Lung Disease (IMTinALD)

18 de abril de 2018 actualizado por: Veronica Franco Parreira, Federal University of Minas Gerais

Effects of Inspiratory Muscle Training in Inspiratory Muscle Function, Functional Capacity, Quality of Life, Lung Function, Breathing Pattern and Thoracoabdominal Motion in Patients With Advanced Lung Disease

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.

Descripción detallada

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.

Experimental: IMT group

Group intervention: home-based interval inspiratory muscle training:

  • during 8 weeks (two sessions per day, daily)
  • two times 30 breaths with one-minute rest between them in each session
  • training resistance set to the highest tolerable load according to scores pointed by the patient on the Borg score (between 4 and 6) aiming 50% of actual pimax or higher adjusted in the supervised weekly session
Breathing through a device that offers resistance during inspiration. In this study the POWERbreathe device was used (POWERbreathe® K3, HaB International Ltd, UK).

London chest activity of daily living scale (total score) - It evaluates the dyspnea in daily activities. Consists in a 15 questions questionnaire with scores from 0-5 in each question. Total score varies from 0 to 75, the higher the score the major the limitation on daily activities due to dyspnea.
