With regard to respiratory problems, there are still no precise data on the long-term consequences of pulmonary fibrosis and therefore related to the insufficient functioning of the lung. It is possible to hypothesize that these deficiencies can be treated with one specific respiratory rehabilitation aimed at reducing dyspnea and difficulty in practicing daily activities and moving around. In fact, the scientific literature indicates that respiratory rehabilitation improves the quality of life and exercise tolerance of patients with IPF (idiopathic Pulmonary Fibrosis), by reducing respiratory deficits, hypotrophy and muscle weakness, physical deconditioning. Respiratory rehabilitation means a "multidisciplinary intervention based on scientific evidence for patients with chronic respiratory disorders who are symptomatic and often have a reduced quality of life, in need of aerobic and respiratory muscle training, but also oxygen, nutritional, educational, psychological support as well as therapeutic education. For all these reasons we have decided to start our blinded, single-center randomized controlled study, the details of which will be specified later.
