About
Severe dyspnea, cough, fatigue, restrictive type ventilation disorder, decreased pulmonary function, impaired gas exchange, decreased cardiovascular function and exercise intolerance are frequently encountered findings in patients with interstitial lung disease. It was demonstrated exercise training has beneficial effects in patients with interstitial lung disease. However, no study investigated the effects of upper extremity aerobic exercise training on outcomes in patients with interstitial lung disease.
Full description
Interstitial lung diseases (ILD) are a heterogeneous group of diseases that cause significant mortality and morbidity worldwide. As a result of the chronic inflammatory process in this disease, structural and mechanical pulmonary disorders develop, which are considered the main causes of deterioration in cardiopulmonary functions. Interstitial lung patients have a decrease in both static and dynamic lung volumes and carbon monoxide diffusing capacity (DLCO). As a result of this pathological mechanism, effort dyspnea and an increase in exercise intolerance occur. Therefore, individuals with ILD tend to avoid activities that increase shortness of breath, resulting in decreased physical activity levels and an increased sedentary lifestyle. Individuals whose functional exercise capacities are also limited due to this vicious circle become more dependent in their daily living activities. In addition, peripheral muscle dysfunction is another important factor that causes exercise intolerance in individuals with all chronic lung diseases, including ILD. One of the most important mechanisms triggering peripheral muscle dysfunction in ILD is hypoxia which develops with desaturation. Hypoxia, which causes an increase in oxidative stress, is one of the factors that can cause muscle dysfunction. It has been reported that upper extremity exercise capacity and functional performance are low in individuals with advanced ILD, and it has been stated that upper extremity exercise training may be beneficial in these patients.
However, the effects of upper extremity aerobic exercise training have not been investigated in the literature in patients with ILD. In this context, the primary aim of our study is to investigate the effects of upper extremity interval aerobic exercise training applied to patients with ILD on oxygen consumption, muscle oxygenation, and physical activity level. The secondary aim of the study is to determine the effects of this training on upper extremity functional exercise capacity, respiratory functions, pulmonary diffusion capacity, respiratory and peripheral muscle strength, inspiratory muscle endurance, dyspnea, fatigue, quality of life, sleep quality, anxiety, and depression. For this purpose, our study was planned as a randomized, controlled, three-blind (investigators, patient, and analyzer) prospective study. According to the block randomization result, at least 21 patients with a diagnosis of ILD will be included in the training and control groups.
The training group will be given upper extremity interval aerobic exercise training with arm ergometer for 30-45 minutes 3 days a week for 6 weeks, and the control group will not be given any training during the study. After the study, the treatment applied to the training group will also be applied to the control group in order to ensure that the patients in the control group are not ethically deprived of rehabilitation.
All assessments will be completed in two days, before and after six weeks of training.
