Background. Multiple Sclerosis (MS) is a chronic autoimmune demyelinating disease. Muscle weakness, tremors, balance disorders, and gait instability are observed in MS patients. Also, respiratory muscles weakness can lead to decreased respiratory capacity, resulting in pneumonia and acute respiratory failure. Objectives. This study evaluates thoracic kyphosis angle (TKA) and respiratory functi...
Background and Objective: Immobility has unfavorable effects on our body physiology, including the respiratory system. The aim of this study was to investigate the effect of physical training course on pulmonary function during the course of one semester, using respiratory function indices by the spirometric test in female students at Zanjan University of Medical Sciences (ZUMS). Materials and ...
Background: Asthma is a life-threatening disease that can cause death due to bronchospasm. In addition to clinical symptoms such as wheezing, acute paroxysmal dyspnea, chronic cough after exposure to cold air or cough after exercise, spirometry is also necessary for the diagnosis of asthma. The association between respiratory symptoms and a positive methacholine challenge test (MCT) is still co...
