Duchenne muscular dystrophy (DMD) is a progressive neuromuscular disease that severely impairs respiratory muscle function. Diagnosis of DMD involves genetic testing and muscle biopsies, while monitoring of respiratory function is done through spirometry and other respiratory tests. Breathing exercises are crucial for patients with DMD and include diaphragmatic and thoracic breathing, as well as assisted methods such as non-invasive ventilation. These exercises help maintain airway patency, improve lung capacity, and reduce the risk of respiratory infections. In addition to breathing exercises, DMD treatment includes the use of cortiosteroids, physiotherapy, orthopedic interventions, and mechanical breathing assisted in later stages. By engaging the respiratory muscles through these exercises, the process of their degeneration can be slowed down and the need for inventive ventilation methods can be reduced. Successful implementation of breathing exercises and treatment requires a multidisciplinary approach and education of the patient and their families. A comprehensive approach to diagnosis, exercise and treatment enables patients with DMD to have a better quality of life, reduce the risk of complications and increase their life expectancy.
