Respiratory Physiotherapy

This experimental pre-post intervention study aims to evaluate the effect of a respiratory physiotherapy and combined strength and cardiovascular training program on muscle oxygen saturation and functional capacity in patients with Chronic Obstructive Pulmonary Disease (COPD). Oxygenation of the intercostal, quadriceps, and triceps surae muscles will be assessed using near-infrared spectroscopy (NIRS) during standard physical performance tests (6-Minute Walk Test and 30-Second Chair Stand Test). Additional functional parameters and quality of life will be recorded pre- and post-intervention. The results will contribute to optimizing rehabilitation programs and monitoring intensity and progress through muscle oxygenation data.
