Abstract: Extract Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of morbidity, mortality, and disability worldwide. While it is primarily characterized by persistent, non-fully reversible airflow limitation, COPD is now recognized as a systemic disease with extrapulmonary manifestations [1]. Among these, impaired functional performance -reflected in difficulty standing from a seated position, stair climbing or fast walking for everyday chores- leads to higher fall risk, reduced independence, and poorer quality of life [2]. Importantly, these deficits often occur even in the absence of resting hypoxemia. Contributing factors include skeletal muscle weakness, impaired balance and coordination [3].
