Acute Effect of Whole-body Electrical Stimulation in COPD Patients

Patients with chronic respiratory diseases present in addition to respiratory symptoms, peripheral muscle dysfunction, which contributes to functional impairment. The aim of the study is to investigate the safety of whole-body electrical stimulation in patients with chronic obstructive pulmonary disease (COPD). Patients will perform two whole body electrostimulation protocols, with an interval of one week between them. The primary outcome will be the safety of electrical stimulation through peripheral oxygen saturation, respiratory rate, systolic blood pressure, diastolic blood pressure, heart rate, dyspnea and fatigue (Borg subjective perceived exertion scale), autonomic control (rate variability cardiac arrest) and occurrence of adverse events. Secondary outcomes will be muscle damage assessed by serum creatine kinase level, muscle fatigue assessed by serum lactate level, delayed onset muscle soreness assessed by visual numerical scale, and peripheral muscle strength by dynamometry.
