Evaluation of Utility Quadriceps Magnetic Stimulation in COPD (Chronic Obstructive Pulmonary Disease) Patients After Hospital Exacerbation

The aims of this study are:1.To evaluate the utility of quadriceps RMNMS (repetitive magnetic neuromuscular stimulation) in the evolution of COPD patients after hospital admission for acute exacerbation.2 To evaluate the time schedule of recovery changes in muscle parameters ,exercise capacity and quality of life after acute exacerbation. 3.To test the use of this new method of training in acute clinical situations. Patients: COPD patients admitted to the Hospital with acute exacerbation. Group 1: RMNMS Treatment .Group 2 : sham RMNMS treatment. Randomized assignment by minimization method. PROTOCOL Training Group: 10 days after discharge and during 8 weeks, 2-3 days/week. Measures: Spirometry, Plethysmography ,Diffusion Test. Main outcomes: Exercise test (Six minutes walking distance). Muscle function: MVC. Health related quality of life.
