Title: Soft-hard Technologies to Assistance and Accessibility in Patients With Chronic Diseases: The Effect of a Five Week Electrical Myostimulation Program.
Brief Summary: Patients afflicted with Chronic Heart Failure (HF) typically do not maintain stable cardiac function for the remainder of their life and consequently require continuous medical management and intermittent hospital admissions. Several investigations have demonstrated that electrical muscle stimulation (EMS) produces positive physiologic and psychological adaptations in patients with HF. However not all the EMS modalities were been evaluated on this population or not even were tested based on present recognized gold standard clinical parameters after a short period of treatment. The primary aims of the proposed study is to: Determine the effect of a five week home based of three EMS modalities on prognostics markers, perceived quality of life, muscle force and electrical activity in subjects diagnosed with HF.
