Sarcopenia in the Acute Stroke

Regardless of the cause of immobilization, within days or weeks there is rapidly a decrease in strength and muscle mass, which can lead to sarcopenia. In severe strokes, immobilization and neurologic damage may be added to promote sarcopenia. Several studies in Asian populations confirm rapid increases in sarcopenia rates after stroke, but there are only rare data in Western populations. The aim of this work is to monitor during the first 10 days after a severe stroke leading to a reduction in ambulation, the evolution of muscle strength (studied in dynamometry), body composition (studied by impedance measurement) and sarcopenia rates. Investigators will also look for factors that predict the occurrence of this sarcopenia (such as sex, age, initial deficiency, stroke volume, swallowing disorders, etc.).
