Title: Functional and Cognitive Impairment Prevention Through Early Physical Activity for Elderly Hospitalized Patients: a Randomized Clinical Trial
Brief Summary: The current model of care for the hospitalized elderly patients has been conditioned by many factors unrelated to the disease process that caused the hospitalization and usually worsen the outcome of hospitalization circumstances. Many times hospitalized elderly patients spend most of the time in bed (even higher than 83% of bed rest versus 4% of those who stand or are walking). These patients have their functional and physiological reserve reduced which makes them more vulnerable to the effects of being bedridden. The consequences are at multiple levels emphasizing the functional loss or cognitive impairment, longer stays, mortality and institutionalization, delirium, deconditioning, pressure ulcers and decreased caloric intake, social isolation, poor quality of life and increased use of resources related to health. Exercise training can prevent functional and cognitive decline and modify even the posterior trajectory.
