Improved Functional Performance in Geriatric Patients During Hospital Stay

Objective: The aim of this work was to evaluate the time course of changes in strength and functional performance in elderly hospitalized medical patients. Design: This was a prospective observational study in elderly medical patients of age 65 years or older at a geriatric department. Measurements were obtained on days 2 to 4, day 5 to 8, and days 9 to 13. Functional performance was measured with De Morton Mobility Index (DEMMI) test and a 30-second chair stand test (30-s CST). Muscular strength was measured with handgrip strength. Activity level was determined with accelerometry (ActivPAL). Results: Results in DEMMI and 30-s CST gradually improved (P 0.05). Larger functional improvements were observed in patients with "high" compared to "low" and "moderate" activity level (P
