Relationship between dynapenia, sarcopenia and functional mobility in institutionalized frail elderly

Abstract

Introduction: Among the disabling events with advancing age, there is the Frail Elderly Syndrome (FES), resulting in a higher risk of falls, disability, hospitalization and even death. Objective: verify the relationship between dynapenia, sarcopenia and functional mobility of institutionalized frail elderly. Methods: A descriptive correlational study was conducted with 26 institutionalized elderly men and women with average 82,3 ±6 years. All participants had three or more fragile characteristics according to established criteria. Measuring instruments used as inclusion criteria were the Mini Mental State Examination and the Geriatric Depression Scale. As specific instruments were International Physical Activity Questionnaire, Timed Up and Go Test, handgrip dynamometer, handheld dynamometer to assess large muscle groups and the Lee equation to estimate the total muscle mass. Results: Functional mobility correlated significantly only with muscle strength measurements (handgrip r-0,50, upper limbs 0,59, lower limbs r-0.61 and the appendicular muscle strength, considering the four limbs r-0.63). Conclusion: Programs for prevention and treatment of FES depend on accurate clinical diagnosis. The accuracy of the evaluation of muscle strength is essential, and the use of dynamometry can make a decisive contribution for this purpose
