The Correlation between Strength of Handgrip and Muscle Mass with Elderly Functional Mobility at the Elderly Integrated Service Center in Pekauman Primary Health Care, Banjarmasin, Indonesia

Abstract

Ageing is the progressive loss of tissue and organ function over time, which one is loss of muscle fiber (sarcopenia). Gait speed is one of the important indicators to measure functional ability. Functional mobility of the elderly is the ability of the elderly to make movements for activities including activities to meet the elderly's self needs, including independence in self-care. Muscle mass decreased is an important factor that results in decreased muscle strength and muscular endurance. Muscle strength decreased and muscular endurance in the lower limbs is related to functional abilities, especially mobility abilities such as walking speed decreased, balance decreased and increased in risk of falls. This study aims to analyze the correlation between the handgrip strength and muscle mass with elderly functional mobility at the Elderly Integrated Service Center in Pekauman Primary Health Care, Banjarmasin, Indonesia. This method used in this study is analytic observational with cross-sectional approach. Sample taken by total sampling technique with number of sample were 60 people. The Pearson test results have a significant positive correlation with moderate strength between hand grip strength and functional mobility as measured by using the gait speed test (4-meter) (p = 0.000, r = 0.415) and significant negative correlation with weak strength between grip strength hands and functional mobility were measured using TUG (p = 0.015, r = -0.281). This study also showed that there was a significant positive correlation with moderate strength between muscle mass and functional mobility measured using the gait speed test (4-meter) (p = 0.000, r = 0.491) and a significant negative correlation with weak strength between muscle mass and functional mobility were measured using TUG (p = 0.004, r = -0.342). This means that the stronger the handgrip strength and muscle mass of a person, the better functional mobility.
