THE CORELATION BETWEEN GRIP MUSCLES’ STRENTGH AND A LEVEL OF FUNCTIONAL ABILITY AMONG THE ELDERLY WOMEN IN TISTA KERAMBITAN, TABANAN
The aging process affects the skeletal muscle structure and disability of the musculoskeletal system which resulted in limited and slowed motion. One characteristic of the aging process is a decrease in muscle strength. Muscle strength affects almost all daily activity. Decreased muscle strength can lead to limitations in daily activities, independence and quality of life. This study aims to determine the relationship between handgrip muscles’ strength and level of functional ability among elderly women in Tista, Kerambitan Tabanan. To assess the strength of the relationship and assess the direction of the relationship between the variables. The research design was used cross sectional study with Simple Random Sampling and got 73 samples. The strength of handgrip muscles was measured using Hand-grip dynamometer, while the functional independence level was assessed by Intermediate Activity Daily Living (IADL) questionnaire interview. Result of research by using Spearman correlation test got value P = 0,000 (P <0,05) and Coefficient correlation value equal to 0,489 indicate that there is a significant correlation between handgrip muscles’ strength with functional ability independence level, this relation is positive and medium. In conculsion that handgrip muscles’s strength and level of functional ability are positively correlated and medium. The stronger the muscle strength of the handgrip, the higher the level of functional ability independence and vice versa. Therefore, handgrip muscle’s strength can be used in identifying disabilities in the elderly.
