Age-Related Hand Grip and Quadriceps Muscle Strength Ratio, Fall Risk, and Balance in Healthy Adults

Abstract Objectives The aim of this study is to examine the relationship between age-related hand grip and quadriceps muscle strength ratio, fall risk and balance in healthy adults, and also to show the interaction between these parameters. Methods 92 participants were examined in 6 groups as 18–29, 30–39, 40–49, 50–59, 60–69, 70 and older individuals. Fall risk, balance, grip strength and quadriceps muscle strength were evaluated. The correlation between the grip/quadriceps strength ratio (G/Q) and the risk of falling and balance was examined. Results There was no significant difference between G/Q and balance or fall risk in all age groups. In addition, it showed moderate and significant correlations with grip and quadriceps muscle strength, balance, and fall risk in groups aged 60 years and older. Conclusion It is not sufficient to use the ratio of hand grip strength and quadriceps muscle strength in different age groups to predict balance and fall risk. Various test combinations as well as different parameters such as lower extremity endurance and flexibility can be used to evaluate physiological fall risk and balance in the future studies.
