초록

Purpose: The aim of this study was to establish an association between grip strength and gait variability in the elderly.
Methods: The participants in this experiment (n = 20) were aged 65 or older. Power grip and lateral pinch forces wereobtained in grip strength tests, and spatiotemporal gait parameters were collected from IMU sensors during 6 min actualwalking to test the gait of participants. The collected gait parameters were converted to coefficient of variation (CV)values. To confirm the association between grip strength and gait variability, a partial correlation analysis was conductedin which height, weight, and gait speed were input as controlling variables.
Results: Grip power showed a significant negative correlation with the stride length CV (r = -0.52), and the lateralpinch force showed a significant negative correlation with the stance CV (r = -0.65) and swing CV (r = -0.63).
Conclusion: This study reveals that gait variability decreases as grip strength increases, although height, weight, andgait speed were controlled. Thus, grip strength testing, a simple aging evaluation method, can help identify unstablegait in older adults at risk of falling, and grip strength can be utilized as a non-invasive measurement method for frailtymanagement and prevention.
