Abstract:
Objective To assess the test-retest reliability of Tetrax posturographic balance assessment system in determining the balance function in elderly individuals. Methods 22 elderly subjects (66~84 years old) were measured with the stability index (ST), the spectrum analysis of postural sway and the weight distribution harmony between two foots or heels and toe parts in standing on solid surface with eyes open using Tetrax balance system. All tests were repeated 1 week after the initial test and each subject underwent the test under the same instructions and conditions. The intraclass correlation coefficients (ICC) were used to determine the test-retest reliability. Results ICC of all balance functional parameters ranged from 0.797~0.882 (P<0.01). Conclusion The posturographic balance assessment system has good test-retest reliability for determining the balance function in elderly people.
