目的 检验Tetrax测试系统在老年人平衡功能测试中的重测信度。方法 对22名符合入选条件的老年人(66～84岁)，应用Tetrax测试系统测定受试者睁眼自然站立状态下的稳定性指数、姿势摆动频谱和体重分布状态。1周后同一时间南同一测试者重复测试1次。采用组内相关系数(ICC)分析两次测试的重测信度。结果 平衡功能测试的各个指标ICCs=0.797～0.882(P＜0.01)。结论 Tetrax平衡测试系统用于老年人平衡功能评估时具有较高的重测信度。%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.
