平衡障碍是福尔斯跌倒减少不活动的最大风险因素之一，导致护理。因此，平衡能力对维持老年人独立的日常生活活动至关重要。已经开发了许多评估平衡能力的测试。然而，很少有报告揭示结构的平衡性能测试比较年轻人和老年人的结果。协方差结构分析是一种用于统计检验析因结构是否适合数据的工具。本研究探讨了年龄对平衡能力测试的因子结构的影响。参与者包括60名年龄为22 ± 3岁的健康年轻女性（年轻组）和60名年龄为69 ± 5岁的社区老年女性（老年组）。采用六种平衡测试：姿势摇摆、单腿站立、功能性伸展、定时起身和行走（TUG）、步态和EquiTest。探索性因素分析显示，三个明确的解释因素中提取的年轻组。第一个因子在EquiTest上具有高负荷，并被解释为“反应性”。第二个因素在姿势摇摆试验中具有高载荷，并被解释为“静态”。第三个因素在TUG和步态测试中具有高负荷，并被解释为“动态”。同样，在老年组中提取了三个可解释的因素。第一个因素在姿势摇摆测试和EquiTest上具有高载荷，因此被解释为“静态和反应性”。第二个因子在EquiTest上具有高负荷，被解释为“反应性”。第三个因素，TUG和步态测试的高负荷，被解释为“动态”。对试验数据应用协方差结构模型：二阶因素为平衡能力，一阶因素为静态、动态和反应性因素，假设这些因素是基于6次平衡试验测量的。模型拟合优度指数（GFI）在可接受范围内（青年组GFI=0.931;老年组GFI=0.923）。与平衡能力有关的静态、动态和反应性因子在青年组中的负荷分别为0.21、0.24和0.76，在老年组中的负荷分别为0.71、0.28和0.43。结果表明，平衡能力的共同因子结构为静态、动态和反应性，青年人的反应性平衡能力主要由平衡能力来表征和解释，而老年人的反应性平衡能力主要由静态平衡能力来表征和解释。
Balance impairment is one of the biggest risk factors for falls reducing inactivity, resulting in nursing care. Therefore, balance ability is crucial to maintain the activities of independent daily living of older adults. Many tests to assess balance ability have been developed. However, few reports reveal the structure underlying results of balance performance tests comparing young and older adults. Covariance structure analysis is a tool that is used to test statistically whether factorial structure fits data. This study examined aging effects on the factorial structure underlying balance performance tests. Participants comprised 60 healthy young women aged 22 ± 3 years (young group) and 60 community-dwelling older women aged 69 ± 5 years (older group). Six balance tests: postural sway, one-leg standing, functional reach, timed up and go (TUG), gait, and the EquiTest were employed. Exploratory factor analysis revealed that three clearly interpretable factors were extracted in the young group. The first factor had high loadings on the EquiTest, and was interpreted as 'Reactive'. The second factor had high loadings on the postural sway test, and was interpreted as 'Static'. The third factor had high loadings on TUG and gait test, and was interpreted as 'Dynamic'. Similarly, three interpretable factors were extracted in the older group. The first factor had high loadings on the postural sway test and the EquiTest and therefore was interpreted as 'Static and Reactive'. The second factor, which had high loadings on the EquiTest, was interpreted as 'Reactive'. The third factor, which had high loadings on TUG and the gait test, was interpreted as 'Dynamic'. A covariance structure model was applied to the test data: the second-order factor was balance ability, and the first-order factors were static, dynamic and reactive factors which were assumed to be measured based on the six balance tests. Goodness-of-fit index (GFI) of the models were acceptable (young group, GFI=0.931; older group, GFI=0.923). Static, dynamic and reactive factors relating to balance ability had loadings 0.21, 0.24, and 0.76 in the young group and 0.71, 0.28, and 0.43 in the older group, respectively. It is suggested that the common factorial structure of balance abilities were static, dynamic and reactive, and that for young people reactive balance ability was characterized and explained by balance ability, whereas for older people it was static balance ability.
