设计：病例对照研究。研究对象：61名65岁的社区老年人，在没有辅助设备的情况下具有独立行走的能力。方法：受试者完成了3项平衡表现测试：不稳定板平衡测试、功能伸展测试和计时起跳。为了进行分析，根据前一年跌倒的历史将受试者分为跌倒者和不跌倒者，并对两组的表现结果进行比较。然后将跌倒者与非跌倒者(性别、年龄、体重和身高)进行1：1匹配，计算每次测试的最佳截止点分数和受试者操作特征曲线下面积(AUC)。结果：功能触觉测试和Timed Up and Go不能可靠地区分跌倒者和非跌倒者。相比之下，不稳定板平衡测试的得分在两组之间有显著差异(p=0.040)。在所有3项测试中，不稳定平衡板试验的AUC最大(0.78)，灵敏度(0.67)和特异度(0.87)均较高。结论：对于高功能老年人，不稳定平衡板试验有助于区分步履蹒跚的人和不跌倒的人。
Objective: To determine the usefulness of an unstable board balance test in identifying a fall history among high-functioning community-dwelling elderly individuals.Design: Case-control study.Subjects: Sixty-one community-dwelling elderly aged >= 65 years and having the capacity to walk independently without an assistive device.Methods: Subjects completed 3 balance performance tests: the Unstable Board Balance Test, Functional Reach Test, and Timed Up and Go. For analysis, subjects were classified as fallers or non-fallers based on the history of falls over the previous year, and performance outcomes were compared between the 2 groups. Subjects classified as fallers were then matched 1:1 with non-fallers (for sex, age, body weight and height), and the optimal cut-off score and area under the receiver operating characteristic curve (AUC) for each test were calculated.Results: Functional reach test and Timed Up and Go did not reliably discriminate between fallers and non-fallers. In contrast, the score on the unstable board balance test was significantly different between the 2 groups (p = 0.040). Among all 3 tests, AUC was largest for the unstable board balance test (0.78), with superior sensitivity (0.67) and specificity (0.87).Conclusion: For high-functioning elderly subjects, the unstable board balance test was useful in discriminating between falters and non-fallers.
