背景与目的：测试的稳定性和重测信度以前没有报告的平衡评估系统测试（BESTest）或迷你BESTest（mBEST）在老年人与非特异性平衡限制的人口。此外，没有标准识别变化大于机会已被报道在老年人与非特异性平衡问题使用BEST或mBEST评分。本研究的目的是确定随着时间的推移，测试的稳定性，重测信度，以确定最小的可检测变化的最佳和mBEST在老年人的非特异性平衡问题。此外，BESTest和mBEST识别过去跌倒者的能力被表征。方法：这是一项观察性研究，纳入了58名65岁或以上有福尔斯跌倒史或自我报告平衡问题的成人。在4周的开始和结束时对所有参与者进行BEST和mBEST。用组内相关性计算重测信度，并在95%置信水平（MDC 95）下计算最小可检测变化。受试者操作特征用于表征BESTest和mBEST的灵敏度和特异性，以识别以前跌倒过的老年人。结果：平衡分数在4周内没有显著变化。BEST est（0.86）和mBEST（0.84）的重测信度为良好至优秀。确定了BEST（8.9）和mBEST（4）的MDC 95评分。结论：在4周的时间内，BESTest和mBEST评分对于自我报告有平衡问题或跌倒史的老年人人群是稳定和可靠的。MDC 95评分可以解释康复后BESTest和mBEST评分的变化。
Background & Purpose: Test stability and test-retest reliability have not previously been reported for either the Balance Evaluation Systems Test (BESTest) or mini-BESTest (mBEST) in a population of older adults with nonspecific balance limitations. Furthermore, no criterion for identifying change greater than chance has been reported in older adults with nonspecific balance problems using either BESTest or mBEST scores. The purposes of this study were to determine test stability over time, test-retest reliability, to identify minimum detectable change for the BESTest and mBEST in a population of older adults with nonspecific balance problems. In addition, the ability of the BESTest and mBEST to identify past fallers was characterized. Methods: This was an observational study with 58 adults 65 years or older with a history of falls or self-reported balance problem. The BESTest and mBEST were administered to all participants at the beginning and end of 4 weeks. Test-retest reliability was calculated with intraclass correlations, and minimum detectable change was calculated at the 95% confidence level (MDC95). Receiver operating characteristics were used to characterize the sensitivity and specificity of the BESTest and mBEST to identify older adults who had previously fallen. Results: Balance scores did not significantly change over a 4-week period. Test-retest reliability for the BESTest (0.86) and mBEST (0.84) was good to excellent. MDC95 scores were identified for the BESTest (8.9) and mBEST (4). Conclusions: The BESTest and mBEST scores were stable and reliable over a period of 4 weeks for a population of older adults with self-reported balance problems or a history of falling. MDC95 scores allow interpretation of change in BESTest and mBEST scores following rehabilitation.
