背景：平衡评估系统测试(BEST)是为了评估平衡控制的基本系统而开发的，以便能够为平衡障碍患者量身定制康复干预措施。开发了一种简短的形式，Mini-Best，作为一种筛查测试。本研究旨在评估挪威版BEST和MINI-BEST在有跌倒风险的社区人群中的评定者间和重测信度，并评估与国际跌倒效能量表(FES-I)的同时效度，这是一项横断面设计的观察性研究。方法：对42名跌倒风险增加的人(65岁以上的老年人、有中风或多发性硬化症病史的人)由两名评分员进行两次评估。用组内相关系数(ICC)分析相对可靠性，用标准测量误差(SEM)和最小可检测变化(SDC)分析绝对可靠性。结果：BEST具有很好的评分者间信度(ICC=0.98，SEM=1.79，SDC95=5.0)和重测信度(评分者A/评分者B=ICC=0.89/0.89，评分者SEM=3.9/4.3，SDC95=10.8/11.8)。Mini-Best具有很好的评分者间信度(ICC=0.95，SEM=1.19，SDC95=3.3)和重测信度(评分A/评分B=ICC=0.85/0.84，SEM=1.8/1.9，SDC95=4.9/5.2)。FES-I与BEST和MINI-BEST之间的相关性中等(Spearman‘s Rho’s Rho-0.51和-0.50，p<；0.01)。结论：BEST及其缩写Mini-Best在具有较高跌倒风险的不同样本中进行评估时，具有很好的评分员和重测可靠性。根据FES-I测量的同时效度显示出中等的相关性。这一结果与早期的研究具有可比性，表明挪威语版本可以用于日常临床和研究。
Background: The Balance Evaluation Systems Test (BESTest) was developed to assess underlying systems for balance control in order to be able to individually tailor rehabilitation interventions to people with balance disorders. A short form, the Mini-BESTest, was developed as a screening test. The study aimed to assess interrater and test-retest reliability of the Norwegian version of the BESTest and the Mini-BESTest in community-dwelling people with increased risk of falling and to assess concurrent validity with the Fall Efficacy Scale-International (FES-I), and it was an observational study with a cross-sectional design.Methods: Forty-two persons with increased risk of falling (elderly over 65 years of age, persons with a history of stroke or Multiple Sclerosis) were assessed twice by two raters. Relative reliability was analysed with Intraclass Correlation Coefficient (ICC), and absolute reliability with standard error of measurement (SEM) and smallest detectable change (SDC). Concurrent validity was assessed against the FES-I using Spearman's rho.Results: The BESTest showed very good interrater reliability (ICC = 0.98, SEM = 1.79, SDC95 = 5.0) and test-retest reliability (rater A/rater B = ICC = 0.89/0.89, SEM = 3.9/4.3, SDC95 = 10.8/11.8). The Mini-BESTest also showed very good interrater reliability (ICC = 0.95, SEM = 1.19, SDC95 = 3.3) and test-retest reliability (rater A/rater B = ICC = 0.85/ 0.84, SEM = 1.8/1.9, SDC95 = 4.9/5.2). The correlations were moderate between the FES-I and both the BESTest and the Mini-BESTest (Spearman's rho -0.51 and-0.50, p < 0.01).Conclusion: The BESTest and its short form, the Mini-BESTest, showed very good interrater and test-retest reliability when assessed in a heterogeneous sample of people with increased risk of falling. The concurrent validity measured against the FES-I showed moderate correlation. The results are comparable with earlier studies and indicate that the Norwegian versions can be used in daily clinic and in research.
