Four common tests of balance and mobility were administered to 45 healthy women, aged 55-71 years: Sharpened Romberg (also defined as tandem stance), eyes open and closed; One-Legged Stance Test, eyes open and closed; Functional Reach; and Sit-To-Stand test. Two independent observers scored the tests, which were performed on two successive days. Inter-rater (IRR) and test-retest reliability (TRR) were good. Across the six different tests, Intraclass Correlation Coefficients ranged from 0.95 to 0.99 for scoring consistency between rates, and from 0.73 to 0.93 within raters. This is in line with previous findings based on similar subjects and similar, though not identical, testing procedures. Intercorrelations between the scores were moderate: r coefficients ranged 0.40-0.66. The results suggest that this simple test battery provides reliable scores, and that the different tests relate to a homogeneous construct, while not being redundant. It thus seems worthwhile to further investigate whether they represent and measure a unidimensional domain, rather than conceptually different dimensions, in view of achieving a unique measure of balance performance.
对45名年龄在55至71岁之间的健康女性进行了四项常见的平衡和活动能力测试：睁眼和闭眼的改良罗姆伯格试验（也称为串联站立）；睁眼和闭眼的单腿站立试验；功能性伸展试验；以及从坐到站试验。由两名独立观察员对测试进行评分，测试在连续两天进行。评分者间信度（IRR）和重测信度（TRR）良好。在这六项不同的测试中，组内相关系数在评分者之间的评分一致性方面为0.95至0.99，在评分者内部为0.73至0.93。这与之前基于类似受试者和类似（虽不完全相同）测试程序的研究结果一致。分数之间的相互关联程度适中：r系数范围为0.40 - 0.66。结果表明，这个简单的测试组合能提供可靠的分数，并且不同的测试与一个同质的结构相关，同时又并非冗余。因此，鉴于要实现对平衡能力的独特测量，进一步研究这些测试是否代表和测量的是一个单维领域而非概念上不同的维度似乎是值得的。
