[Purpose] This study was aimed to determine the relative and absolute reliability of Korean version tools of the Berg Balance Scale (BBS), the Timed Up and Go (TUG), the Four-Meter Walking Test (4MWT) and the Groningen Meander Walking Test (GMWT) in patients with dementia. [Subjects and Methods] A total of 53 patients with dementia were tested on TUG, BBS, 4MWT and GMWT with a prospective cohort methodological design. Intra-class Correlation Coefficients (ICCs) to assess relative reliability and the standard error of measurement (SEM), minimal detectable change (MDC) and its percentage (MDC) to analyze the absolute reliability were calculated. [Results] Inter-rater reliability (ICC) of TUG, BBS and GMWT was 0.99 and that of 4MWT was 0.82. Inter-rater reliability was high for TUG, BBS and GMWT, with low SEM, MDC, and MDC. Inter-rater reliability was low for 4MWT, with high SEM, MDC, and MDC. Test-retest (ICC) of TUG, BBS and GMWT was 0.96-0.99 and Test-retest (ICC) of 4MWT was 0.85. The test-retest was high for TUG, BBS and GMWT, with low SEM, MDC, and MDC, but it was low for 4MWT, with high SEM, MDC, and MDC. [Conclusion] The relative reliability was high for all the assessment tools. The absolute reliability has a reasonable level of stability except the 4MWT.
[目的] 本研究旨在确定韩国版伯格平衡量表（BBS）、定时起立行走测试（TUG）、四米步行测试（4MWT）和格罗宁根蜿蜒步行测试（GMWT）在痴呆患者中的相对可靠性和绝对可靠性。[对象与方法] 采用前瞻性队列研究方法，对53例痴呆患者进行TUG、BBS、4MWT和GMWT测试。计算用于评估相对可靠性的组内相关系数（ICC）以及用于分析绝对可靠性的测量标准误差（SEM）、最小可检测变化（MDC）及其百分比（MDC%）。[结果] TUG、BBS和GMWT的评分者间信度（ICC）为0.99，4MWT的评分者间信度为0.82。TUG、BBS和GMWT的评分者间信度较高，SEM、MDC和MDC%较低。4MWT的评分者间信度较低，SEM、MDC和MDC%较高。TUG、BBS和GMWT的重测信度（ICC）为0.96 - 0.99，4MWT的重测信度（ICC）为0.85。TUG、BBS和GMWT的重测信度较高，SEM、MDC和MDC%较低，但4MWT的重测信度较低，SEM、MDC和MDC%较高。[结论] 所有评估工具的相对可靠性较高。除4MWT外，绝对可靠性具有合理的稳定性水平。
