The aim of this study is to determine the test-retest reproducibility of the seven-item Short-Form Berg Balance Scale (SFBBS) and the five-item Short-Form Postural Assessment Scale for Stroke Patients (SFPASS) in individuals with chronic stroke. Fifty-two chronic stroke patients from two rehabilitation departments were included in the study. Both balance measures were administered twice 7 days apart. Test-retest reliability was analysed using the weighted κ (κ(w)) statistic for each item and intraclass correlation coefficients (ICC(2,1)) for the total scores of both measures. Agreement was expressed as the SEM, minimal detectable change and limits of agreement by Bland and Altman analysis. Test-retest agreements were good to very good for SFBBS and SFPASS, with weighted κ values ranging from 0.75 to 0.89 and 0.66 to 0.84, respectively. The ICCs for the total SFBBS and SFPASS scores were excellent (ICC(2,1): SFBBS=0.99; SFPASS=0.93). The SEMs for both measures were less than 10% of the score range; the minimal detectable changes of the SFBBS and SFPASS were 2.83 and 2.16, respectively, indicating that both measures had a small and acceptable measurement error. Both measures showed good reproducibility. These results indicate that the SFBBS and SFPASS are useful for clinicians and researchers for the evaluation of balance performance and to determine whether the change score of an individual with stroke is real.
本研究旨在确定七项简短版伯格平衡量表（SFBBS）和五项中风患者简短版姿势评估量表（SFPASS）在慢性中风患者中的重测信度。来自两个康复科室的52例慢性中风患者纳入本研究。两种平衡测量方法均在相隔7天的时间内进行两次测量。使用加权κ（κ(w)）统计量分析每个项目的重测信度，并使用组内相关系数（ICC(2,1)）分析两种测量方法总分的重测信度。通过Bland和Altman分析，以标准误（SEM）、最小可检测变化和一致性界限表示一致性。SFBBS和SFPASS的重测一致性良好至极优，加权κ值分别为0.75至0.89和0.66至0.84。SFBBS和SFPASS总分的ICC均为优秀（ICC(2,1)：SFBBS = 0.99；SFPASS = 0.93）。两种测量方法的SEM均小于评分范围的10%；SFBBS和SFPASS的最小可检测变化分别为2.83和2.16，表明两种测量方法的测量误差小且可接受。两种测量方法均显示出良好的重测信度。这些结果表明，SFBBS和SFPASS对临床医生和研究人员评估平衡功能以及确定中风患者的变化分数是否真实有用。
