目的：评估 Berg 平衡量表 (BBS) 和单腿站立 (SLS) 的可重复性，以及 SLS 作为慢性卒中患者直立姿势控制的独立测试的有效性。设计：评估者内重测可重复性研究。 BBS 和 SLS 评估两次，相隔 7 天。地点：大学医院。参与者：50 人；中风后 6-46 个月。 主要结果测量：BBS 和 SLS 的再现性通过组内相关系数 (ICC2,1)、95% 置信区间 (95% Cl) 的 2 个测试会话之间的平均差异 ((d) over bar)、测量标准误差 (测量标准误差 [SEM]%)、最小实际差异 (SRD%) 和 Bland-Altman 图进行评估。为了评估SLS的有效性，通过Pearson相关系数分析SLS和BBS之间的关系。结果：BBS的ICC2,1值为0.88，SLS的非偏瘫肢体的ICC2,1值为0.88，偏瘫下肢的ICC2,1值为0.92。表明一组个体真正改善的最小变化（SEM%）对于 SLS 来说，BBS 为 3%，非麻痹肢体为 15%，麻痹肢体为 27%。对于单个个体而言，BBS 的最小实际差异为 8%，但 SLS 的实际差异更高，非麻痹肢体为 42%，麻痹肢体为 74%。 SLS 和 BBS 之间存在显着相关性 (r = 0.65-0.79；P < .001)。 结论：BBS 和 SLS 是慢性卒中患者的可重复测量值，但只有 BBS 足够灵敏，能够跟踪随时间推移或干预后的变化。 SLS 与 BBS 密切相关，可用作测量中风后直立姿势控制的独立测试。 PM R 2012；4:165-170
Objective: To assess the reproducibility of the Berg Balance Scale (BBS) and the Single-leg Stance (SLS), and the validity of the SLS as an independent test of upright postural control in patients with chronic stroke.Design: An intra-rater test-retest reproducibility study. The BBS and the SLS were assessed twice, 7 days apart.Setting: A university hospital.Participants: Fifty individuals; 6-46 months after a stroke.Main Outcome Measurements: The reproducibility of the BBS and the SLS was evaluated with intraclass correlation coefficient (ICC2,1), the mean difference between the 2 test sessions ((d) over bar) with 95% confidence interval (95% Cl), the standard error of measurement (standard error of measurement [SEM]%), the smallest real difference (SRD%), and the Bland-Altman graphs. To assess validity of SLS, the relationship between the SLS and the BBS was analyzed by the Pearson correlation coefficient.Results: The ICC2,1 was 0.88 for the BBS, and the ICC2,1 values were 0.88 for the nonparetic limb and 0.92 for the paretic lower limb for the SLS. The smallest change that indicates a real improvement for a group of individuals, SEM%, was 3% for BBS, 15% for the nonparetic limb and 27% for the paretic limb for SLS. The smallest real difference for a single individual was 8% for BBS but was higher for SLS, at 42% for the nonparetic limb, and 74% for the paretic limb. There was a significant relationship between the SLS and the BBS (r = 0.65-0.79; P < .001).Conclusions: The BBS and the SLS are reproducible measurements in patients with chronic stroke, but only the BBS is sensitive enough to follow changes over time or after an intervention. The SLS is strongly related to the BBS and can be used as an independent test to measure upright postural control after a stroke. PM R 2012;4:165-170
