The study aim was to examine the responsiveness of the Berg Balance Scale (BBS) and that of its short form (SFBBS) at both the individual person level and the group level.
A repeated-measurements design.
Hospital and home setting.
Patients with stroke.
Totals of 226, 202, and 168 patients with stroke were assessed with the BBS at 14, 30, and 90 days after stroke, respectively. The SFBBS data were extracted from the patients' responses on the BBS. At the group level, the BBS and the SFBBS had sufficient and similar responsiveness. For the Rasch scores, the effect sizes of the three change scores for the BBS and the SFBBS, respectively, had similar ranges between 0.38 and 0.88 and between 0.39 and 0.85, respectively. The standardized response means of the three change scores for the BBS and the SFBBS ranged from 0.74 to 1.33 and from 0.72 to 1.13, respectively. At the individual person level, the BBS detected significant balance improvement in about twice as many patients as the SFBBS detected.
The responsiveness of the BBS at the individual person level was better than that of the SFBBS in patients with stroke. The BBS is recommended as an outcome measure to better detect changes in individual patients.
本研究旨在检验伯格平衡量表（BBS）及其简表（SFBBS）在个体水平和群体水平上的反应性。

中风患者。
分别在中风后14天、30天和90天，共有226例、202例和168例中风患者接受了BBS评估。SFBBS数据从患者对BBS的回答中提取。在群体水平上，BBS和SFBBS具有充分且相似的反应性。对于拉施分数，BBS和SFBBS的三个变化分数的效应量分别在0.38至0.88和0.39至0.85的相似范围内。BBS和SFBBS的三个变化分数的标准化反应均值分别为0.74至1.33和0.72至1.13。在个体水平上，BBS检测到平衡有显著改善的患者数量约为SFBBS检测到的两倍。
在中风患者中，BBS在个体水平上的反应性优于SFBBS。推荐使用BBS作为结局指标，以更好地检测个体患者的变化。
