目的：利用Rasch分析来检验Berg平衡量表（BBS）的评定量表性能，并用功能术语描述45/56的分界点。设计：BBS评分回顾性图表回顾。对这些数据进行Rasch评定量表分析。单位：门诊退伍军人事务医疗中心。参与者：100名（99名男性，1名女性）因平衡性赤字而住在社区的退伍军人（年龄范围，64-88岁）。干预措施：不适用。主要评价指标：论坛。结果：压缩项目评定类别可以消除未充分利用的类别和构建的类别，更好地区分不同能力的人。为每个项目开发了评级枢轴点，以表示合格和不合格之间的过渡。随着支点开发和评分量表的评分，人和项目的测量在BBS上的分布更加均匀，导致项目难度顺序的变化。在我们的样本中，得分至少为45/56的功能指标是通过“串联站姿”项目的评分，以及通过以下3个项目中的2个：“交替脚”、“单腿站立”和“向后看”。结论：本研究结果为改进各项目的评定量表结构提供了指导，并建立了45/56的BBS分界点与功能能力之间的联系。
Objectives: To examine, using Rasch analysis, the rating scale performance of the Berg Balance Scale (BBS) and to describe the 45/56 cutoff score in functional terms.Design: Retrospective chart review of BBS scores. Rasch rating scale analysis was performed on these data.Setting: Outpatient Veterans Affairs medical center.Participants: One hundred (99 men, I woman) community-dwelling veterans referred for balance deficits (age range, 64-88y).Interventions: Not applicable.Main Outcome Measure: The BBS.Results: Condensing item-rating categories allowed the elimination of underutilized categories and constructed categories that better separated people of differing abilities. Rating pivot points were developed for each item to represent a transition between passing and failing. Following pivot-point development and rating scale rescoring, person and item measures became more evenly distributed across the BBS and resulted in changes in item difficulty order. In our sample, functional indicators of a score of at least 45/56 were a rating of passing the item "tandem stance," as well as passing 2 of the following 3 items: "alternating foot," "standing on one leg," and "look behind."Conclusions: Our findings provide direction for improving the rating scale structure for each of the items and establish a connection between the BBS cutoff score of 45/56 and functional ability.
