目的：对社区居住卒中幸存者的再发跌倒风险量表（ReFR）进行外部验证。方法：从参考门诊卒中诊所招募具有独立步态能力的卒中幸存者队列。除社会人口学和临床资料外，采用以下量表：修正Barthel指数（mBI）、ReFR量表和美国国立卫生研究院卒中量表（NIHSS）。研究人员对参与者进行了12个月的随访，记录他们跌倒的情况。以ROC曲线下面积衡量ReFR量表的准确性。结果：在2016年4月至2016年11月期间招募了113人：平均年龄54岁（±14岁），55%为女性，自上次中风以来的中位时间为24个月（范围12 -48个月），35%的样本后侧血管区域受到影响。NIHSS中位数为3（范围1 - 6），mBI中位数为49（范围46-50），ReFR中位数为3（范围2 -5）。在随访期间，32名（33%）受试者至少有一次跌倒，18名（19%）是复发性跌倒（两次或两次以上）。ReFR量表的准确度为0.67 (95% CI = 0.54 ~ 0.79), p = 0.026。结论：本研究从外部验证了ReFR作为预测中风后个体复发性跌倒的工具。(c) 2020 Elsevier Inc.版权所有。
Objective: To externally validate the Recurrent Fall Risk Scale (ReFR) in community-dwelling stroke survivors. Methods: Cohort of stroke survivors with independent gait ability recruited from a reference outpatient stroke clinic. Besides sociodemographic and clinical data, the following scales were used: Modified Barthel Index (mBI), ReFR scale and National Institutes of Health Stroke Scale (NIHSS). Participants were followed up for 12 months to record the incidence of falls. Accuracy of the ReFR scale was measured by the area under the ROC curve. Results: One hundred and thirteen individuals were recruited between April 2016 and November 2016: mean age 54 years (+/- 14), 55% women, median time since the last stroke 24 months (range 12 -48 months), posterior vascular territory affected in 35% of the sample. Median NIHSS was 3 (range 1 to 6), median mBI 49 (range 46-50), median ReFR 3 (range 2 to 5). During the follow-up period, 32 (33%) subjects had at least one fall and 18 (19%) were recurrent fallers (two or more falls). The accuracy of ReFR scale was 0.67 (95% CI = 0.54-0.79), p = 0.026. Conclusion: This study externally validated the ReFR as a tool to predict recurrent falls in individuals after stroke. (c) 2020 Elsevier Inc. All rights reserved.
