To externally validate the Recurrent Fall Risk Scale (ReFR) in community-dwelling stroke survivors.
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.
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.
This study externally validated the ReFR as a tool to predict recurrent falls in individuals after stroke.
验证社区居住的中风幸存者复发性跌倒风险量表（ReFR）的外部有效性。
从参考门诊中风诊所招募具有独立步行能力的中风幸存者队列。除了社会人口统计学和临床数据外，还使用了以下量表：改良巴氏指数（mBI）、ReFR 量表和美国国立卫生研究院中风量表（NIHSS）。对参与者进行了 12 个月的随访，以记录跌倒的发生率。ReFR 量表的准确性通过 ROC 曲线下面积来衡量。
2016 年 4 月至 2016 年 11 月期间共招募了 113 名个体：平均年龄 54 岁（±14），55%为女性，最近一次中风后中位数时间为 24 个月（范围 12-48 个月），样本中有 35%的后循环血管区域受累。中位数 NIHSS 为 3（范围 1 至 6），中位数 mBI 为 49（范围 46-50），中位数 ReFR 为 3（范围 2 至 5）。在随访期间，32 名（33%）受试者至少发生了一次跌倒，18 名（19%）是复发性跌倒者（两次或更多次跌倒）。ReFR 量表的准确性为 0.67（95%CI=0.54-0.79），p=0.026。
本研究验证了 ReFR 作为预测中风后个体复发性跌倒的工具的外部有效性。
