Frailty and detection of fall risk are major issues in preventive gerontology. A simple tool frequently used in daily life, a bathroom scale (balance quality tester: BQT), was modified to obtain information on the balance of 84 outpatients consulting at a geriatric clinic. The results computed from the BQT were compared to the values of three geriatric tests that are widely used either to detect a fall risk or frailty (timed get up and go: TUG; 10 m walking speed: WS; walking time: WT; one-leg stand: OS). The BQT calculates four parameters that are then scored and weighted, thus creating an overall indicator of balance quality. Raw data, partial scores and the global score were compared with the results of the three geriatric tests. The WT values had the highest correlation with BQT raw data (r = 0.55), while TUG (r = 0.53) and WS (r = 0.56) had the highest correlation with BQT partial scores. ROC curves for OS cut-off values (4 and 5 s) were produced, with the best results obtained for a 5 s cut-off, both with the partial scores combined using Fisher's combination (specificity 85 %: <0.11, sensitivity 85 %: >0.48), and with the empirical score (specificity 85 %: <7, sensitivity 85 %: >8). A BQT empirical score of less than seven can detect fall risk in a community dwelling population.
衰弱和跌倒风险检测是老年预防医学中的主要问题。日常生活中常用的一种简单工具——体重秤（平衡质量测试仪：BQT），经过改良后用于获取在老年病诊所就诊的84名门诊患者的平衡信息。将BQT计算得出的结果与三种广泛用于检测跌倒风险或衰弱的老年测试值进行比较（定时起立行走测试：TUG；10米步行速度：WS；步行时间：WT；单腿站立：OS）。BQT计算四个参数，然后进行评分和加权，从而创建一个平衡质量的总体指标。将原始数据、部分得分和总体得分与三种老年测试的结果进行比较。WT值与BQT原始数据的相关性最高（r = 0.55），而TUG（r = 0.53）和WS（r = 0.56）与BQT部分得分的相关性最高。绘制了OS截止值（4秒和5秒）的ROC曲线，对于5秒的截止值，无论是使用Fisher组合法合并部分得分（特异性85%：<0.11，敏感性85%：>0.48）还是经验得分（特异性85%：<7，敏感性85%：>8），都获得了最佳结果。BQT经验得分低于7可以检测社区居住人群中的跌倒风险。
