Which functional tests on mobility and balance can better screen older people at risk of falls is unclear. This study aims to compare the Berg Balance Scale (BBS), Tinetti Mobility Score (TMS), Elderly Mobility Scale (EMS) and Timed Up and Go test (TUG) in discriminating fallers from non-fallers in older people.
This was a case-control study involving one rater who conducted a mobility and balance assessment on subjects using the four functional tests in random sequence. Subjects recruited included 17 and 22 older people with a history of single and multiple falls respectively from a public Falls Clinic, and 39 community-dwellers without fall history and whose age, sex and BMI matched those of the fallers. All subjects underwent the mobility and balance assessment within one day.
Single fallers performed better than multiple fallers in all four functional tests but were worse than non-fallers in the BBS, TMS and TUG. The BBS demonstrated the best discriminating ability, with high sensitivity and specificity. The BBS item 'pick up an object from the floor' was the best at screening fallers.
BBS was the most powerful functional test of the four in discriminating fallers from non-faller.
尚不清楚哪些关于活动能力和平衡能力的功能测试能更好地筛查有跌倒风险的老年人。本研究旨在比较伯格平衡量表（BBS）、蒂内蒂活动能力评分（TMS）、老年人活动量表（EMS）和计时起立行走测试（TUG）在区分老年人跌倒者与非跌倒者方面的效果。
这是一项病例对照研究，由一名评估者对受试者依次随机使用这四项功能测试进行活动能力和平衡能力评估。招募的受试者包括分别来自一家公共跌倒诊所的17名有单次跌倒史和22名有多次跌倒史的老年人，以及39名无跌倒史且年龄、性别和体重指数与跌倒者相匹配的社区居民。所有受试者在一天内接受了活动能力和平衡能力评估。
在所有四项功能测试中，单次跌倒者的表现均优于多次跌倒者，但在BBS、TMS和TUG测试中的表现比非跌倒者差。BBS表现出最佳的区分能力，具有较高的敏感性和特异性。BBS项目“从地板上捡起物品”在筛查跌倒者方面表现最佳。
在这四项功能测试中，BBS在区分跌倒者与非跌倒者方面最为有效。
