目的：为了确定是否电池的13 sensorimotor，前庭，和视觉测试区分老年人跌倒和老年nonfallers.Design：为期一年的前瞻性研究。设置：在一个124张床位的宿舍老年人，在悉尼，澳大利亚。参与者：95人年龄在59和97岁（平均年龄82.7岁）参加了这项研究。 在29名非参与者中，4人生病，5人缺席（假期等），20人谢绝。 居民一般独立的日常生活活动，虽然个人护理assistance.Results：84名参与者可供跟进。 在随访的一年中，40名受试者没有发生福尔斯，11名受试者仅跌倒一次，33名居民跌倒两次或两次以上。 总共有145次福尔斯。 判别函数分析确定了下肢本体感觉、视觉对比敏感度、踝关节背屈强度、反应时间和闭眼摇摆作为变量，这些变量显著区分了经历多次福尔斯跌倒的受试者和没有经历福尔斯跌倒或仅经历一次跌倒的受试者。 该程序正确地将79%的受试者分为多个跌倒者或非多个跌倒者组。 与非跌倒者和仅一次跌倒者相比，多次跌倒者的股四头肌力量较差，但差异无统计学意义。 有一个小的差异，在非瀑布，一次只有瀑布，和多个fallers.Conclusion测试前庭功能的平均分数：看来，这种方法突出了一些关键的生理因素，易患老年人福尔斯。
Objective: To determine whether a battery of 13 sensorimotor, vestibular, and visual tests discriminates between elderly fallers and elderly non-fallers.Design: One-year prospective study.Setting: Conducted at a 124-bed Hostel for Aged Persons, in Sydney, Australia.Participants: Ninety-five persons aged between 59 and 97 years (mean age 82.7 years) took part in the study. Of the 29 non-participants, four were ill, five were absent (on holidays, etc), and 20 declined. Residents were generally independent in activities of daily living although personal care assistance was available.Results: Eighty-four participants were available for follow-up. In the follow-up year, 40 subjects experienced no falls, 11 subjects fell one time only, 33 residents fell on two or more occasions. There was a total of 145 falls. Discriminant function analysis identified proprioception in the lower limbs, visual contrast sensitivity, ankle dorsiflexion strength, reaction time, and sway with the eyes closed as the variables that significantly discriminated between subjects who experienced multiple falls and subjects who experienced no falls or one fall only. This procedure correctly classified 79% of subjects into multiple faller or non-multiple faller groups. Quadriceps strength was poorer in the multiple fallers compared with the non-fallers and once-only fallers, although the difference was not statistically significant. There was little difference in the mean scores for the tests of vestibular function in the non-fallers, once-only fallers, and multiple fallers.Conclusion: It appears that this approach highlights some key physiological factors that predispose elderly individuals to falls.
