目的：确定社区居住的65岁及以上女性人群中视力、外周感觉、下肢肌力、反应时间和平衡受损的患病率，并确定这些测试中的受损表现是否与福尔斯相关。产品设计：一年前瞻性研究。设置：作为Randwick福尔斯和骨折研究的一部分，在悉尼，Australia.Participants：414名年龄在65至99岁（平均年龄73.7岁，SD = 6.3）的妇女被随机选择从社区; 341这些妇女被纳入1年前瞻性研究。在评估后一年，207例受试者（60.7%）未发生福尔斯，63例受试者（18.5%）仅跌倒一次，71例受试者（20.8%）跌倒两次或两次以上。在控制年龄后，多次跌倒与低对比度视力和对比敏感度、振动感和本体感觉差、下肢力量降低、反应时间慢和平衡受损相关，如四次摇摆试验和两次临床稳定性测量所示。判别函数分析确定了视觉对比敏感度，下肢本体感觉，股四头肌力量，反应时间和摇摆在一个顺从的（泡沫橡胶）表面与眼睛睁开作为变量，显著区分受试者经历多次福尔斯和受试者没有经历福尔斯或只有一次跌倒（Wilks λ = 0.73（P < 0.001），典型相关= 0.52）。这个程序正确分类75%的科目到多个瀑布或nonmultiple瀑布groups.CONCLUSIONS：这些研究结果支持以前的结果进行退休村和机构设置，并表明，测试程序艾滋病在识别老年社区居住的妇女在福尔斯的风险。
OBJECTIVE: To determine the prevalence of impaired vision, peripheral sensation, lower limb muscle strength, reaction time, and balance in a large community-dwelling population of women aged 65 years and over, and to determine whether impaired performances in these tests are associated with falls. DESIGN: One-year prospective study.SETTING: Conducted as part of the Randwick Falls and Fractures Study, in Sydney, Australia.PARTICIPANTS: Four hundred fourteen women aged 65 to 99 years (mean age 73.7 years, SD = 6.3) were randomly selected from the community; 341 of these women were included in the 1-year prospective study.MAIN RESULTS: The prevalence of impairment in all tests increased with age. In the year following assessment, 207 subjects (60.7%) experienced no falls, 63 subjects (18.5%) fell one time only, and 71 subjects (20.8%) fell on two or more occasions. After controlling for age, multiple falling was associated with low contrast visual acuity and contrast sensitivity, poor vibration sense and proprioception, reduced lower limb strength, slow reaction time, and impaired balance, as indicated by four sway tests and two clinical stability measures. Discriminant function analysis identified visual contrast sensitivity, proprioception in the lower limbs, quadriceps strength, reaction time, and sway on a compliant (foam rubber) surface with the eyes open as the variables that significantly discriminated between subjects who experienced multiple falls and subjects who experienced no falls or one fall only (Wilks' lambda = 0.73 (P < 0.001), canonical correlation = 0.52). This procedure correctly classified 75% of subjects into multiple faller or nonmultiple faller groups.CONCLUSIONS: These findings support previous results conducted in retirement village and institutional settings and indicate that the test procedure aids in the identification of older community-dwelling women at risk of falls.
