recurrent fallers are at especially high risk for injuries.
to study whether tests of physical performance are associated with recurrent falls.
a total of 10,998 men aged 65 years or above.
questionnaires evaluated falls sustained 12 months preceding testing of grip strength, timed stand, 6-m walk and 20-cm narrow walk test. Means with 95% confidence interval (95% CI) are reported. P < 0.01 is a statistically significant difference.
in comparison to both occasional fallers and non-fallers, recurrent fallers performed more poorly on all the physical ability tests (all P < 0.001). A score below -2 standard deviations (SDs) in the right-hand grip strength test was associated with an odds ratio of 2.4 (95% CI 1.7, 3.4) for having had recurrent falls compared with having had no fall and of 2.0 (95% CI 1.3, 3.4) for having had recurrent falls compared with having had an occasional fall.
low performance in physical ability tests are in elderly men associated with recurrent falls.
反复跌倒者受伤的风险特别高。
研究身体机能测试是否与反复跌倒有关。
共有 10998 名年龄在 65 岁及以上的男性。
使用问卷评估在进行握力、定时站立、6 米步行和 20 厘米狭窄步行测试前 12 个月内发生的跌倒情况。报告均数及其 95%置信区间（95%CI）。P<0.01 为统计学显著差异。
与偶发性跌倒者和非跌倒者相比，反复跌倒者在所有身体能力测试中表现更差（均 P<0.001）。右手握力测试得分低于-2 个标准差（SD）与反复跌倒的比值比（OR）为 2.4（95%CI 1.7, 3.4），与无跌倒相比，与偶发性跌倒相比 OR 为 2.0（95%CI 1.3, 3.4）。
老年人身体机能测试表现较差与反复跌倒有关。
