背景。对来自三个社区的5000多名71岁及以上的老年人进行了一系列简短的体能测试，以评估他们的下肢功能。平衡、步态、力量和耐力通过检查两脚并拢站立、半串联和串联姿势的能力、行走8英尺的时间、从椅子上站起来并回到坐姿的时间5次来评估。每个测试的性能分布都很广。每个测试和总结表现量表，通过汇总每个测试的表现分类排名而产生，与残疾的自我报告密切相关。在多变量分析中，自我报告项目和绩效测试都是短期死亡率和疗养院入院的独立预测因子。然而，有证据表明，绩效测试提供了自我报告项目无法提供的信息。特别重要的是，研究发现，在那些处于功能谱系高端、几乎没有残疾的人身上，表现测试分数区分出了死亡率和疗养院入院风险的梯度。此外，在具有相同自我报告概况的亚组中，存在与年龄和性别相关的身体表现的系统性差异。这项研究提供的证据表明，性能测量可以有效地表征老年人在广泛的下肢功能。在提供有关功能状态的有用信息方面，绩效和自我报告度量可以相互补充。
Background. A short battery of physical performance tests was used to assess lower extremity function in more than 5,000 persons age 71 years and older in three communities.Methods. Balance, gait, strength, and endurance were evaluated by examining ability to stand with the feet together in the side-by-side, semi-tandem, and tandem positions, time to walk 8 feet, and time to rise from a chair and return to the seated position 5 times.Results. A wide distribution of performance was observed for each test. Each test and a summary performance scale, created by summing categorical rankings of performance on each test, were strongly associated with self-report of disability. Both self-report items and performance tests were independent predictors of short-term mortality and nursing home admission in multivariate analyses. However, evidence is presented that the performance tests provide information not available from self-report items. Of particular importance is the finding that in those at the high end of the functional spectrum, who reported almost no disability, the performance test Scores distinguished a gradient of risk for mortality and nursing home admission. Additionally, within subgroups with identical self-report profiles, there were systematic differences in physical performance related to age and sex.Conclusion. This study provides evidence that performance measures can validly characterize older persons across a broad spectrum of lower extremity function. Performance and self-report measures may complement each other in providing useful information about functional status.
