目的：建立我们的新的平衡工具，功能伸展(FR=最大安全站立前伸)，作为身体虚弱的标志与其他临床体能表现指标的同时效度。设计、设置和参与者：使用(1)FR(标尺方法)，(2)日常生活的体力和工具活动(PADL，IADL)，(3)生活空间，3点社会流动性的测量，(4)10项分级行动技能协议，(5)10英尺步行速度，在一个时间点上评估了45名66-104岁的社区居民。(6)单脚站立；(7)串联行走。数据分析采用了斯皮尔曼相关性。结果：FR表现范围较宽(4.3~16.5英寸，平均10.9英寸，SD 3.1)。除PADL外，FR与其他体能指标的相关性较强，相关系数为0.64~0.71，与PADL的相关性为0.48。在回归分析中控制年龄后，偏相关系数在0.52-0.63之间。FR与年龄的相关系数为-0.50。结论：根据横断面数据，FR是一种实用的测量工具，其与身体虚弱的相关性甚至大于与年龄的相关性。
Objective: To establish the concurrent validity of our new balance instrument, functional reach (FR = maximal safe standing forward reach), as a marker of physical frailty compared with other clinical measures of physical performance.Design, Setting, and Participants: 45 community-dwelling persons age 66-104 were evaluated at one point in time using (1) FR (yardstick method), (2) Physical and Instrumental Activities of Daily Living (PADL, IADL), (3) Life Space, a 3-point measure of social mobility, (4) 10-item hierarchical mobility skills protocol, (5) 10-foot walking speed, (6) one-footed standing, and (7) tandem walking. Data analysis employed Spearman correlations. Partial r's were also calculated after controlling for age.Results: The FR performance range was broad (4.3-16.5 inches, mean 10.9, SD 3.1). Except for PADL, the association of FR with the other physical performance measures was strong, with r's ranging from 0.64-0.71; the association of FR with PADL was 0.48. After controlling for age in the regression analysis, partial r's ranged from 0.52-0.63. The association of FR with age was -0.50.Conclusions: Based on cross-sectional data, FR is a practical instrument that correlates with physical frailty even more than with age.
