产品名称：设计：横断面重复测量研究。设置：研究诊所。参与者：以人口为基础的样本，年龄在35至55岁和56至71岁的日裔美国人没有明显的功能障碍（N = 203）。测量：身体功能的基于性能的测量，包括一系列标准测试，平衡和力量的更新自动化测量以及认知功能，生活方式，病史和身体活动的数据。在非平台平衡测量中，只有单腿站立是可靠的（可靠性系数（rc）= 0.69），并且能够区分功能水平。将第四次全国健康与营养检查调查协议（即站在泡沫垫上时双臂交叉的姿势）与更复杂的平衡平台测试相结合，具有最高的可靠性和区分度。使用强度椅，上肢和下肢测试的rcs较高（0.88-0.96）。计时椅立、下肢肌力和中心力量测试结果可靠。6分钟步行有较高的rc（0.90）。结论：目前使用的许多性能测试是不可靠的。只有少数人区分最高功能的个体和具有良好功能的个体。因此，一个新的推荐电池包括无辅助单腿站立，平衡平台“泡沫垫，闭上眼睛”，肘关节弯曲和膝关节伸展力量（力量椅），握力，定时椅站，和6分钟的步行。这些简单的基于性能的测试在功能范围内具有良好的可靠性和区分度，可用于大多数临床和研究环境，以快速评估整体功能水平。
OBJECTIVES:: To improve and broaden the applicability of performance-based measures of function for use in clinical and research settings.DESIGN: Cross-sectional repeated-measures study.SETTING: Research clinic.PARTICIPANTS: Population-based sample of Japanese Americans without significant functional impairments aged 35 to 55 and 56 to 71 (N = 203).MEASUREMENTS: Performance-based measures of physical function, including range of standard tests, newer automated measures of balance and strength and data on cognitive function, lifestyle, medical history, and physical activity.RESULTS: Of the nonplatform balance measures, only the one-leg stand was reliable (reliability coefficient (rc) = 0.69) and able to discriminate between functional levels. Combining the Fourth National Health and Nutrition Examination Survey protocol of folded arm position while standing on a foam pad with the more-sophisticated balance platform test had the highest reliability and discrimination. With the strength chair, high rcs (0.88-0.96) were found for upper and lower extremity tests. Timed chair stands, a test of lower extremity and central strength were reliable. The 6-minute walk had a high rc (0.90).CONCLUSION: Many performance tests used today are not reliable. Only a few discriminate between the most highly functioning individuals and individuals with good function. Thus, a new recommended battery includes unassisted single-leg stand, balance platform "foam pad, eyes closed," elbow flexion and knee extension strength (strength chair), grip strength, timed chair stands, and the 6-minute walk. These simple performance-based tests have good reliability and discrimination across the range of function and can be used in most clinical and research settings to quickly assess global functional level.
