一种新的临床上可获得的平衡测量方法，功能性伸展（FR），是使用固定的支撑底座时臂长和最大向前伸展之间的差异。 本研究的目的是：（a）将FR确定为相对于实验室测量值（压力偏移中心（科普））的稳定裕度的测量值;（B）测试可靠性和精密度;（c）确定影响FR的因素，包括年龄和人体测量学。 我们评估了128名志愿者（年龄21-87岁）的FR。 用精密的电子设备和简单的临床仪器（标尺）测定FR。 FR与科普相关（Pearson r = 0.71），具有精确性（变异系数= 2.5%）和稳定性（不同天数的组内相关系数= 0.81）。 年龄和身高影响FR。FR是便携式的，廉价的，可靠的，精确的，和一个合理的临床近似的稳定性的边缘。 FR可能是有用的检测平衡障碍，随着时间的推移，在平衡性能的变化，并在受损的老年人的修改环境的设计。
A new clinically accessible measure of balance, functional reach (FR), is the difference between arm's lenght and maximal forward reach, using a fixed base of support. The purposes of this study were to (a) establish FR as a measure of the margin of stability versus the laboratory measure, center of pressure excursion (COPE); (b) test reliability and precision, and (c) determine factors that influence FR, including age and anthropometrics. We evaluated FR in 128 volunteers (age 21-87 years). FR was determined with a precise electronic device and a simple clinical apparatus (yardstick). FR correlates with COPE (Pearson r = .71) and is precise (coefficient of variation = 2.5%) and stable (intraclass correlation coefficient across days = .81). Age and height influence FR. FR is portable, inexpensive, reliable, precise, and a reasonable clinical approximator of the margin of stability. FR may be useful for detecting balance impairment, change in balance performance over time, and in the design of modified enviroments for impaired older persons.
