目的：探讨功能伸展试验与压力中心位移的相关性，以及该试验是否可作为健康老年人稳定性极限的测量指标。并探讨了功能到达测试期间的性能参数。设计：方法比较研究。对象：健康老年人27例。方法：采用全身运动学（ELITE系统）、地面反作用力（AMTI）和肌肉活动（EMG）与临床尺度测量平行，同时进行功能伸展试验。结果：到达距离与压力中心位移的相关性较低（r=0.38），躯干前倾与到达距离的相关性中等（r=0.68）。在功能伸展测试中，运动的特点是躯干大的向前旋转和脚踝的小伸展。后者约束压力中心正向位移。结论：结果表明，功能延伸试验是稳定性极限的弱测量。树干的运动似乎比压力中心的位移对测试的影响更大。当使用功能延伸测试来评估平衡时，应考虑到补偿机制。
Objective: To explore how the Functional Reach test correlates with the displacement of the centre of pressure and whether the test is a measure of the stability limits in healthy elderly people. Also to explore the performance parameters during the Functional Reach test.Design: Method comparison study.Subjects: Twenty-seven healthy elderly subjects.Methods: Whole body kinematics (ELITE systems), ground reaction forces (AMTI) and muscle activity (EMG) parallel with clinical yardstick measure while performing the Functional Reach test.Results: This study showed a low correlation (r=0.38) between reach distance and displacement of centre of pressure and a moderate correlation (r=0.68) between forward rotation of the trunk and reach distance. The movement during the Functional Reach test was characterized by a large forward rotation of the trunk and a small extension in the ankle. The latter constraining centre of pressure forward displacement.Conclusions: The results suggest that the Functional Reach test is a weak measure of the stability limits. Movement of the trunk seems to influence the test more than the displacement of the centre of pressure. When using the Functional Reach test for assessing balance, compensatory mechanisms should be taken into account.
