目的：应用动态姿势描记术测量健康老年人的平衡变化。这些变化与临床措施的平衡和gait.Design：老年受试者筛选健康标准的纵向研究进行了检查，使用标准化的认知，神经，和性能为基础的测试。定量姿势描记术（Equitest，Neurocom International，Clackamas，Ore）来确定受试者对感觉刺激的反应。（感觉组织测试）和运动扰动受试者：33名健康老年受试者（大于或等于80岁;平均+/- SD年龄，88 +/- 5岁）与15例年龄小于80岁的受试者（平均+/- SD年龄，72 +/- 3岁）进行比较。所有人都没有中枢活性药物。结果：老年人有更差的定量平衡分数与受试者年轻，80岁时本体感觉输入是不准确的，视觉输入是保存或完全不存在。老年受试者表现出对重复平台旋转的适应性减弱，并且在姿势描记过程中跌倒更频繁。定量平衡措施与年龄和功能措施的平衡（Tinetti平衡量表评分，定时1腿站立）。结论：渐进的，功能明显，年龄相关的定量平衡变化发生独立的典型老年病理变化。这些数据应有助于临床决策，使年龄相关的和病理变化之间的区别。
Objectives: To measure balance changes in the healthy elderly using quantitative dynamic posturography. To relate these changes to clinical measures of balance and gait.Design: Elderly subjects screened for health criteria in a longitudinal study were examined using standardized cognitive, neurological, and performance-based tests. Quantitative posturography (Equitest, Neurocom International, Clackamas, Ore) was performed to determine the subject's response to sensory (Sensory Organization Test) and motor perturbations (Motor Coordination Test).Subjects: Thirty-three healthy, old old subjects (greater than or equal to 80 years; mean +/- SD age, 88 +/- 5 years) were compared with 15 subjects younger than 80 years (mean +/- SD age, 72 +/- 3 years). All were free of centrally active medications.Results: The old old had worse quantitative equilibrium scores compared with subjects younger that 80 years when proprioceptive input was inaccurate and visual input was either preserved or completely absent. Old old subjects showed diminished adaptation to repeated platform rotations and fell more frequently during posturography. Quantitative balance measures correlated with age and functional measures of balance (Tinetti Balance Scale score, timed 1 leg standing).Conclusions: Progressive, functionally evident, age-related quantitative balance changes occur independent of typical geriatric pathological changes. These data should facilitate clinical decisions by allowing the distinction to be made between age-related and pathological changes.
