目的：研究姿势摇摆与感觉运动障碍、功能表现和自我报告的残疾之间的关系。设计：横断面队列。设置：退伍军人事务部医疗中心。患者：100名无法一步一步爬楼梯的社区居住老年人。主要结果测量：重心动摇（椭圆面积和路径长度，眼睛睁开和闭上），感觉运动（力量、感觉、活动范围、中央处理时间）、功能表现（功能性伸展、定时步态、移动技能、耐力）和残疾（MOS-SF 36，福尔斯功效量表[FES]）。结果：姿势摇摆面积测量与感觉运动测量相关：（1）在闭眼条件下，感觉缺陷个体的摇摆增加（p <0.05）;（2）摇摆与胫骨前肌潜伏期呈正相关（p <0.05）;（3）摇摆面积随力量增加而增加（p <0.05）。摇摆/强度关系可以解释为虚弱的受试者通过限制而不是增加摇摆来改善其稳定性。摇摆与任何身体表现指标都没有显著相关性。摇摆与某些残疾指标相关：（1）闭眼姿势摇摆指标与FES评分相关（p <0.05）;（2）摇摆与MOS-36身体功能问题无关。当控制的功能措施，闭眼措施摇摆显着预测FES分数（p <0.03）。结论：措施的姿势摇摆更可能捕捉感觉运动缺陷，而不是区分功能的性能能力，姿势摇摆和自我报告的残疾之间的关系是不一致的。(C)1996年由美国康复医学大会和美国物理医学与康复学会
Objective: To examine the relationship of postural sway to sensorimotor impairment, functional performance, and self-reported disability.Design: Cross-sectional cohort.Setting: Department of Veterans' Affairs Medical Center.Patients: One hundred community-dwelling elderly unable to climb stairs step over step.Main Outcome Measures: Postural sway (area of ellipse and path length, eyes open and closed), sensorimotor (strength, sensation, range of motion, central processing time), functional performance (functional reach, timed gait, mobility skills, endurance), and disability (MOS-SF36, Falls Efficacy Scale [FES]).Results: Postural sway area measures correlated with sensorimotor measures: (1) During eyes-closed conditions, increased sway occurs in individuals with sensory deficits (p < .05); (2) Sway was positively correlated with tibialis anterior latency (p < .05); (3) Sway area measures increased with increased strength (p < .05). The sway/strength relationship may be explained by weak subjects improving their stability by limiting rather than increasing sway. Sway was not significantly correlated with any measures of physical performance. Sway was correlated with some measures of disability: (1) Eyes-closed measures of postural sway were correlated with FES scores (p < .05); (2) Sway was not correlated with the MOS-36 physical functioning question. When controlling for functional measures, eyes-closed measures of sway significantly predicted FES scores (p < .03).Conclusions: Measures of postural sway are more likely capturing sensorimotor deficits rather than differentiating functional performance abilities, and the relationship between postural sway and self-reported disability is inconsistent.
