项目摘要
Gait variability has been traditionally defined as fluctuations in gait characteristics
such as step length, stance time or step width and is most often measured by standard deviation (SD) or coefficient of variation (CV). Gait variability has been shown to be a better indicator of future falls than mean spatial and temporal gait characteristics in persons who walk at near normal speed(8). Increased variability in several gait indicators, including stride time, step length, and stance time, is associated with falling, while the association of step width variability with falls has a more inconsistent relationship's(5) An increase in absolute step width is thought to lead to greater stability. Some investigators have foimd step width to be reduced in fallers(4) while others have found a nonlinear association, with both too little and too much step width variability related to falls(8)
步态变异性传统上被定义为步态特征的波动
例如步长、站立时间或步宽,并且最常通过标准偏差(SD)或变异系数(CV)来测量。在以接近正常速度行走的人中,步态变异性已被证明是未来福尔斯的更好指标,而不是平均空间和时间步态特征(8)。几个步态指标(包括步幅时间、步长和站立时间)的可变性增加与跌倒相关,而步长可变性与福尔斯的关联具有更不一致的关系(5)绝对步长的增加被认为会导致更大的稳定性。一些研究者发现,跌倒者的步宽会减少(4),而另一些研究者发现,与福尔斯相关的步宽变化太小或太大存在非线性关系(8)。
