虽然因素分析的特点是速度，节奏和变异性的因素，解释在老年人的步态表现的差异，综合分析，包括许多步态参数尚未进行，许多这些参数的规范性数据缺乏。本研究的目的是对近二十多个时空步态参数进行因子分析，并为70岁以上健康，身体健全的男性和女性的步态参数的规范数据库做出贡献。数据是从参加马约诊所衰老研究的294名参与者中提取的。时空步态数据是在参与者完成两次5.6米电子走道（GAITRite®）行走时获得的。时空步态表现的五个主要领域被确定：一个“节奏”域的特点是节奏和时间参数，如步幅时间，一个“相”域的特点是时间相参数，构成不同的部门的步态周期，一个“可变性”域包括步态周期和步骤的可变性参数;“步速”域的特征在于包括步态速度、步长和步幅的参数;而“支撑基础”域的特征在于步宽和步宽可变性。有几个领域在男女之间存在差异，在不同年龄组之间也存在差异。23步态参数的参考值，研究人员或临床医生可以用来评估和解释老年人的步态功能障碍。
While factor analyses have characterized pace, rhythm and variability as factors that explain variance in gait performance in older adults, comprehensive analyses incorporating many gait parameters have not been undertaken and normative data for many of those parameters are lacking. The purposes of this study were to conduct a factor analysis on nearly two dozen spatiotemporal gait parameters and to contribute to the normative database of gait parameters from healthy, able-bodied men and women over the age of 70. Data were extracted from 294 participants enrolled in the Mayo Clinic Study of Aging. Spatiotemporal gait data were obtained as participants completed two walks across a 5.6-m electronic walkway (GAITRite®). Five primary domains of spatiotemporal gait performance were identified: a “rhythm” domain was characterized by cadence and temporal parameters such as stride time; a “phase” domain was characterized by temporophasic parameters that constitute distinct divisions of the gait cycle; a “variability” domain encompassed gait cycle and step variability parameters; a “pace” domain was characterized by parameters that included gait speed, step length and stride length; and a “base of support” domain was characterized by step width and step width variability. Several domains differed between men and women and differed across age groups. Reference values of 23 gait parameters are presented which researchers or clinicians can use for assessing and interpreting gait dysfunction in aging persons.
