Background

There is limited data on fast gait speed and spatial-temporal parameters across age groups among Asian adults, and the associations between upper and lower extremity muscle strength with gait.

Research question

What values characterise fast gait spatiotemporal parameters across the age groups of an Asian population? Are hand grip strength (HGS) and knee extension strength (KES) associated with fast gait speed and spatiotemporal parameters?

Methods

Healthy community-living adults between 21–90 years (n = 487) were recruited. Fast gait was assessed using a 6 m instrumented walkway, and spatiotemporal parameters including variability for fast gait speed, stride length, stride width, stride time, stance time, swing time, single support time and double support time were analysed. Maximum HGS and KES were also assessed. Linear regression modelling was used to explore the association of HGS and KES with fast gait speed, spatiotemporal parameters and their variability.

Results

Age reduced fast gait speed and stride length, but increased stride width, stance time, stride time and double support time. Age increased all investigated gait variabilities except stride width variability. Gender differences were observed for all gait features except for fast gait speed and double support time. Both HGS and KES were positively associated with fast gait speed in both young and old adults. KES was positively associated with spatiotemporal variations in stride length, stride time, stance time and double support time. HGS was also significantly associated with two additional temporal parameters – positively with swing time and negatively with double support time variability.

Significance

The data from this study contributes to reference values database for the use of fast gait assessments in adults.

成人快速步态时空参数及其与肌肉力量的关系– Yishun研究

背景

关于亚洲成年人中各个年龄段的快步态速度和时空参数以及上下肢肌肉力量与步态之间的关联的数据有限。

研究问题

在亚洲人口的各个年龄段中,哪些值代表快速步态时空参数?握力(HGS)和膝盖伸展强度(KES)是否与快速步态速度和时空参数相关?

方法

招募了21-90岁(n = 487)之间健康的社区居民。使用6 m仪器走道评估快速步态,并分析时空参数,包括快速步态的变异性,步幅长度,步幅宽度,步幅时间,站立时间,挥杆时间,单支撑时间和双支撑时间。还评估了最大HGS和KES。线性回归模型用于探讨HGS和KES与快速步态速度,时空参数及其变异性的关系。

结果

年龄降低了快速步态速度和步幅,但增加了步幅,站姿时间,步幅时间和双支撑时间。年龄增加了所有研究的步态变异性,步幅宽度变异性除外。除步态速度快和支撑时间延长外,所有步态特征均观察到性别差异。无论是年轻人还是老年人,HGS和KES均与步态速度快呈正相关。KES与步幅,步幅,站立时间和双支撑时间的时空变化呈正相关。HGS还与另外两个时间参数显着相关–与挥杆时间成正比,与双支撑时间可变性成反比。

意义

这项研究的数据有助于参考值数据库,用于成年人的快速步态评估。
