背景资料：关于亚洲成年人不同年龄组的快速步态速度和时空参数，以及上肢和下肢肌肉力量与步态之间的关联的数据有限。研究问题：亚洲人群各年龄组的快速步态时空参数值是多少？手握力（HGS）和膝关节伸展力量（KES）与快速步态速度和时空参数相关吗？方法：21岁至22岁的健康社区生活成年人。90岁（n = 487）。使用6 m仪器化人行道评估快速步态，并分析时空参数，包括快速步态速度、步幅、步宽、步幅时间、站立时间、摆动时间、单支撑时间和双支撑时间的变异性。还评估了最大HGS和KES。采用线性回归模型分析HGS和KES与快速步态速度、时空参数及其变异性的关系。结果：增龄降低了快速步态速度和步长，增加了步长、站立时间、跨步时间和双支撑时间。除步幅宽度变异性外，所有研究的步态变异性均随着年龄的增加而增加。除快速步态和双支撑时间外，所有步态特征均存在性别差异。HGS和KES都与年轻人和老年人的快速步态速度呈正相关。KES与步幅、跨步时间、站立时间和双支撑时间的时空变化呈正相关。HGS也显着相关的两个额外的时间参数？正与摆动时间和负与双支撑时间variation.Significance：从这项研究的数据有助于参考值数据库中使用的快速步态评估成人。
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.
