中国正常成人步行时空参数分析

Temporal-spatial parameters of gait:reference data of normal subjects from Chinese adults

目的:探讨中国正常成人的步行特征,为临床步态分析提供科学参考依据。方法:365名正常受试者,按性别、年龄分为20—29岁组、30—39岁组、40—49岁组、50—59岁组、60—75岁组共10组。应用人体步态垫测量与分析系统,测试受试者自由行走时的步速、步长、步幅、步长时间、摆动时间、支撑时间、单足支撑时间、双足支撑时间等时空参数,并对每位受试者的身高、体重进行测试。结果:年龄组内平均步速,除30—39岁组、60—75岁组外,男性均大于女性(P<0.05),50岁以后,男、女步速均减慢,与50岁以前相比差异具有显著性(P<0.01);各年龄组步长,男性均大于女性(P<0.05),女性步长在50岁以后减小,与50岁以前相比差异具有显著性(P<0.01),男性步长在60岁以后减小,明显小于60岁以前步长(P<0.01)。结论:应用人体步态垫测量与分析系统,首次建立中国正常成人步行时空参数值参考范围,初步揭示中国正常成人的步行时空特征。

Objective：To research temporal-spatial parameters characteristics of gait of Chinese normal adults to provide reference for gait analysis in clinic.Method：A total of 365 healthy adults were divided into 10 groups according to their ages and gender：20—29 years group,30—39 years group,40—49 years group,50—59 years group and 60—75 years group.All the subjects received gait analysis with the gait mat（a gait analysis system） which could provide temporal-spatial parameters：velocity,step length,stride length,step time,swing time,stance time and single support time and double support time etc.Height and weight of the subjects were also been measured.Result：The men walked faster than women except 30—39 and 60—75 years groups（P0.05）.The velocity decreased with age in both genders and started to decrease after 50 years old for both men and women（P0.01）.The step lengths of men were longer than that of women（P0.05）,and it started to decrease after 50 years old for women and after 60 years old for men（P0.01）.Conclusion：This is the first time to establish the reference base of temporal-spatial parameters of Chinese normal adults with gait mat and to reveal the characteristics of temporal-spatial parameters of gait of Chinese normal adults.
