摘要： 目的研究不同年龄段正常成人的步态特征。方法正常成人90名,分为20～39岁组、40～59岁组、60～70岁组,每组各30名,应用基于数字视频和图像处理的步态分析系统进行步态分析,得到时空参数、运动学参数,比较3组被试的步态参数差异,对步速与其他步态参数进行Pearson相关性分析,以判定影响步速的相关因素。结果3组正常成人的部分步态参数之间存在显著性差异,步速与步频、跨步长/身高、跨步周期、站立相时间、迈步相髋关节、膝关节最大屈曲角度有明显相关性。结论应用基于数字视频和图像处理的步态分析系统建立的国内不同年龄段正常成人步态的运动学特征模型,可供临床步态分析参考使用。

Abstract: ObjectiveTo study normal gait characteristics of healthy adults in different age groups.Methods90 healthy adults were divided into three groups according to their ages. It was 20～39 year group, 40～59 year group and 60～70 year group. They received a gait analysis with the gait analysis system based on digital video and image processing which could provide temporal-spatial parameters and kinematic parameters. The gait data of the three groups were compared. Relationships between gait speed and other gait parameters were investigated.ResultsThere were statistically significant differences in some parameters among three groups. Gait speed was significantly correlated with stride time, stride length, stance time (%), cadence, maximum flexion of hip and knee in swing phase.ConclusionThe normal gait patterns of healthy adult established with the gait analysis system based on digital video and image processing can be used as the base line to compare with abnormal gait.

Key words: gait, gait speed, gait analysis system
