摘要:

背景:三维步态分析作为一种客观步态评估方法越来越广泛应用于临床检测。但尚缺乏统一的标准来衡量正常人的步态特征。
目的:检测中国正常青年人自然行走步态数据,为临床上异常步态的分析提供参考依据。
方法:应用英国Vicon三维运动捕捉系统,对100名正常青年人进行步态测试,得到时空参数、运动学参数、运动力学参数。
结果与结论:正常青年人左右侧(髋、膝、踝关节的活动角度和垂直地板反力)曲线分布规律基本一致;髋、膝、踝关节活动角度(最初着地角度、最大屈曲角度、最大伸展角度、矢状面最大活动范围)和垂直地板反力参数(第1波峰值、谷值、第2波峰值)的左右侧相比,差异无显著性意义(P > 0.05)。说明建立的中国正常人步态数据,可供临床步态分析参考使用。

Abstract:

BACKGROUND: Three-dimensional gait analysis is an objective gait evaluation method which has been more and more widely used in clinical detection. But there is still a lack of the unified standard for evaluating the normal human gait characteristics.
OBJECTIVE: To detect the gait data in normal China young people and to provide the reference for analyzing the abnormal gait.
METHODS: Totally 100 normal China young adults were enrolled to test natural gaits using the three-dimensional motion capture system of the British Vicon to get the spatial and temporal parameters, kinematics parameters, kinetics parameters.
RESULTS AND CONCLUSION: The curves of left and right sides (hip, knee, ankle joint angle and vertical ground reaction) of normal young people distributed basically consistently. There were no statistically significant differences between the left side and the right side in data of the motion angles of the hip, knee, ankle joint (first landing angle, maximum flexion angle, maximum extension angle, maximum range of motion in sagittal plane) and the vertical ground reaction parameters (the first wave peak, valley and the second wave peak) (P > 0.05). The normal human gait data established can provide the reference for clinical gait analysis.
