摘要：

背景：近年来兴起的三维运动解析技术，可获得多项行走过程中的生物力学参数，代表了目前步态生物力学研究的先进水平。目前该技术在国外开展较多，而国内则较少。国内有限的研究主要集中在对偏瘫患侧下肢矢状面上运动的分析。
目的：对偏瘫患者步行运动进行三维立体运动学分析，与正常步态对比，分析脑卒中偏瘫步态的运动学变化特征。
方法：运用三维运动解析系统，对10例首发缺血性脑卒中偏瘫患者进行步态分析，以10例健康者作为对照。检测健康对照组步行过程中的基本时空参数、步态周期参数与骨盆三维运动角度参数，并对其运动过程中的对称性进行分析。检测两组下肢髋、膝、踝关节的三维运动学角度参数，对比两组下肢关节运动在矢状面、横断面与冠状面上的变化特征。
结果与结论：偏瘫步态表现出下肢运动膝关节屈曲受限，膝关节活动度减小。髋关节内收、旋内不足，外展与旋外角度增大。提示三维运动解析系统测试可测定偏瘫患者步行功能，定量评价偏瘫患者下肢关节运动变化，从而进行相应针对性的稳定性与协调性训练。

Abstract:

BACKGROUND: Three-dimensional kinematic analysis can be used to obtain various biomechanical parameters in walking, which represents advanced level of gait biomechanics. This technique is not mature in domestic application. Current domestic studies mainly focus on analysis of sagittal plane of hemiplegia lower limb. 
OBJECTIVE: To explore the characters of the stroke hemiplegia gait using three-dimensional kinematic analysis.
METHODS: The 10 hemiplegia gait patients and 10 normal gait volunteers as control were subjected to gait analysis using three-dimensional kinematic analysis system. The basic time-space parameter, gait cycle parameter and pelvis three-dimensional motion angle of normal controls, and the symmetry during motion were analyzed. The three-dimensional motion angle parameters of hip, knee and ankle of two groups were analyzed. The hemiplegia gait character of the lower limb in sagital plane, transverse plane and frontal plane of two groups was compared.
RESULTS AND CONCLUSION: The hemiplegia gait manifested as follows: The knee flexion and range of motion were restricted; the hip adduction restricted, abduction and external rotation became larger. The motion analysis system can evaluate hemiplegic gait, quantitatively evaluate the lower limb motion changes, thereby providing the availability information in rehabilitation
