摘要： 目的研究脑卒中偏瘫患者的步态特点。方法49 例脑卒中偏瘫患者分成两组，其中观察组33 例，不佩戴矫形器，裸足进行三维视频步态分析，与健康成年人步态参数进行比较；对照组16 例，佩戴固定式踝足矫形器(AFO)进行步态分析，与观察组比较。结果与正常人相比，观察组步长、跨步长、步频明显减小，步宽增大，步速减慢；步态周期延长，其中双腿支撑期时间和所占步态周期比例明显延长，单腿支撑期所占步态周期比例明显缩短(P<0.01)；偏瘫患者是否应用AFO，步态运动学参数无显著性差异(P>0.05)。结论脑卒中偏瘫患者步速慢、步态周期延长、双腿支撑期比例延长、单腿支撑期比例缩短是其主要运动学特点。

Abstract: Objective To explore the characteristics of hemiparetic gait for stroke patients. Methods 49 stroke patients were allocated to two groups: experimental group (n=33) received 3D-video gait analysis, and control group (n=16) received the gait analysis with ankle-foot orthosis (AFO). The kinematic parameters were compared between two groups, and the experimental group with normal gaits. Results Compared with the normal gaits, the step, stride, step frequency, gait velocity, and the percentage single support in gait cycle decreased significantly,and gait width, and the percentage in gait cycle of double support increased significantly in the experimental group (P<0.01). There was no significant difference in kinematic parameters beween the experimental group and the control group (P>0.05). Conclusion The major kinematic characteristics of hemiparetic gait are slow velocity, long cycle, relative decrease of single support of weak limb, and increase of double support.
