简介：不同的专家之间仍然没有达成共识的运动学变化的主题在偏瘫步态，包括主要的变化，发生在步态周期和步态速度是否改变了模式的关节活动度。最常讨论的关节之一是knee.ACTIFIVES：本研究旨在评估膝关节的角运动学中发现的变量，并描述发现的变化，在偏瘫步态造成脑血管injuries.METHODS：本研究包括66名成年患者的两种性别的诊断，无论是右或左偏瘫造成缺血性脑血管损伤。所有受试者均进行三维步态评估，并选择膝关节的角运动学进行分析。结果：根据步态速度中位数和偏瘫侧将结果分为四组。结论：相关临床特征包括站立位负荷反应、单站位膝关节过伸、以及在摆动阶段中膝关节的峰值屈曲和运动幅度的减小。在选择最佳治疗时应考虑这些机制。我们认为，这里提出的调查结果可能有助于防止所发现的问题的发生，并确定这些问题的根源。
INTRODUCTION: There is still no consensus among different specialists on the Subject of kinematic variation during the hemiparetic gait, including the main changes that take place during the gait cycle and whether the gait velocity changes the patterns of joint mobility. One of the most frequently discussed joints is the knee.OBJECTIVES: This Study aims to evaluate the variables found in the angular kinematics of knee joint, and to describe the alterations found in the hemiparetic gait resulting from cerebrovascular injury.METHODS: This study included 66 adult patients of both genders with a diagnosis of either right or left hemiparesis resulting from ischemic cerebrovascular injury. All the participants underwent three-dimensional gait evaluation, an the angular kinematics of the joint knee were selected for analysis.RESULTS: The results were distributed into four groups formed based on the median of the gait speed and the side of hemiparesis.CONCLUSIONS: The relevant clinical characteristics included the important mechanisms of loading response in the stance, knee hyperextension in single stance, and reduction of the peak flexion and movement amplitude of the knee in the swing phase. These mechanisms should be taken into account when choosing the best treatment. We believe that the findings presented here may aid in preventing the occurrence of the problems found, and also in identifying the origin of these problems.
