The most common pattern of walking impairment poststroke is hemiparetic gait, which is characterized by asymmetry associated with an extensor synergy pattern of hip extension and adduction, knee extension, and ankle plantar flexion and inversion. There are characteristic changes in the spatiotemporal, kinematic and kinetic parameters, and dynamic electromyography patterns in hemiparesis, which may be assessed most accurately in a motion studies laboratory. An understanding of normal human gait is necessary to assess the complex interplay of motor, sensory, and proprioceptive loss; spasticity; and/or ataxia on hemiparetic gait.
中风后最常见的步行障碍模式是偏瘫步态，其特征是不对称，伴有髋部伸展和内收、膝部伸展以及踝部跖屈和内翻的伸肌协同模式。偏瘫患者在时空、运动学和动力学参数以及动态肌电图模式方面存在特征性变化，这些变化在运动研究实验室中评估最为准确。了解正常人类步态对于评估运动、感觉和本体感觉丧失、痉挛和/或共济失调对偏瘫步态的复杂相互作用是必要的。
