目的：确定中风患者踝关节损伤对步态速度和对称性的最重要因素。设计：方便样本的横断面描述性分析。设置：台湾医疗中心和市立医院门诊康复和神经血管神经科的患者。参与者：68名中风后偏瘫患者，具有独立行走能力。干预措施：不适用。主要结果测量：采用手持式测力计测量跖屈肌和背屈肌的最大等长肌力。以肌电活动的斜率、肌电活动的痉挛指数、肌电活动的斜率、肌电活动的斜率、肌电pantarflexors的被动僵硬度表明背屈范围小于正常值。位置误差以踝关节本体感觉缺失程度为指标，通过关节位置觉的评定来衡量。结果：回归分析显示背屈肌力量是影响步态速度和时间对称性的最重要因素（步态速度的R-2 =.30，P
Objective: To identify the most important factor among the ankle impairments on gait velocity and symmetry in stroke patients.Design: Cross-sectional, descriptive analysis of convenience sample.Setting: Patients from outpatient rehabilitation and neurovascular neurology departments in medical centers and municipal hospitals in Taiwan.Participants: Sixty-eight subjects with hemiparesis poststroke with the ability to walk independently.Interventions: Not applicable.Main Outcome Measures: Maximal isometric strength of plantarflexors and dorsiflexors were examined by a handheld dynamometer. Spasticity index, slope magnitudes between electromyographic activities, and muscle lengthening velocity of gastrocnemius during lengthening period of stance phases were measured to represent the dynamic spasticity. Passive stiffness of pantarflexors was indicated by degrees of dorsiflexion range that were less than normative values. Position error was measured by the degree of proprioceptive deficits of ankle joint by evaluating the joint position sense. Gait velocity, symmetry, and other gait parameters were measured by the GAITRite system.Results: Regression analyses revealed that the dorsiflexors strength was the most important factor for gait velocity and temporal symmetry (R-2 =.30 for gait velocity, P
