目的：确定独立行走的中风幸存者中不对称的患病率和严重程度，并建立速度和不对称之间的联系。设计：描述性分析。设置：加拿大医院的研究步态实验室。参与者：社区居住，独立行走的慢性中风参与者（N=54）。干预措施：不适用。主要结果测量：地上步态速度，时间和空间步长参数的对称比，以及足部和腿部的运动损伤。采用压力敏感垫收集时空参数。运动障碍的临床测量与Chedoke-McMaster Stroke Assessment.Results：30（55.5%）的参与者表现出统计学显着的时间不对称性和18（33.3%）表现出统计学显着的空间不对称性。首选速度与时间不对称性呈负相关（r = -.583，df=52 P
Objectives: To determine the prevalence and severity of asymmetry among independently ambulating stroke survivors and to establish the association between velocity and asymmetry.Design: Descriptive analysis.Setting: Research gait laboratory in a Canadian hospital.Participants: Community-dwelling, independently ambulating participants (N=54) with chronic stroke.Interventions: Not applicable.Main Outcome Measures: Overground gait velocity, symmetry ratios for temporal and spatial step parameters, and motor impairment of the foot and leg. Spatiotemporal parameters were collected with a pressure-sensitive mat. Motor impairment was measured clinically with the Chedoke-McMaster Stroke Assessment.Results: Thirty (55.5%) participants showed statistically significant temporal asymmetry and 18 (33.3%) exhibited statistically significant spatial asymmetry. Preferred velocity was negatively associated with temporal asymmetry (r = -.583, df=52 P
