Abstract：
BACKGROUND: High collision rates and frequency of entering the opening from non-paretic sides are associated with collision in individuals with stroke.
OBJECTIVE: To identify factors associated with collision avoidance behavior when individuals with stroke walked through narrow openings.
METHODS: Participants with subacute or chronic stroke walked through a narrow opening and had to avoid colliding with obstacles. Multiple regression analyses were conducted with pathophysiology, motor function, and judgment ability as predictor variables; collision rate and frequency of entering the opening from non-paretic sides were outcome variables.
RESULTS: Sixty-one eligible individuals with stroke aged 63±12 years were enrolled. Thirty participants collided twice or more and 37 entered the opening from the non-paretic side. Higher collision occurrence was associated with slower Timed Up and Go tests and left-right sway (odds ratios, 1.2 and 5.6; 95% confidence intervals, 1.1-1.3 and 1.3-28.2; p = .008 and.025, respectively). Entering from non-paretic sides was associated with lesions in the thalamus, left-sided hemiplegia, and Brunnstrom stage 3 or lower (odds ratios, 6.6, 8.7, and 6.7; 95% confidence intervals, 1.3-52.5, 2.5-36.5, and 1.2-57.5; and p = .038,.001, and.048, respectively).
CONCLUSIONS: Walking ability is associated with avoiding obstacle collision, while pathophysiological characteristics and degree of paralysis are associated with a preference for which side of the body enters an opening first. Interventions to improve walking ability may improve collision avoidance. Avoidance behavior during intervention varies depending on the lesion position.

摘要：
背景：从非侧面进入开口的高碰撞率和频率与中风个体的碰撞有关。
目的：确定中风个体走过狭窄开口时与避免碰撞行为相关的因素。
方法：亚急性或慢性中风的参与者穿过狭窄的开口，必须避免与障碍物碰撞。病理生理学进行多元回归分析，运动功能,和判断能力作为预测变量；碰撞率和从非侧面进入开口的频率是结果变量。
结果：纳入61名符合资格的卒中患者，年龄为63±12岁。30名参与者碰撞两次或更多次，37名参与者从非麻痹侧进入开口。较高的碰撞发生率与较慢的TimedUp和Go测试以及左右摇摆有关(赔率比，1.2和5.6；95%置信区间，1.1-1.3和1.3-28.2；p分别为.008和.025）。从非麻痹侧进入与丘脑病变有关，左侧偏瘫,和Brunnstrom第三阶段或更低(赔率比，6.6、8.7和6.7；95%置信区间，1.3-52.5、2.5-36.5和1.2-57.5；分别为p=.038、.001和.048）。
结论：步行能力与避免障碍物碰撞有关，而病理生理特征和瘫痪程度与身体哪一侧先进入开口的偏好有关。改善行走能力的干预措施可以改善防撞。介入期间的回避行为根据病变位置而变化。
