Mobility, specifically community walking, is important, but often limited among survivors of stroke. The factors that influence the recovery of community walking are not clearly understood.
The purpose of this research was to examine mobility disability following stroke, specifically: (1) the association between subjective and objective measures of participation in community walking and (2) the association between personal factors and participation in community walking.
A cross-sectional study design was used.
Fifty community-dwelling survivors of stroke, aged 50 to 79 years, were enrolled in the study. Participation in community walking was measured subjectively (perceived difficulty and satisfaction) and objectively using self-report data (number of trips and walking-related activities) and step data (pedometer). The association between subjective and objective measures of participation was analyzed using Pearson correlation. The association of personal factors (age, sex, number of comorbidities, fatigue, depression, balance and fall self-efficacy, and importance of walking) with measures of participation was analyzed using multiple linear regression.
Subjective and objective measures of participation were weakly associated. Self-efficacy was the only personal factor that was strongly associated with both subjective and objective measures of participation. Personal factors explained 27% to 55% of the variability in participation in community walking.
Limitations included a small sample size and limited diversity among participants. Reliability of the pedometer used in this study has not been established in the stroke population.
Subjective and objective measures of participation in community walking were only weakly correlated, suggesting that they measure different aspects of mobility; thus, to fully capture participation, it is critical to measure both. Personal factors were associated with subjective and objective measures of participation and are important in explaining variability in community walking following stroke.
移动性，特别是社区行走，对中风幸存者很重要，但通常受到限制。影响社区行走康复的因素尚不清楚。
本研究旨在检查中风后的移动障碍，具体为：（1）参与社区行走的主观和客观测量之间的关联，以及（2）个人因素与参与社区行走之间的关联。
采用横断面研究设计。
研究纳入了 50 名年龄在 50 至 79 岁之间、居住在社区的中风幸存者。社区行走的参与情况通过主观（感知困难和满意度）和客观（自我报告数据（出行次数和与行走相关的活动）和步数数据（计步器））来衡量。使用 Pearson 相关分析来分析参与的主观和客观测量之间的关联。使用多元线性回归分析个人因素（年龄、性别、合并症数量、疲劳、抑郁、平衡和跌倒自我效能以及行走的重要性）与参与措施的关联。
参与的主观和客观测量之间存在弱关联。自我效能是唯一与主观和客观参与测量均具有强关联的个人因素。个人因素解释了社区行走参与度 27%至 55%的变异性。
研究的局限性包括样本量小且参与者多样性有限。本研究中使用的计步器的可靠性尚未在中风人群中建立。
参与社区行走的主观和客观测量之间仅存在弱相关性，这表明它们测量了移动性的不同方面；因此，为了全面捕捉参与情况，测量两者都很重要。个人因素与主观和客观的参与测量相关，并且是解释中风后社区行走变异性的重要因素。
