Objective: To investigate the association of multiple predictors (gait ability, depression, balance, strength of knee extensors on the paretic side, and mobility) with community ambulation (walking speed ≥0.8 m/s) of individuals after chronic stroke.

Methods: A cross-sectional study was carried out with 60 individuals after chronic stroke with a mean age of 59 (±15.75) years. The walking speed (10-m walk test) was used to assess the outcome variable (walking speed ≥0.8 m/s) and the predictors were gait ability (ABILOCO), depression (GDS-15 Geriatric Depression Scale), balance (Berg Balance Scale), strength of knee extensors on the paretic side (modified sphygmomanometer test) and mobility (Timed Up and Go test).

Results: All predictors, except depression were independently associated with community ambulation. The mobility was associated with the walking speed, and the model also showed association when it was adjusted with the use of an assistive device.

Conclusion: Mobility (p = 0.015; OR = 0.803) and the use of an assistive device (p = 0.006) were associated with the community ambulation in individuals after stroke. This not only suggests that physical aspects, but also environment should be considered when addressing community ambulation after stroke.

目标： 研究多重预测因子（步态能力、抑郁、平衡、患侧膝关节伸肌力量和活动力）与慢性卒中后个体社区步行速度（≥0.8米/秒）之间的关联。

方法： 一项横断面研究包括60名平均年龄为59岁（±15.75）的慢性卒中患者。使用行走速度（10米步行测试）来评估结果变量（行走速度≥0.8米/秒），预测因子包括步态能力（ABILOCO）、抑郁（GDS-15老年抑郁量表）、平衡（Berg平衡量表）、患侧膝关节伸肌力量（改良血压计测试）和活动力（定时起立行走测试）。

结果： 除抑郁症外，所有预测因子均与社区步行独立相关。活动力与行走速度有关，并且当调整了辅助设备的使用后，模型也显示出关联性。

结论： 在卒中后的个体中，活动力（p = 0.015; OR = 0.803）和辅助设备的使用（p = 0.006）与社区步行相关。这不仅表明在解决卒中后社区步行问题时应考虑身体方面的问题，还应考虑环境因素。
