Purpose. To determine which characteristics are most associated with free-living physical activity in community-dwelling ambulatory people after stroke. Method. Factors (age, gender, side of stroke, time since stroke, BMI, and spouse), sensory-motor impairments (weakness, contracture, spasticity, coordination, proprioception, and balance), and non-sensory-motor impairments (cognition, language, perception, mood, and confidence) were collected on 42 people with chronic stroke. Free-living physical activity was measured using an activity monitor and reported as time on feet and activity counts. Results. Univariate analysis showed that balance and mood were correlated with time on feet (r = 0.42, 0.43, P < 0.01) and also with activity counts (r = 0.52, 0.54, P < 0.01). Stepwise multiple regression showed that mood and balance accounted for 25% of the variance in time on feet and 40% of the variance in activity counts. Conclusions. Mood and balance are associated with free-living physical activity in ambulatory people after stroke residing in the community.
目的。确定中风后社区中能独立行走的人群中，哪些特征与日常身体活动最为相关。方法。收集了42例慢性中风患者的相关因素（年龄、性别、中风部位、中风后时间、体重指数和配偶情况）、感觉运动障碍（虚弱、挛缩、痉挛、协调、本体感觉和平衡）以及非感觉运动障碍（认知、语言、感知、情绪和信心）。使用活动监测器测量日常身体活动，并以站立时间和活动计数来报告。结果。单因素分析表明，平衡和情绪与站立时间相关（r = 0.42，0.43，P < 0.01），也与活动计数相关（r = 0.52，0.54，P < 0.01）。逐步多元回归表明，情绪和平衡分别解释了站立时间变异的25%和活动计数变异的40%。结论。情绪和平衡与社区中中风后能独立行走人群的日常身体活动相关。
