Abstract

Background: Stroke often results in physical impairments. Physical activity is crucial for rehabilitation, enhancing mobility, strength, and overall health. This study examines the association between Timed Up-and-Go (TUG) test performance and changes in physical activity to improve lower extremity physical function.

Methods: The MOBITEC-Stroke Cohort Study ("Recovery of mobility function and life-space mobility after ischemic stroke") included patients with a first incidence of stroke. Data assessed 3 and 12 months after stroke were used for analysis. Linear regression model adjusted for age, sex, instrumental activities of daily living, Falls Efficacy Scale-International, modified Ranking Scale, and National Institutes of Health Stroke Scale-score was used to examine the relationship between lower extremity physical function (i.e., TUG) and change in physical activity (i.e., minutes of physical activity measured with a wrist-worn accelerometer over 1 week).

Results: Longitudinal data of 49 patients (65% male, mean age 71.2 (SD: 10.4) years) were analyzed. Mean daily physical activity was 291.6 (SD: 96.2) min at 3 months and 298.9 (SD: 94.4) min at 12 months, with a change from 3 to 12 months of 7.3 min (95% CI: -9.4 to 24.0; p = 0.394) post-stroke. We observed significant relationships between the baseline TUG performance and the change in total physical activity over 9 months (p = 0.011) and between the change of TUG performance over time and the change in total physical activity (p = 0.022).

Conclusion: Our findings indicate that better initial lower extremity physical function and higher improvements in function over time are associated with a greater increase in physical activity levels after stroke. This suggests that interventions aimed at maintaining and improving lower extremity physical function may positively affect physical activity levels.

缺血性中风后下肢身体功能与体育锻炼之间的关系:MOBITEC-Stroke 项目的纵向研究结果。
背景:中风通常会导致肢体障碍。体育锻炼对于康复、增强活动能力、力量和整体健康至关重要。本研究探讨了定时起立行走(TUG)测试成绩与体育活动变化之间的关联,以改善下肢的身体功能:方法:MOBITEC-中风队列研究("缺血性中风后行动功能和生活空间活动能力的恢复")纳入了首次发病的中风患者。中风后 3 个月和 12 个月的评估数据用于分析。线性回归模型调整了年龄、性别、日常生活工具活动、国际跌倒功效量表、改良等级量表和美国国立卫生研究院卒中量表评分,用于研究下肢身体功能(即 TUG)与身体活动变化(即使用腕戴式加速度计测量一周内身体活动的分钟数)之间的关系:分析了 49 名患者(65% 为男性,平均年龄 71.2 岁(标准差:10.4 岁))的纵向数据。卒中后 3 个月和 12 个月的平均每日体力活动时间分别为 291.6 (SD: 96.2) 分钟和 298.9 (SD: 94.4) 分钟,从 3 个月到 12 个月的变化为 7.3 分钟 (95% CI: -9.4 到 24.0; p = 0.394)。我们观察到基线TUG成绩与9个月内总体力活动量的变化(p = 0.011)以及TUG成绩随时间的变化与总体力活动量的变化(p = 0.022)之间存在明显关系:我们的研究结果表明,卒中后较好的初始下肢肢体功能和随时间推移较高的功能改善与较高的体力活动水平相关。这表明,旨在维持和改善下肢身体功能的干预措施可能会对身体活动水平产生积极影响。
