People after stroke have difficulties when they undertaking two tasks simultaneously.
To investigate the relationships between dual-task performance and factors such as motor function, balance, cognitive state, and fatigue, to identify factors that have an impact on dual-task performance after a stroke.
Thirty-seven people with stroke and 38 healthy participants were assessed with 10-m walking test in different performances which were single-task-based, motor dual-task-based and cognitive dual-task-based. Results were evaluated according to the Rivermead Motor Assessment, the Static balance index, the Mini-Mental State Examination, and the Fatigue Severity Scale.
Participants with stroke were slower compared to the control group with the following mean speed values for single-task (M = 0.73 m/s, t = -7.612, < .001), motor dual-task (M = 0.70 m/s, t = -8.232, < .001), cognitive dual-task (M = 0.59 m/s, t = -7.944, < .001). For people after stroke, motor dual-task performance was significantly affected by the total motor function scores (r = 0.648, < .001), static balance (r = -0.499, < .05), and fatigue rates (r = -0.349, < .05). Furthermore, cognitive dual-task performance was affected by the total motor function score (r = 0.537, < .05) static balance (r = -0.541, < .05) and fatigue rates (r = -0.350), < .05). Multivariate factor analysis indicated that impairment in the gross function influenced motor dual-task performance (B = 0.086, = .031) and cognitive dual-task performance (B = 0.083, = .010). Cognitive dual-task performance was affected by leg-trunk function (B = 0.063, = .015) and age (B = -0.006, = .009).
The present study indicated that dual-task performance was related to motor function, balance, and fatigue, whereas gross motor function was the unique determinant of dual-task performance.
中风患者在同时进行两项任务时会遇到困难。
研究双重任务表现与运动功能、平衡、认知状态和疲劳等因素之间的关系，以确定对中风后双重任务表现有影响的因素。
对37名中风患者和38名健康参与者进行了10米步行测试，测试在基于单任务、基于运动双重任务和基于认知双重任务的不同表现形式下进行。根据Rivermead运动评估、静态平衡指数、简易精神状态检查表和疲劳严重程度量表对结果进行评估。
与对照组相比，中风患者在单任务（M = 0.73米/秒，t = -7.612，p <.001）、运动双重任务（M = 0.70米/秒，t = -8.232，p <.001）、认知双重任务（M = 0.59米/秒，t = -7.944，p <.001）中的平均速度较慢。对于中风患者，运动双重任务表现受总运动功能得分（r = 0.648，p <.001）、静态平衡（r = -0.499，p <.05）和疲劳率（r = -0.349，p <.05）的显著影响。此外，认知双重任务表现受总运动功能得分（r = 0.537，p <.05）、静态平衡（r = -0.541，p <.05）和疲劳率（r = -0.350，p <.05）的影响。多因素分析表明，总体功能受损影响运动双重任务表现（B = 0.086，p =.031）和认知双重任务表现（B = 0.083，p =.010）。认知双重任务表现受腿部-躯干功能（B = 0.063，p =.015）和年龄（B = -0.006，p =.009）的影响。
本研究表明，双重任务表现与运动功能、平衡和疲劳有关，而总体运动功能是双重任务表现的唯一决定因素。
