Abstract

Objective: Motor rehabilitation is a central contributor to motor recovery after stroke. Rehabilitation could be hampered by stroke-associated cognitive impairments such as the decreased ability to follow instructions. Rapid instructed task learning (RITL) was never directly studied in older adults and subjects with stroke. The aim of this study was to assess RITL following stroke and its underlying cognitive determinants.

Method: Thirty-one subjects with chronic stroke and 36 age-matched controls completed a computerized cognitive examination that included an antisaccade task for measuring prepotent inhibition and processing speed and stimulus-response association task (NEXT) for measuring RITL and proactive inhibition.

Results: RITL abilities were impaired after stroke (d = 0.72), together with prepotent inhibition (d = 0.71) and processing speed (d = 1.12). A correlation analysis revealed that RITL is associated with prepotent inhibition abilities and with processing speed.

Conclusions: Subjects with stroke show impairments in the ability to follow instructions, that may be related to their impaired prepotent inhibition and processing speed. The causal effect of RITL impairments on the responsivity to rehabilitation and on motor recovery should be examined. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

脑卒中后快速指令任务学习受损，与前能抑制和处理速度受损有关。

目的：运动康复是中风后运动恢复的关键因素。中风相关的认知障碍（如遵从指令的能力下降）可能会阻碍康复。快速指令任务学习（RITL）从未在老年人和中风患者中进行过直接研究。本研究旨在评估中风后的 RITL 及其潜在的认知决定因素：31名慢性中风受试者和36名年龄匹配的对照组受试者完成了计算机化认知检查，其中包括用于测量前摄抑制和处理速度的反累积任务，以及用于测量RITL和前摄抑制的刺激-反应联想任务（NEXT）：结果：脑卒中后 RITL 能力受损（d = 0.72），同时受损的还有前摄抑制（d = 0.71）和处理速度（d = 1.12）。相关分析表明，RITL 与前能动抑制能力和处理速度相关：结论：脑卒中患者遵从指令的能力出现障碍，这可能与他们的前能动抑制能力和处理速度受损有关。应研究 RITL 损伤对康复反应和运动恢复的因果影响。(PsycInfo Database Record (c) 2024 APA, 版权所有）。
