Abstract

Aims. While studies on healthy subjects have shown a partial overlap between the motor execution and motor imagery neural circuits, few have investigated brain activity during motor imagery in stroke patients with hemiparesis. This work is aimed at examining similarities between motor imagery and execution in a group of stroke patients. Materials and Methods. Eleven patients were asked to perform a visuomotor tracking task by either physically or mentally tracking a sine wave force target using their thumb and index finger during fMRI scanning. MIQ-RS questionnaire has been administered. Results and Conclusion. Whole-brain analyses confirmed shared neural substrates between motor imagery and motor execution in bilateral premotor cortex, SMA, and in the contralesional inferior parietal lobule. Additional region of interest-based analyses revealed a negative correlation between kinaesthetic imagery ability and percentage BOLD change in areas 4p and 3a; higher imagery ability was associated with negative and lower percentage BOLD change in primary sensorimotor areas during motor imagery.

摘要

目的。虽然对健康受试者的研究表明运动执行和运动想象神经回路之间存在部分重叠，但很少有研究调查偏瘫中风患者在运动想象期间的大脑活动。这项工作旨在研究一组中风患者运动想象和运动执行之间的相似性。材料与方法。11名患者在功能磁共振成像扫描期间被要求通过用拇指和食指实际或在脑海中追踪正弦波力目标来执行视觉运动跟踪任务。已发放MIQ-RS问卷。结果与结论。全脑分析证实双侧运动前皮质、辅助运动区和对侧下顶叶小叶中运动想象和运动执行之间存在共同的神经基质。基于感兴趣区域的额外分析显示，运动觉想象能力与4p区和3a区的血氧水平依赖（BOLD）变化百分比之间呈负相关；在运动想象期间，较高的想象能力与初级感觉运动区中BOLD变化百分比为负且较低相关。
