Abstract

Objectives: The association between the amount of physical activity and the brain structure in patients with stroke is unclear. Therefore, this study aimed to evaluate the structural characteristics of the brain in patients with chronic stroke engaging in varying levels of physical activity.

Methods: This study included 10 healthy participants and 10 patients with stroke. Structural images were obtained, and the physical activity of patients with stroke was measured using a triaxial accelerometer. Additionally, the brain structure was assessed using voxel-based morphometry for gray and white matter volumes. The analysis software used were Statistical Parametric Mapping 12 and MATLAB version R2020a. The differences in brain structure between healthy participants and stroke patients were investigated. The brain regions associated with the amount of physical activity were analyzed.

Results: There was a significant decrease in the gray matter volume of the contralesional cerebellum and ipsilesional thalamus in stroke patients when compared with healthy participants (p < 0.001, uncorrected). Patients with stroke showed a positive correlation between physical activity and the volume of the ipsilesional precentral gyrus and ipsilesional entorhinal area (p < 0.001, uncorrected).

Conclusions: The amount of physical activity in patients with chronic hemiplegic stroke is associated with brain gray matter mass.

慢性中风患者的运动量与大脑结构之间的关系。

目的：脑卒中患者的运动量与大脑结构之间的关系尚不清楚。因此，本研究旨在评估不同运动量的慢性中风患者的大脑结构特征：本研究包括 10 名健康参与者和 10 名中风患者。方法：本研究包括 10 名健康参与者和 10 名脑卒中患者，获得了脑结构图像，并使用三轴加速度计测量了脑卒中患者的体力活动。此外，还使用基于体素的形态测量法评估了大脑结构的灰质和白质体积。使用的分析软件是统计参数映射 12 和 MATLAB R2020a 版本。研究调查了健康参与者与脑卒中患者大脑结构的差异。分析了与运动量相关的脑区：结果：与健康参试者相比，脑卒中患者对侧小脑和同侧丘脑灰质体积明显减少（p p 结论：脑卒中患者的体力活动量与健康参试者相比明显减少（p p）：慢性偏瘫脑卒中患者的运动量与脑灰质体积有关。
