Abstract:

Stroke is the main cause of permanent disability. Early diagnosis, treatment and prevention of recurrence are very important. Acupuncture therapy can safely and effectively improve motor dysfunction after stroke. In this paper, fMRI studies on motor dysfunction in ischemic stroke and fMRI clinical studies on acupuncture in the treatment of motor dysfunction in ischemic stroke in the past 10 years were searched, and the brain functional connection mechanism of acupuncture in the treatment of motor dysfunction in ischemic stroke was discussed by analyzing the literature. A total of 11 ROI-based fMRI were included to observe the clinical studies of acupuncture in the treatment of patients with motor dysfunction after stroke. It was found that the central mechanism of acupuncture in the treatment of motor dysfunction after stroke was mainly to activate the functional connections of primary motor cortex, posterior cingulate gyrus, precuneus and other brain regions. It suggests that the enhancement of functional connectivity in primary motor cortex may be the central mechanism of acupuncture in improving motor dysfunction after stroke.
