Abstract:
Objective To compare the immediate effects of acupuncture at the true and false acupoints of Yanglingquan on functional connectivity in sensorimotor network(SMN)and dorsal attentional network(DAN)of stroke patients based on functional magnetic resonance imaging(fMRI)technology;To explore the central regulatory mechanism and acupoint specificity of acupuncture in stroke patients with hemiplegia.Methods Totally 20 patients with stroke and hemiplegia were included in the study.fMRI scans of acupuncture at the true and false acupoints of Yanglingquan were performed once every 2 weeks,and motion-related SMN and DAN were extracted by independent component analysis to compare the differences in functional connectivity.Results In SMN,after acupuncture at the Yanglingquan true acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior central gyrus,superior temporal gyrus,inferior frontal gyrus,cuneiform lobe,and anterior cuneiform lobe,as well as the left middle temporal gyrus,occipital gyrus,superior temporal gyrus,parahippocampal gyrus,inferior frontal gyrus,and superior temporal gyrus.After acupuncture at the Yanglingquan false acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior central gyrus,superior frontal gyrus,middle frontal gyrus,and cingulate gyrus,as well as the left medial frontal gyrus,anterior cingulate gyrus,lentiform nucleus,and caudate nucleus.In DAN,after acupuncture at the Yanglingquan true acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior cingulate lobe,superior temporal gyrus,middle temporal gyrus,and occipital gyrus,as well as the left cingulate gyrus,posterior cingulate gyrus,and anterior cingulate lobe.After acupuncture at the Yanglingquan false acupoint,the functional connectivity was enhanced compared with before acupuncture,and the enhanced brain areas included the right anterior cingulate gyrus,left anterior cingulate gyrus,and medial frontal gyrus.Conclusion Acupuncture at Yanglingquan can activate SMN and DAN bilateral related brain regions in patients with hemiplegia,which may promote the recovery of motor function by regulating the initiation and execution of motor activities,and has more acupoint specificity compared with false acupoint.
