- W3032325763 abstract "ObjectiveTo observe the integrity of white matter fibers and functional regions of the brain in response to acupuncture and to explore acupuncture's mechanism when the pyramidal tract is damaged.MethodsTwenty cerebral infarction survivors with left upper limb hemiplegia as their main sequela were examined using diffusion-tensor imaging (DTI) and blood oxygenation level dependent functional magnetic resonance imaging(BOLD-fMRI) while receiving acupuncture at the left HeGu and left WaiGuan acupoints. The experiments were conducted 3-6 weeks after onset of the hemiplegia. The DTI raw data were reconstructed to display 3-dimensional pyramidal tract images and the damage to the right lateral tract was observed. The BOLD-fMRI data were processed using SPM8 software to show the excited brain regions.ResultsThe right lateral pyramidal tracts of the 20 patients were interrupted with different degrees of damage. The regions excited during the acupuncture were the bilateral nuclei of the basal ganglia and the thalamus. The left medial frontal gyrus, the left superior frontal gyrus and the left insula also had obviously excited regions. There were also a large number of excited regions in the reticular formation, the red nucleus and the substantia nigra of the midbrain, in the left cerebellum's hillside and dentate nucleus, and in the right prefrontal cortex. Minor excitement was also observed in the left inferior temporal gyrus, the fusiform gyrus, the left middle frontal gyrus, the left inferior frontal gyrus, the anterior precuneus bilaterally, the right cerebellum hillside and the right parietal cortex. The left posterior cingulate gyrus, the right occipital lobe and the right superior frontal gyrus all showed below-normal excitation.ConclusionThe pyramidal tract is damaged in hemiplegic stroke patients, but extrapyramidal systems also play a significant role in determining the effects of acupuncture. DTI used together with BOLD-fMRI allows studying the mechanism through which acupuncture helps rehabilitate cerebral infarction patients.Key words: Cerebral infarction; Pyramidal tract; Acupuncture; Functional magnetic resonance imaging; Diffusion tensor imaging; Hemiplegia" @default.
