- Abstract: Objective To use functional magnetic imaging (fMRI) technology for exploring the differences in degree centrality (DC) and coefficient of variation of dynamic degree centrality (DDC) in stroke patients before and after acupuncture. Methods A total of 18 stroke patients with left hemiplegia within a month after onset were enrolled in the study. After general information acquisition and Brunnstrom and Fugl-Meyer assessments, the fMRI images of resting-state and acupuncture-state were collected, and the DC and coefficient of variation of DDC of the whole brain were compared. Partial correlation analysis method was used to analyze the corrections of DC and coefficient of variation of DDC with clinical data and assessment scores. Results Statistical differences were found in DC at the left inferior parietal lobule between acupuncture-state and resting-state (P<0.05) , and in the coefficient of variation of DDC at the right superior frontal gyrus and the right middle frontal gyrus between acupuncture-state and restin-state (P<0.05). After correction, there were correlations between age and the acupuncture-state coefficient of variation of DDC at the left inferior parietal lobule, between the course of disease and the resting-state coefficient of variation of DDC at the left inferior parietal leaflet lobule, between Brunnstrom score of lower limbs and the acupuncture-state DC at the right superior frontal gyrus and the right middle frontal gyrus. Conclusion The DC and the coefficient of variation of DDC of acupuncture-state are different from those of resting-state, and the coefficient of variation of DDC is related to the course of disease, age and motor function, indicating the regulatory effects of acupuncture on brains functions of stroke patients, especially the exercise-related functions, and reflecting the continuous changes of brain functions during needle retention, which provides evidence support for needle retention.
