Effect on Cerebral Functional Regions of Needling at Waiguan(SJ5) of the Heakthy Limb in Ischemic Stroke Patients

Objective:To observe the activation/deactivation of the cerebral functioanl regions during needling at Waiguan(SJ5)of the healthy limb in ischemic stroke patients by the functional magnetic resonance imaging(fMRI).Methods:Six ischemic stroke patients were stimulated by eedling at SJ5 of the healthy limb under the the block experimental design,and received the cerebral fMRI scan in the mean time.The statistical parametric mapping(SPM2) software was used to preprocess the data of the fMRI.Results:Needing the right SJ5 of left hemiplagia patients resulted in balateral cerebral regions activations It showed that the activations were relatively centralized in BA 18,19,20,21,22,37,39 and 46,and posterior lobe,amygdala cerebelli and declivis of the cerebellum,.The deactivations were relatively centralized in BA 3,4,9,10,11,18,19,21,36,38,46 and 47 and posterior lobe of cerebellum.Conclusion:The cerebral regions in processing language,somatic sensory sensations and motor execution were actived/deactived during needing at SJ5 of the healthy side in the hemiplegic patients,which might be the possible mechanism of treating cerebral infarct by needling at SJ5 of the healthy side.
