Abstract:
Objective To observe and compare the effects of acupuncture and acupuncture plus speech therapy on activation of the brain areas in aphasic patients by use of oxygenation level dependent-functional magnetic resonance imaging (BOLD-fMRI).Methods Twenty patients with aphasia caused by stroke were randomized into two groups by use of random number table (10 cases in each group):an experimental group subject to acupuncture treatment combined with speech therapy,and a control group subject to speech therapy only.All the cases were dextromanuality.On admission and after 1 month of treatment,BOLD-fMRI was used to test signals of the activated brain areas of both group,and Aphasia Battery of the Chinese (ABC) was employed to evaluate the changes of speech ability of the patients.Results During the study,1 case from control group was unable to do the post-intervention evaluation due to onset of the second stroke.The effective rates of the control and experimental group were 55.56％ and 100.00％,respectively,and recovery of verbal ability in experimental group was significantly better than in control group (P ＜ 0.05).The active volume and extent in brain were significantly increased in both groups (P ＜0.05),and a comparison between the two groups showed that the changes in activation volume and extent of the brain were significantly greater extensive in experimental group than in the control group,especially in bilateral frontal lobe,cuneus,posterior cingulate gyrus,lingual gyrus,occipital lobe,splenium of corpus callosum,cerebellar hemisphere,and the left precentral gyrus,post-central gyrus,paracentral lobule,temporal lobes,angular gyrus,precuneus,and the right hippocampus,parahippocampus gyrus.Conclusion Acupuncture combined with speech therapy could cause changes in activation patterns of the brain areas,which may contribute to the improvement of verbal ability of the aphasic patients.
