Summary

Background

In this study we investigated the neurolinguistic and neuroimaging characteristics of post-stroke motor aphasia patients. The effects of acupuncture on cortex activation by using magnetic resonance imaging (MRI) in patients with motor aphasia were also studied.

Methods

In this study 43 patients with motor aphasia after stroke were assessed according to Clinical Rehabilitation Research Center aphasia examination (CRRCAE) for linguistic evaluation and MRI and computed tomography (CT) were used for the analyses of brain lesions. The MRI imaging data were also examined using statistical parametric mapping (SPM8) software. Cortex activation images during acupuncture were analyzed using generalized linear model analysis.

Results

The results of MRI and CT showed diverse brain lesion regions of post-stroke motor aphasia including the cortex, subcortex and cortex together with the subcortex. The language-related brain areas are activated by acupuncture including frontal, temporal, parietal and occipital lobes as well as insula, precuneus and other wide range of brain function areas as shown by MRI.

Conclusions

Our study showed that the brain lesion regions in post-stroke motor aphasia were not completely consistent with the classical motor speech center. By using MRI our study results suggest that the formation of cognitive language may be involved with the cortical-subcortical functional networks. Acupuncture may be useful for treatment of motor aphasia after stroke.
