针刺对缺血性中风患者食指运动激活脑功能区的影响

Effects of acupuncture on the cortical functional areas activated by index finger motion in the patient with ischemic stroke

目的:观察针刺对运动状态下缺血性中风患者脑功能区的影响。方法:15例缺血性中风患者分别在基础和针刺状态下食指运动采集脑功能区功能性磁共振成像图像,测量激活的区域、大小及信号强度。结果:基础状态下食指运动可见对侧初级运动区、运动前区以及第一感觉区的激活,针刺状态下食指运动除见上述区域激活外,还可见同侧初级运动区,病灶部位及对侧顶上小叶、颞上回、岛叶等部位的激活。针刺状态下激活面积及最小信号强度方面均大于基础状态。结论:针刺对缺血性中风的康复与改善大脑皮层功能区血液循环有关。

Objective To observe the effect of acupuncture on cortical functional areas of the patient with ischemic stroke activated by the index finger motion. Methods The cortical magnetic resonance imaging （fMRI） were carried out in 15 cases of ischemic stroke during the index finger motion at acupuncture or non-acupuncture. The distribution of the cortical functional areas activated and the size of the activated region and the intension of signals were measured. Results The finger motion with no acupuncture could activate the contralateral primary somatomotor area （M1）, contralateral premotor area （PMA） and contralateral first somatosensory area （$1）. The finger motion with acupuncture could activate the same areas and also activate ipsilateral M1, focus area contralateral superior parietal lobule, contralateral superior temporal gyrus, and contralateral insular lobe, etc.. Both the area of the acti vated region and the minimum signal in the finger motion with acupuncture were statistically significantly larger than those in finger motion with no acupuncture. Conclusion Rehabilitation of motor functions of the patient with ischemic stroke by acupuncture is related with improvement of blood circulation functional area in the cortex.
