ABSTRACT
Objective From the angle of electrophysiology, go further into the mechanism of action of acupuncture treatment to the insufficient blood-supply of vertebral basilar artery and at the same time, make a comparison of the effects between the acupuncture on cephalic meridian points and zonation cephalic acupuncture. Methods Through the contrast before and after adopting the self-acupuncture on the testees of 28 cases (including healthy persons of seven cases and TIA patients of 21 cases), observe the change of immediate effect of all waves latent period values of BAEP. Results The BAEP wave latent period of healthy persons (exclusive of I wave of auditory fainting region) assumes a relative delay within the physiological range and by comparison between points and region, the delay of V-wave Baihui point is evidently higher than that of auditory fainting region. However, the latent period of all waves of TIA patients is relatively moved up, especially there are evident differences before and after the I-wave acupuncture is carried out. Viewing from the comparison between points and region, there is no significant difference. Conclusion The function of acupuncture lies in the adjustment of antagonistic body state and it is most effective under the pathological state. Acupuncture will play the main role of excitation to the auditory nerve conduction of BAEP of TIA patients (from cochlea to midbrain) and the influence over the peripheral nerves is more sensitive than over the center ones. Although points and region have their own relative specificities, there is no significant difference between them.
