Objective To study the data variations in Transcranial Doppler Ultrasound ( TCD) and vertigo scale on vertebra-basilar insufficient vertigo ( VBIV ) under treatments of electrical stimulus of simulated-brain wave ( ESSBW ) coordinating with traction, and discuss on the mechanism .Methods Forty-four patients with VBIV were randomly divided into two groups .Comprehensive group was given ESSBW coordinating with traction;traction control group was given only traction.Before the treatments and two weeks later , the patients were estimated by TCD and vertigo scale to observe the effects on blood flowing rate and functional status of VBIV patients .Results Effective rate of comprehensive group (63.3%) and traction group (7.1%) had a significant difference ( P <0.01).After the treatments, the blood flowing speeds of two sides vertebral arteries and basilar artery of the two groups were all increased distinctly .Compared with traction group , the comprehensive group was preceded characterizing with a more significant clinical efficacy ( P <0.05).Conclusion It could promote the blood flowing speeds of two sides vertebral arteries and basilar artery under the treatments of ESSBW coordinating with traction.%目的：观察脑电仿生电刺激配合牵引治疗椎基底动脉供血不足性眩晕（ VBIV ）的经颅多普勒超声（TCD）和眩晕量表评估的变化，探讨脑电仿生电刺激配合牵引治疗椎基底动脉供血不足性眩晕的作用机制。方法将44例VBIV患者，随机分为脑仿生电刺激配合牵引治疗组（综合组）和牵引对照组（牵引组）。治疗前及治疗2疗程后检查TCD并进行眩晕量表的评估，观察脑电仿生刺激配合牵引治疗对VBIV患者血流速度及患者症状与功能状况的影响。结果综合组显效率为63．3％，牵引组显效率为7．1％。2组显效率比较，差异有统计学意义（ P ＜0．01）；治疗后较治疗前，综合组与牵引组双侧椎动脉和基底动脉收缩期颅内血流峰速均有明显提高（ P ＜0．05），综合组优于牵引组，差异有统计学意义（ P ＜0．05）。结论脑电仿生电刺激配合牵引治疗VBIV可改善该类型颈椎病的双侧椎动脉和基底动脉收缩期血流峰速度，临床疗效较显著。
