旋转手法对椎动脉血流平均速度的影响

目的　观察手法治疗椎动脉型颈椎病的经颅多普勒 (TCD)变化 ,从血流动力学角度探讨手法治疗的作用机制。方法　将 82例椎动脉型颈椎病患者随机分成手法治疗组 4 0例与常规治疗组 4 2例 ,治疗前及治疗后检查TCD ,观察手法治疗对椎动脉型颈椎病患者的血流平均速度的影响。结果　① 82例患者治疗前椎基底动脉血流平均速度均明显低于正常参考值范围(P <0 .0 5 )。TCD异常率为 76 % ( 6 2 /82 )。②治疗后两组椎基底动脉血流速度均有改善。手法治疗组比常规治疗组椎动脉血流速度改善更明显 (P <0 .0 5 )。结论　手法治疗可以改善椎动脉型颈椎病椎基底动脉的血流速度。

Effect of rolling manual reduction on mean blood velocity of vertebral artery

Objective It is to observe the effect of manual reduction on vertebral artery type cervical spondylosis patients with transcranial Doppler (TCD) and probe its mechanism. Methods Eighty two patients with vertebral artery type cervical spondylosis were divided into manual reduction treatment group and routine treatment group. All were examined with TCD before and after treatment. The effect of manual reduction on the mean blood velocity was analyzed base on the changes revealed by TCD. Results Mean blood velocities of vertebrobasilar artery (VBA) in eighty two patients were significantly lower than normal before treatment ( P <0.05). Abnormality rate of TCD was 76%. The blood velocity in all patients increased and that in manual reduction treatment group was prior to that in routine treatment group ( P <0.05). Conclusion Manual reduction can improve the blood velocity of VBA in patients with vertebral artery type cervical spondylosis.
