Effect of vertebral manipulation therapy on vertebro-basilar artery blood flow in cervical spondylosis of vertebral artery type / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of vertebral manipulation (VM) therapy on vertebro-basilar artery (VBA) blood flow in patients with cervical spondylosis of vertebral artery type (CS-VAT) by transcranial Doppler (TCD) ultrasonic examination.</p><p><b>METHODS</b>One hundred and fifty patients with CS-VAT were randomized into the VM group (n = 100) and the acupuncture group (n = 50), and treated for ten times as one therapeutic course. Changes of the contraction peak, the end-diastolic and average blood flow velocity of VBA before and after treatment in the two groups were observed and compared by TCD.</p><p><b>RESULTS</b>Vp, Vd, Vm of LVA, RVA and BA in the two groups after treatment were all lowered, showing significant difference, excepting Vp of VBA in the acupuncture group, when compared with before treatment (P< 0.05 or P <0.01). Comparison between the two groups after treatment showed significant difference in Vp and Vm of LVA, Vp, Vd and Vm of RVA, Vp and Vm of VBA respectively (P<0.05, P <0.01).</p><p><b>CONCLUSION</b>VM therapy in treating patients with CS-VAT shows therapeutic effect superior to VA therapy, which could significantly improve VBA blood flow.</p>
