Ojo Vibration Method To Improve The Vertebral Artery Type Of Cervical Vertigo Induced By Experimental Study

Objective: To inquire into the effect and mechanism of GV₁₄ Vibrating manipulation for improving the cervical vertigo of Vertebral-arterial type of cervical spondylosis (VACS) and blood dynamics of experimental rabbits.Methods: 48 Japanese rabbits were randomly assigned to four groups, namely: manipulation group, Sibeline group, model control group, and blank control group (12 rabbits in each, with half of male and half female). While rabbits in the blank control group were injected with saline, all the other groups were injected by tissue sclerosing remedy-775 into the soft tissue on the left side of cervical vertebral transverse protuberance, which set up the VACS model. 7 weeks after injection, the manipulation group were given viberating treatment on GV₁₄ for 2 courses, and the Sibeline group were given Sibeline at 1.67g / Kg to affuse stomach, while no treatment was given to the 2 control groups. After 2 weeks of intervention, all the 4 groups were measured by ENG which is induced by vestibular single pendulum stimulation on the quadrupole swing, and TCD testing indexed by the systolic phase velocity (Vs), disatolic phase velocity (Vd) and mean velocity (Vm) of blood flow in the bilateral vertebral artery (VA) and basiar artery (BA).Results: The velocity in Basilar artery (VBA), vestibular blood supply and ENG frequency decreased, while viscosity of whole blood in high, middle and low shere increased in VACS models. The viberating manipulation can significantly improve ENG frequency, velocity in VBA and vestibular blood supply, however, no significant improvement was detected on blood viscosity. Sibeline can reduce the viscosity of whole blood and increased the Vs of BA, but was non-effective in improving the Vd and Vm of BA.Conclusion: The vibrating manipulation may enhance the impulse of blood flow at diastole phase in BA by relieving the resistance at the distal circulation of BA and reinforcing the compliance and diastolic-systolic action of BA. Vibrating manipulation's effects may depend upon activating the local microcirculation in the inner ear so as to recover the vestibular function and vestibulo-ocular reflex, while no significant effect on blood dynamics was observed.
