Abstract:Objective: To study the possible mechanism of traction and massage to improve cerebral vessels function in cervicogenic headache (CH). Method: Transcranial doppler sonography (TCD) was performed to explore the intracranial segments of internal carotid artery (cerebral anterior, middle and posterior arteries), bilateral vertebral arteries, and basilar artery in 125 CH cases and 90 healthy adults before and after physical treatment. Result:1. In the total tested 125 cases of CH group, after treatment, the mean velocity of blood flow (Vm) of cerebral anterior and middle arteries decreased to normal value of control group(P<0.05). 2. The abnormality ratio and average values of the antisymmetry index(AI)which represents the intracranial paired arteries Vm disparity were significantly decreased after treatment in CH group compared with those before treatment and the control group (P<0.01). Conclusion: The treatment of traction and massage possesses bidirectional regulating effects on the cerebral blood circulation, there by reduces the headache attacks in CH patients.
