Abstract:
Objective To study the effect of the neck rotation and lateral bending on the vertebral artery blood flow, and to analyze the relationship between the artery blood flow and cervical vertigo. Methods Thirty patients with cervical vertigo were studied with exclusion of auditory vertigo and severe cardio-cerebrovascular disease, which involved 18 males and 12 females, whose average age was 52.13 years with a range of 42-73 years. They all had cervical degenerative change in different degree and neck-shoulder-back pain history. The study also included 15 volunteers without vertigo, 8 males and 7 females, the average age was 49.47 years with range, 38-70 years, they also had some cervical degenerative change. They were selected to detect the blood flow of bilateral intracranial segments of the vertebral arteries using TCD with the neck in neutral, bilateral rotation 15?,30?,45?,60? and bilateral bending. Results In neutral position, vertebral artery blood flow was lower in study group than in control(P
