Objective: To observe the therapeutic effect of 5-step manipulation and traction of cervical vertebrae on vertebroarterial type of cervical spondylosis and probe its mechanism. Methods: The 120 patients were randomly divided into a treatment group (manipulation group) and a control group (traction group) with 60 cases in each. The curative effects in the two groups were evaluated after treatment. Results: The curative rate and the total effective rate is 26.7% and 93.4% respectively in the treatment group, and 13.3% and 86.7% respectively in the control group, with statistical significance in the total effective rate of the two groups (P<0.05). Conclusion: Manipulation and traction of cervical vertebrae can effectively improve the clinical symptoms of vetebroarterical type of cervical spondylosis with a good therapeutic effect.
