Clinical Observation of Mild Moxibustion at Fengchi (GB20) for Cervical Spondylosis of Vertebral Artery Type / 上海针灸杂志

ABSTRACT

Objective To observe the clinical efficacy of mild moxibustion at bilateral Fengchi (GB20) in treating vertigo due to cervical spondylosis of vertebral artery type, and its effect on the blood flow of vertebral artery.Method A total of 103 eligible patients with cervical spondylosis of vertebral artery type were randomized into two groups. Patients in the observation group were intervened by mild moxibustion at bilateral Fengchi; the control group was given oral administration of Nimodipine. The blood flow velocity was compared before and after the treatment, and the clinical efficacies of the two groups were compared.Result After the treatment, the systolic velocity (Vs) (left vertebral artery, LVA; right vertebral artery, RVA), mean velocity (Vm) (LVA, RVA) and diastolic velocity (LVA, RVA) of the observation group were better than those of the control group, and the differences were statistically significant (P<0.05); at the end of the intervention and 3 months after, the Dizziness Assessment Rating Scale (DARS) scores of the observation group were significantly lower than those of the control group (P<0.05); at the end of the intervention, the markedly effective rate was 80.0% in the observation group versus 62.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Mild moxibustion at bilateral Fengchi can improve the blood flow of vertebral artery in patients with cervical spondylosis of vertebral artery type, and produce a significant efficacy.
