Objective: To compare the effect differences of acupuncture of dredging the governor vessel (GV) and conception vessel (CV) for cervical vertigo with deficiency of qi and blood so as to provide Objective evaluation and guide for clinical treatment.
Methods: A total of 60 patients were randomly divided assigned into an observation group and a control group, 30 cases in each one. The acupoints of the observation group were mainly in the GV, namely Shenting (GV 24), Baihui (GV 20), Fengfu (GV 16), Dazhui (GV 14), Shenzhu (GV 12), Jiaji (EX-B 2) of C6 and C7, Zusanli (ST 36) and Sanyinjiao (SP 6). The acupoints of the control group were mainly in the CV, including Danzhong (CV 17), Zhongwan (CV 12), Xiawan (CV 10), Guanyan (CV 4), Qihai (CV 6), Jiaji (EX-B 2) of C6 and C7, Zusanli (ST 36) and Sanyinjiao (SP 6). Acupuncture was given once every other day and 10 treatments were taken as one course. After 2-course treatment, the changes before and after treatment of the scores of symptoms of cervical vertigo and functional evaluation scale, the scores of symptoms of deficiency of qi and blood, the mean blood flow rate of vertebral-basilar artery were observed. Also, the effects were evaluated.
Results: (1) The cured and effective rate and total effective rate of the observation group were 76.7% (23/30) and 93.3% (28/30), which were better than 46.7% (14/30) and 70.0% (21/30) of the control group (both P<0.05). (2) As for the scores of symptoms of cervical vertigo and functional evaluation scale and the mean blood flow rate, the results were obviously improved after treatment in the two groups (all P<0.05), with superiority in the observation group (all P<0.01). (3) After treatment,the scores of the symptoms of deficiency of qi and blood were decreased obviously in the two groups (all P<0.05). As to fatigue,facial expression,tongue and pulse condition,there was no statistical significance between the two groups after treatment (all P>0.05),but treatment for palpitation and shortness of breath achieved better effect in the control group(P<0.01).
Conclusions: The effect of dredging the GV for cervical vertigo with deficiency of qi and blood is superior to that of acupuncture mainly in the CV,which can improve the symptoms of cervical vertigo and the mean blood flow rate of vertebral-besilar better. But acupuncture at acupoints both in the GV and CV may be better for the patients with syndrome of deficiency of qi and blood seriously.
