[Penetrating needling on head points for vertigo caused by vertebral-basilar arterial blood-supply insufficiency].

OBJECTIVE

To observe the differences in therapeutic effect between penetrating needling on head points and acupuncture of syndrome division in the treatment of vertigo caused by vertebral-basilar arterial blood-supply insufficiency.

METHODS

Sixty cases of vertigo caused by vertebral-basilar arterial blood-supply insufficiency were divided into 2 groups: a penetrating needling on head points group (group A) and an acupuncture of syndrome division group (group B), 30 cases in each one. In group A, penetrating needling technique was applied from Baihui (GV 20) towards Qianding (GV 21), Shuaigu (GB 8) towards Qubin (GB 7) and Yuzhen (BL 9) towards Tianzhu (BL 10). Electric stimulation was added. In group B, the acupoints were selected according to syndromes. For example, upper disturbance of wind yang: Ganshu (BL 18), Xingjian (LR 2),etc. were selected; upper disturbance of turbid phlegm: Yinlingquan (SP 9), Fenglong (ST 40), etc. were selected; qi and blood deficiency: Baihui (GV 20), Xuehai (SP 10), etc. were selected; liver and kidney yin deficiency: Ganshu (BL 18), Shenshu (BL 23), etc. were selected. Electric stimulation and needling manipulation were conducted on those acupoints. Ten treatments made one session. After continuous 2 sessions of treatment, the efficacy, symptom score and physical sign score were compared between two groups. Transcranial Doppler (TCD) examination was done to observe hemodynamic changes of anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA) before and after treatment.

RESULTS

The total effective rate in group A was 96.7% (29/30) that was obviously better than 83.3% (25/30) in group B (P<0.05). The scores of vertigo degree, vertigo frequency, duration and accompanied symptoms after treatment were lower obviously as compared with those before treatment in two groups (all P<0.05). The improvements in group A were much significant (all P<0.05). The highest mean velocity(Vm) of bilateral MCA, ACA and PCA were apparently reduced after treatment in two groups (P< 0.05, P<0.01). The improvements in group A were much more apparently (all P<0.05).

CONCLUSION

The penetrating needling on head points can effectively relieve vertigo caused by vertebral-basilar arterial blood-supply insufficiency, reduce the attack frequency and improve in its accompanied symptoms. Its clinical efficacy is significantly superior to that in acupuncture of syndrome division group.
