[Clinical observation on treatment of PC-BPPV by dynamic and static acupuncture method combined with manual...

To observe the clinical effect and advantages of dynamic and static acupuncture method combined with manual reduction on posterior semicircular canal benign paroxysmal positional vertigo (PC-BPPV).

Ninety patients with PC-BPPV who met the inclusion criteria were randomly divided into manual reduction control group, acupuncture control group and experimental group, with 30 cases in each group. Epley reduction method was used for manual reduction control treatment of patients in the manual reduction control group, until there was no obvious vertigo of patients. Patients in the acupuncture control group received ordinary acupuncture treatment, while patients in the experiment group received dynamic and static acupuncture treatment, both on the basis of manual reduction control treatment. Baihui(GV20) and Yintang(GV24⁺), Sanyinjiao(SP6), Zhongzhu(TE3), Houxi(SI3) and Waiguan(TE5) on the healthy side, and the vertigo-auditory area and Fengchi(GB20) on the affected side were selected for acupuncture intervention, which was performed once a day, with needles retained for 30 minutes in two acupuncture groups. Every six times was taken as a session and two sessions were required. Dizziness handicap inventory (DHI) scale and visual analogue score (VAS) were used to evaluate the degree of vertigo before, after 1 and 2 sessions of treatment respectively.

Compared with those before treatment, the DHI score and VAS score of each group after 1 and 2 sessions of treatment were both significantly decreased (P<0.05). Compared with the acupuncture control group and the manual reduction control group, the DHI score of the experiment group was significantly decreased (P<0.05) after 1 and 2 sessions of treatment. VAS score of the experiment group was significantly decreased compared with that of the manual reduction control group(P<0.05) after 1 and 2 sessions of treatment. The total effective rate of the experiment group was 86.67%, better than those of the acupuncture control group (83.33%, P<0.05) and the manual reduction control group(66.67%, P<0.05).

The dynamic and static acupuncture method combined with manual reduction effectively improved vertigo symptoms in PC-BPPV with rapid and lasting effects, which is worthy of further clinical promotion and application.
