通元针法治疗带状疱疹后神经痛:随机对照试验OA

Objective To observe the clinical efficacy of Tongyuan acupuncture in treatment of postherpetic neuralgia(PHN).Methods A total of 106 patients with PHN were randomly divided into a Tongyuan electroacupuncture group(53 cases,3 cases dropped out)and a conventional electroacupuncture group(53 cases,4 cases dropped out,2 cases were eliminated).In the Tongyuan electroacupuncture group,Baihui(GV20),Yintang(GV24+),Shuigou(GV26),Qihai(CV6),Guanyuan(CV4),ashi points and bilateral Xinshu(BL15),Geshu(BL17),Ganshu(BL18),Pishu(BL20),Tianshu(ST25)were selected,and 5 to 6 pairs of acupoints were selected to connect the electroacupuncture therapeutic apparatus;in the conventional electroacupuncture group,ashi points and Jiaji points(EX-B2)of the relevant ganglion segments in the affected area were selected,and Jiaji points(EX-B2)and ashi points were connected to the electroacupuncture therapeutic apparatus.In both groups,dense-disperse waves were selected at a frequency of 2 Hz/100 Hz and a current of 2 mA.The needles were retained for 30 min per session,once daily.Five sessions constituted one treatment course,with a 2-day interval between courses.A total of four treatment courses were administered.The simplified McGill pain questionnaire(SF-MPQ)score(including the pain rating index[PRI]score,visual analogue scale[VAS]score,and present pain intensity[PPI]score)of both groups were observed before treatment,after 2 weeks of treatment,and after 4 weeks of treatment.The Pittsburgh sleep quality index(PSQI)score,Hamilton anxiety scale(HAMA)score,and Hamilton depression scale(HAMD)score of both groups were observed before treatment and after 4 weeks of treatment.Clinical efficacy was evaluated after treatment,and pain recurrence was followed up at 3 months after treatment completion.Results Compared with before treatment,the sub-scores and total scores of the SF-MPQ in both groups decreased after 2 and 4 weeks of treatment(P<0.05),and the scores after 4 weeks of treatment were lower than those after 2 weeks of treatment(P<0.05).After 2 weeks of treatment,the scores of VAS and PPI,and the total score of SF-MPQ in the Tongyuan electroacupuncture group were lower than those in the conventional electroacupuncture group(P<0.05).After 4 weeks of treatment,all sub-scores and total score of the SF-MPQ in the Tongyuan electroacupuncture group were lower than those in the conventional electroacupuncture group(P<0.05).After treatment,the PSQI,HAMA,and HAMD scores in both groups were lower than those before treatment(P<0.05);the PSQI,HAMA,and HAMD scores in the Tongyuan electroacupuncture group were lower than those in the conventional electroacupuncture group(P<0.05).The total effective rate and marked effective rate in the Tongyuan electroacupuncture group were 90.0％(45/50)and 72.0％(36/50),respectively,both higher than those in the conventional electroacupuncture group(74.5％[35/47]and 44.7％[21/47],P<0.05).During follow-up,the pain recurrence rate in the Tongyuan electroacupuncture group was 2.2％(1/45),which was lower than that in the conventional electroacupuncture group(17.1％[6/35],P<0.05).Conclusion Tongyuan acupuncture can alleviate pain,improve sleep disturbances,and ameliorate emotional comorbidities in patients with PHN,and its short-term and long-term efficacy is superior to that of conventional electroacupuncture.
