OBJECTIVE:To investigate the effectiveness of electroacupuncture at Jiaji acupoints (EX-B 2) plus moxibustion and intermediate frequency on postherpetic neuralgia (PHN).METHODS:A total of 140 outpatients who satisfied the inclusion criteria and volunteered for this treatment were randomly divided into treatment (n =70) and control (n =70) groups.Both groups received a localized lesion area and electroacupuncture treatment combined with moxibustion and intermediate frequency.The treatment group (TG) increased acupuncture at Jiaji acupoints (EX-B 2) and electroacupuncture.Pain and anxiety were assessed before and after 5,10,15,and 20 treatments by using visual pain simulation score (VAS) and Hamilton anxiety scale (HAMA),respectively.Clinical efficacy was also evaluated.RESULTS:The baseline between the two groups did not significantly differ (P ＞ 0.05).The VAS and HAMA scores of the two groups after treatment significantly decreased compared with those of various treatment stages (P ＞ 0.05).The HAMA score (P ＜ 0.01) of TG was lower than that of the control group (CG).The VAS score of TG was lower than that of CG in the 5th and 10th treatments (P ＜ 0.01).In the 15th and 10th scores,CG was also superior to TG (P ＜ 0.05).CONCLUSION:The combined treatment of electroacupuncture at Jiaji acupoints (EX-B 2),moxibustion,and intermediate frequency can relieve the pain and anxiety symptoms of PHN.The efficacy of the combined treatment was superior to traditional acupuncture.
