Abstract

Objectives This study is designed to verify the effectiveness of electroacupuncture (EA) on both side acupuncture point GB12, GB20 for chronic tension type headache (CTTH). Methods Subjects aged 18-65 years who had suffered from CTTH for more than 3months were recruited from September 2016 to May 2017. Thirty subjects were voluntarily recruited and they were randomly divided into 2 groups; 15 to EA group, another 15 to sham-EA group. The treatment sessions were performed every 2-4 days for a total of three sessions over 1 week. The symptoms of headache were assessed before the treatment and after a week from the last treatment by visual analogue scale (VAS), headache frequency (HF), Korean Headache Impact Test-6 (KHIT-6). Demographic characteristics of all participants were compared between the groups upon using chi-square test. Wilcoxon signed rank test was used to evaluate the values between baseline and follow-up. Wilcoxon rank sum test was performed to evaluate the differences between groups. p-values less than 0.05 were considered as significant. Results Before and after the intervention, no difference in VAS and KHIT-6 was observed between groups. HF of EA group decreased significantly compared with that of sham-EA group. Within the EA group VAS, HF and KHIT-6 decreased significantly after the treatment. Meanwhile, only KHIT-6 decreased significantly after the treatment in sham-EA group. Conclusions This study suggests that EA on both side acupuncture point GB12 and GB20 is applicable to improve symptoms in patients with CTTH.
