This study was performed to review clinical research studies involving acupuncture treatment for primary headache disorders to provide a basic reference for future studies. Clinical studies of primary headache disorders treated with acupuncture were retrieved from 3 Korean electronic databases (NDSL, OASIS, and RISS). The studies were classified by year of publication, type of study, type of acupuncture, outlined acupoints, methods used for filiform needles, pharmacopuncture, auricular acupuncture, and thread-embedding acupuncture. Thirty-eight trials were reviewed, of which 33 used filiform needles, 6 pharmacopuncture, 1 auricular acupuncture, and 1used thread-embedding. Most of the studies reported that acupuncture treatment was effective in treating primary headache disorders. Some studies reported statistically significant effects, but the results overall were inconsistent. Therefore, there is insufficient evidence to support the treatment of acupuncture to resolve headaches. On the basis of these results, further studies should be performed to qualitatively and quantitatively determine the efficacy of acupuncture treatment for primary headache disorders.
