BackgroundThere were numerous studies using acupuncture for pain relief and in most, the effect of this technique on preventing migraine attacks has been investigated. In those several studies that surveyed the effect of acupuncture on treatment of migraine headaches, the conclusion was not completely persuaded and they suggested further researches on this topic.ObjectivesThe purpose of this study is to examine the effect of acupuncture on controlling acute migraine attacks.MethodsThis study was a single blinded randomized clinical trial that was conducted on patients with a diagnosis of acute migraine attacks. At the time of reference, the patient’s pain intensity was measured and recorded in a written checklist. Acupuncture was done in the intervention group with thin metallic needles, which enter certain points in the ear’s skin; including shen men, autonomic, thalamus, frontal, and temple. In the placebo group, similar needles were used, however, they were inserted into unusual points. Thereafter, in 30 minutes, one, two, and four hours after the treatment, the pain intensity was also asked and compared with the reference time’s score.ResultsA total of 60 patients with the mean age of 31.4 ± 7.6 years were enrolled and 83.3% of them were women. There was no significant difference between two groups in terms of the baseline characteristics of participants including age, sex and pain duration before admission (P > 0.05). According to the results, there was a significant difference between the two groups on the checkpoints of 15, 30, 45, and 60 minutes after acupuncture (P < 0.05); however, the pain scores were not statistically different between the two groups on two, three, and four hours after intervention (P > 0.05).ConclusionsBased on the findings of our study, although the pain score was lower in the intervention group than the control group during first hour after the acupuncture, there was no significant change in pain score thereafter. Comparison of the two groups showed no differences between acupuncture and placebo acupuncture on decreasing the mean pain score.
