Abstract

ALLAIS and COLLEAGUES, Department of Gynecology and Obstetrics, Women's Headache Center, University of Turin, Via Ventimiglia 3, 10126 Turin, Italy. gb.allais@tiscali.it  sought to identify the location of the most therapeutic ear acupoints effective for migraine pain.

Background

Ear acupuncture can be a useful mean for controlling migraine pain. It has been shown that a technique called the Needle Contact Test (NCT) can identify the most efficacious ear acupoints for reducing current migraine pain through just a few seconds of needle contact.

Methodology

The majority of the points were located on the antero-internal part of the antitragus (area M) on the same side of pain. The aim of this study was to verify the therapeutic value of area M and to compare it with an area of the ear (representation of the sciatic nerve, area S) which probably does not have a therapeutic effect on migraine attacks. We studied 94 females suffering from migraine without aura, diagnosed according to the ICHD-II criteria, during the attack. They were randomly subdivided into two groups: in group A, tender points located in area M, positive to NCT were inserted; in group B, the unsuitable area (S) was treated. Changes in pain intensity were measured using a VAS scale at various times of the study.

Results

During treatment, there was a highly significant trend in the reduction of the VAS value in group A (Anova for repeated measures: p<0.001), whereas no significance was observed in group B. VAS values were significantly lower in group A than in group B at 10, 30, 60 and 120min after needle insertion.

Conclusion

This study suggests that the therapeutic specificity of auricular points exists and is linked to the somatotopic representation of our body on the ear.
