The claim that sticking needles in your head helps relieve migraines has long been debated by experts. And now a new study published in the Canadian Medical Association Journal may bring us one step closer to figuring out the truth.

For the study, researchers had 500 adults treated with either traditional Chinese acupuncture or a fake treatment (in which acupuncture needles were inserted in nonspecific points).

Prior to the study, most suffered monthly migraines, on average six days of migraines a month. After completing the study, all of the participants reported fewer days with migraines than before the study began, along with improvements in the frequency and intensity of migraines. However, lasting effects were seen only in study participants who received traditional acupuncture.

Experts believe that compared to previous research, these findings could indicate that people who respond best to acupuncture are those who have not been helped by other treatments and those who had past positive experiences with acupuncture.
