A detailed study done by scientists in Denmark have a good and bad news: to treat pain, acupuncture works even - but very little.
The research is called meta-analysis, "effort in which a group of scientists brings together the best in previous clinical trials, made by independent groups, hoping to discover what in fact is true in all of them. This type of study is what gets more respect from the doctors, just to try to eliminate any bias from observation of one group or another and get a larger database.
In this case, the researchers collected data from 13 different clinical trials, made in the treatment of several types of pain - from enchaqueca to postoperative pain, through colonoscopy and osteoarthritis, among others. In total, over 3,000 people attending these tests.
The volunteers were divided into three groups: one that received no extra treatment for pain, one that received what the scientists call "acupuncture-placebo" (an acupuncturist stick needles in the patient, but not in the places indicated by the traditional Chinese medicine) and a fact which was treated with acupuncture, using all the correct requirements.
Then, the patients assessed the pain on a scale from 0 to 100. The average of all studies, the difference in pain between those who received traditional acupuncture and placebo acupuncture was only 4 points. On this scale, the minimum considered to give clinical relevance is 10 points.
"A small analgesic effect of acupuncture was found, which appears not to have clinical relevance," say the researchers of the Nordic Cochrane Center in Copenhagen, in an article published in the latest issue of medical journal "British Medical Journal."
Something happens
The most curious, however, was that, although the difference between true acupuncture for your version placebo were almost irrelevant, both played significant analgesic effect compared to the absence of treatment for pain - the difference between the placebo and the lack of acupuncture treatment was 10 points, on a scale from 0 to 100 for pain.
That is perhaps the least important in acupuncture is the local body where the needle stick, plus the fact that they are being stick. It is suggested that Adrian White, Mike Cummings, of Medical Acupuncture Society British, in comments published in the same edition of the BMJ. " They suggest that acupuncture seems, at least in part, using neurological routes in common with placebo for analgesia, and that the study can offer them sparkle as important in improving medical care.
But the prospect of having any effect, beyond the psychological, in the treatment of pain with acupuncture, has yet to be answered by future research. "If they stick needles into acupuncture points, or anywhere, or do not reduce the pain regardless of the psychological impact of the ritual of treatment is not yet clear," write the scientists led by Asbjørn Hróbjartsson of the Nordic Cochrane Center.
