Acupuncture Shown to Aid Pain Managment
Posted: September 3, 2009
A new study has shown the acupuncture helps regulate key pain receptors in the brain, furthering its range of uses in therapeutic treatments.
Traditional Chinese acupuncture, increasingly popular in the West for a variety of ills, eases pain by regulating key receptors in the brain, according to a new study. The study showed that acupuncture increases the binding availability of mu-opioid receptors in regions of the brain that process and weaken pain signals—specifically the cingulate, insula, caudate, thalamus and amygdala. By directly stimulating these chemicals, acupuncture can affect the brain's long-term ability to regulate pain, the study found. A report on the findings is in the September issue of NeuroImage.
Using positron emission tomography scans of the brain, the researchers examined 20 women with fibromyalgia, a chronic pain condition. The women took no new medications for their pain during the study period.
"The increased binding availability of these receptors was associated with reductions in pain," Richard Harris, a researcher at the University of Michigan's Chronic Pain and Fatigue Research Center and a research assistant professor of anesthesiology at the University of Michigan Medical School, said in a news release from the university.
What's more, Harris said, the findings could prompt doctors to use morphine and other opioid drugs with greater pain-killing effectiveness after treatment with acupuncture because those drugs bind to the same receptors.
