Feeding 9 Billion: Innovations in Agricultural Modeling
Acupuncture is one of the complementary medicines that is frequently used. A group of Canadian-led Cochrane Review Authors completed a systematic review of the research literature to see whether there is evidence that it works.
They found 10 trials, with a total of 661 participants, which investigated whether acupuncture alleviated neck pain. In nine of the trials, participants had suffered neck pain for three or more months, while one included people who had had pain for at least six weeks.
To assess whether acupuncture reduces pain at all, some trials compared acupuncture with “sham” or “placebo” treatments. In other trials, the researchers were trying to see how well acupuncture worked compared to another treatment.
Overall, people who received acupuncture reported better pain relief immediately after treatment than those who received sham treatments such as TENS or laser that had the machines switched off, or acupuncture with the needles inserted in the wrong place. People who had acupuncture also reported that their pain went away to a greater extent than those who were just on a list waiting for treatment. In one small trial, people who received acupuncture reported better pain relief in the short-term than those who received massage therapy. There were no serious side effects reported in any of these trials.
“What we need now are some trials that include greater numbers of people and look at the long-term effect of the treatment,” says lead Review Author Dr Kien Trinh who works in McMaster University, Hamilton, Canada.
