A study has shown that acupuncture provides more relief for lower back pain than other medications or physiotherapy, reported The Daily Telegraph and other newspapers. Treatment using the “ancient Chinese technique of acupuncture is better at reducing back pain than more conventional treatments”, The Telegraph said. The newspapers said that even sham or fake acupuncture, where needles are put into the wrong places, has been shown to be almost as effective. The Times said: "The results indicate that both acupuncture and sham acupuncture act as powerful versions of the placebo effect.”
The reports are based on a German study of chronic back pain where conventional treatments were compared with true and fake acupuncture. The study findings are in contrast to those of other studies and systematic reviews in this area and highlight a need for further long-term research into acupuncture as an alternative therapy to verify these findings.
This study was conducted by Dr Michael Haake and colleagues of University of Regensburg, Philipps-University Marburg, Ruhr-University Bochum, and Centre for Clinical Acupuncture and Research, in Germany. The study received funding from German public health insurance companies and it was published in the peer-reviewed medical journal Archives of Internal Medicine.
This was a double blind randomised controlled trial to compare true and fake acupuncture with conventional treatment for patients with chronic lower back pain.
This multicentre trial involved 1,162 patients who suffered from chronic back pain for over six months (average time eight years), and had not had previous acupuncture treatment. Practitioners in 340 different outpatient settings performed the acupuncture. The patients received ten 30 minute sessions, twice a week, and an additional five sessions if required, of either:
Telephone interviews were conducted at six weeks, three months and six months to determine the response to treatment. Neither the patient nor the person interviewing was aware of which treatment the patient had received.
At six months of follow-up 47.6% people in the true acupuncture group responded to treatment, reporting a marked reduction in pain. In the fake acupuncture group 44.2% responded and in the conventional treatment group 27.4% responded. There was no difference in rates of bad side effects of treatment between any of the groups.
The researchers concluded that acupuncture was superior to conventional treatment, with about double the response rate. This was the case whether true or fake acupuncture was used. They say that this suggests that the emphasis on learning traditional Chinese acupuncture points may be unnecessary. They conclude that acupuncture gives “a strong therapy alternative to … conventional therapy”.
This trial seems to support the role of acupuncture as an effective alternative therapy for chronic lower back pain. There are some points to consider when interpreting the conclusions:
This study highlights the need for further examination into the use of acupuncture for chronic back pain. It will be important to try to tease apart the real treatment effects from those that occur through the placebo effect (the perceived improvement to health not attributable to a treatment). This information will then help guide the use of particular acupuncture techniques.
This is a subject which is of endless fascination to researchers. The complementary and alternative medicine section of the National Library for Health has 23 papers, many of them not single studies but reviews of multiple studies.
The evidence? There is still not universal agreement but acupuncture is very low risk and many people report significant benefit.
