acupuncture and migraines

It is easy to ridicule a 2000-year-old treatment that can seem closer to magic than to science. Indeed, from the 1970s to around 2005, the skeptic’s point of view was understandable, because the scientific evidence to show that acupuncture worked, and why, was weak, and clinical trials were small and of poor quality.

But things have changed since then. A lot.

Thanks to the development of valid placebo controls (for example, a retractable “sham” device that looks like an acupuncture needle but does not penetrate the skin), and the publication of several large and well-designed clinical trials in the last decade, we have the start of a solid foundation for truly understanding the effectiveness of acupuncture.

Individual large-scale clinical studies have consistently demonstrated that acupuncture provided better pain relief compared with usual care. However, most studies also showed little difference between real and sham (fake) acupuncture. In order to address this concern, a 2012 meta-analysis combined data from roughly 18,000 individual patients in 23 high-quality randomized controlled trials of acupuncture for common pain conditions. This analysis conclusively demonstrated that acupuncture is superior to sham for low back pain, headache, and osteoarthritis, and improvements seen were similar to that of other widely used non-opiate pain relievers.

How do we know if acupuncture really works for pain?

And the safety profile of acupuncture is excellent, with very few adverse events when performed by a trained practitioner. Meanwhile, basic science studies of acupuncture involving animals and humans have shown other potential benefits, from lowering blood pressure to long-lasting improvements in brain function. More broadly, acupuncture research has resulted in a number of insights and advances in biomedicine, with applications beyond the field of acupuncture itself.
