Two recent acupuncture studies have received some media attention, both purporting to show positive effects. Both studies are also not clinical efficacy trials, so cannot be used to support any claims for efficacy for acupuncture – although that is how they are often being presented in the media.
These and other studies show the dire need for more trained science journalists, or science blogging – they only make sense when put into a proper context. No media coverage I read bothered to do this.
The first study comes out of South Korea and involves using acupuncture in a rat model of spinal cord injury. The researchers used a standard method of inducing spinal cord injury in rats, and compared various acupuncture locations to no-acupuncture control. They followed a series of metabolic outcomes, as well as the extent of spinal cord injury and functional recovery. They conclude:
Thus, our results suggest that the neuroprotection by acupuncture may be partly mediated via inhibition of inflammation and microglial activation after SCI and acupuncture can be used as a potential therapeutic tool for treating acute spinal injury in human.
The notion that acupuncture will actually improve outcome after acute spinal cord injury is, of course, extraordinary. This goes far beyond a subjective decrease in pain or some other symptomatic benefit. Therefore similarly extraordinary evidence should be required to support such a claim – and this study does not provide that.
