Conclusion
Finally, it has to be emphasized that this study says nothing about acupuncture itself, except for providing a possible mechanism for a non-specific local response. The term “acupuncture”, in fact, is becoming increasingly problematic and is confusing the scientific literature, not to mention the public. What is acupuncture? If we use the term broadly enough to mean any use of needles, with or without electrical stimulation, at any points, with or without skin penetration, etc. then the term is too broad to be useful. If we use the term narrowly – to mean sticking needles to a certain depth in specific acupuncture points that work through a novel mechanism specific to those locations, then we can say, based upon extensive research, that “acupuncture” does not work and its proposed underlying mechanisms are nothing more than pre-scientific superstition.
This study is an excellent example of the mischief caused by confusing the non-specific use of the term “acupuncture” with its more traditional use. Research involving acupuncture in its vaguest sense is used to promote “acupuncture” in the traditional sense. This is highly deceptive and scientifically sloppy.
The researchers of this current study could have used other controls to see if the effect they discovered is in any way specific to any acupuncture variables. For example – they could have used a non-acupuncture point as a control, or other forms of mechanical pain production that do not involve needles. I suspect any local pain production or mechanical trauma beyond a certain threshold would result in the same adenosine response – which certainly seems like a non-specific mechanism to modulate pain.
Because they did not do this they did not actually research “acupuncture”. The description of this research in the published paper and in the press should have been as I discussed in the opening of this post. Instead genuinely interesting research that may lead to novel pain treatments is being diverted as propaganda for an ancient superstition.
