Acupuncture, an integral treatment modality of traditional Chinese medicine, has been used for at least 2500 years to treat disease. The therapy is based on stimulation of acupuncture points beginning with sharpened stones in very ancient times and advancing through the millennia to include a variety of techniques (e.g. needles, heat, pressure, aquapuncture, electricity, laser).1 Clinicians trained in this modality, and who use it daily, know it works exceedingly well. Its clinical effectiveness has spurred extensive and successful research to prove its medical efficacy from a “Western” perspective; but what about the acupuncture point itself. Experimental investigation to define its features has proven more elusive. In this issue of AJTCVM, a research article describes both an investigation into the bioelectrical properties at acupoints and the bioengineering of a system capable of capturing those signals.
