I'm sorry I don't have a comment on your exact question, but I bet you will be very interested in this related presentation by Dr. J Tennant.
He has an electronic device that allegedly does something very similar to what happens in an acupuncture session and some additional things.
The device adds voltage to the body at the various acupuncture points. It can also report the voltage on the meridian at the various acupuncture points.
He has a very fascinating theory on the implications of this, including the effect of bad dental conditions on various health problems.
