Scientists have known for sometime that acupuncture points have lower electrical resistance than other areas on the surface of the body. Dr. Morry Silberstein of the Curtain University of Technology, recently discovered that a type of nerve cell, called C fibres, branch at acupuncture points. C fibres transmit sensory information over long distances in the body, and that "insertion of the acupuncture needle disrupts this circuit and numbs our sensitivity to pain."
Acupuncture is being used in the Air Force for pain relief. Dr. Niemtzow, a consultant for the Surgeon General of the Air Force, says that acupuncture "is one of the fatest pain attenuators in existence." Dr. Niemtzow's technique, called Battlefield Acupuncture, is being taught to physicians deployed to Afghanistan and Iraq. It uses points on the ear which block pain signals to the brain to relieve pain for several days.
