Most of the objective data on acupuncture analgesia have been obtained with electroacupuncture rather than dry needling as described in the reference that Lewis cites; therefore we prefer electroacupuncture.

For instance, the electroencephalograph patterns (' brain waves') of people undergoing acupuncture analgesia are quite different from those of people put into states of analgesia through hypnotic suggestion.

We chose acupuncture points that had been used in most experiments with acupuncture analgesia, as well as in the two previous clinical studies, both of which were of electroacupuncture.

These findings may shed light on the CNS mechanism of acupuncture analgesia and form a basis for future investigations of endogenous pain modulation circuits in the human brain.

Studies on the enhanced effect of acupuncture analgesia and acupuncture anesthesia by D-phenylalanine (2nd report)- schedule of administration and clinical effects in low back pain and tooth extraction.

Many doctors and scientists now recognise that acupuncture can be of value for treating pain, and with this have come interesting new applications, bringing together traditional acupuncture and modern conventional medicine, as in electroacupuncture, and the combining of acupuncture analgesia with anaesthetics for major surgery.
