Clinical study of objective pulse diagnosis

The recording of the objective pulse diagnosis was performed and the meridian points were selected from this recording. The proper meridian points (five element points) according to the five element theory and the improper points (non-five element points) were stimulated. Pain threshold was elevated by the stimulation of five element points and not raised by non-five element points in a patient who had nasal polypectomy under acupuncture analgesia and also in 6 of 9 healthy volunteers. Naloxone reversal of elevated pain threshold was also observed in volunteers.
