| Research Abstract |
Physiological activities of various sham devices used in clinical trials of acupuncture were examined by recording the neural activities of sensory afferents in humans and central neurons in rats. Almost every sham interventions (shallow needling, non-penetrating needle with blunt tip, mechanical stimulation of the skin), could activate the polymodal receptors which assumed as common candidate for acupuncture and moxibustion stimuli. Press tack needle could activate the nociceptive specific neurons participated in endogenous pain inhibitory system and rewarding system (pleasantness), but its sham had no effect. These results suggest that lack of statistical difference between real acupuncture and so-called sham acupuncture treatments in recent clinical trials could be explained as two types of acupuncture treatments produce similar therapeutic effects.
