Abstract
|
|
|
|
Sham acupuncture should have two distinct features: first, it must be morphologically similar to verum acupuncture for blinding purposes, and second, it must not exert physiologically expected effects of verum acupuncture. While several types of sham acupuncture are currently used, there are on-going debates on which sham acupuncture can meet the criteria for being an appropriate control intervention in acupuncture research. In view of this situation, it is unreasonable to regard the use of sham acupuncture in acupuncture research as the same as the use of placebo drugs in drug research. Given the current research evidence that sham acupuncture can exert not only the originally expected non-specific effects but also sham acupuncture-specific effects, it would be misleading to simply regard sham acupuncture as the same as placebo. Therefore, researchers should be cautious when using the term sham acupuncture in clinical investigations.
