Abstract: ABSTRACTBackground: unspecific effects of a technique may occur for several different reasons and play an important role when defining its efficacy. There is no information on any study in the Western world that has created or validated a scale that evaluates the possibility of the control technique exerting physiological effects and, therefore, underestimating the effect of acupuncture. Methods: a literature review was performed, and the most important items concerning the control technique that might exert a physiological effect were listed and scored according to their importance, based on the Jadad scale. Three experienced acupuncturists evaluated the index, suggested modifications or enhancements, and tested it. Results: score ranges from 0 to 10, from items 1 to 4, adding up to a total; next, such total is multiplied according to the importance attributed to it, on item 5, ranging the corrected total from 0 to 20. Despite the index's objectiveness, the specialists made some mistakes when using it, making the Friedman test non-significant. Discussion: the index was developed so that, the higher the score, the higher the probability of the control technique exerting a physiological effect. Despite the difference of scores among evaluators, these mistakes are rarely attributable to inter-rater subjectivity or uncertainties to items, as all of them are quite objective. Only one item in 145 scored showed diverging opinions. Conclusion: we have created an index of control adequacy (placebo or sham) for acupuncture studies that may be used with great objectivity by specialists and non-specialists.
