Validation of a new placebo acupuncture method with potential for double blinding: Phase II: practitioner blinding. (2018). Odontoestomatología, 20(32). https://odon.edu.uy/ojs/index.php/ode/article/view/235
Abstract
Se presenta un nuevo método de acupuntura placebo, evaluándose en esta fase el cegamiento del operador. Metodología: Se implementaron dos estudios experimentales utilizando como referencia el punto acupuntural Intestino Grueso 4 (IG4). En el primero (I) tres operadores utilizaron el dispositivo desarrollado en un mismo paciente. Mientras que en un segundo experimento (II), un único acupunturista utilizó dicho dispositivo en 12 voluntarios sanos. Resultados: En I, sobre un total de 30 agujas que utilizaron los operadores, estos pudieron identificar correctamente 7 (23%). Por otra parte, en el experimento II, los porcentajes de acierto encontrados no fueron significativamente diferentes de 50%, por lo cual no hay evidencia suficiente que permita decir que el acupunturista reconoce el tipo de aguja que está utilizando. Conclusiones: El nuevo dispositivo evidenció un alto potencial de cegamiento del operador, sugiriendo que es útil para enmascarar incluso a acupunturistas experimentados.
