Thus, some studies attempted to assess the adequacy of acupuncture regimen in clinical trials. In this study, the concept of acupuncture regimen adequacy in clinical trials is clarified and the research status and limitations are summarized. Moreover, the suggestions in the future researches are proposed in association with clinical practice characteristics of acupuncture, i.e. classifying assessment according to different types of acupuncture; conducting the assessment according to the treatment characteristics of different types of acupuncture; assessing the maturity of acupuncture regimens; evaluating the rationality of the control group according to the purpose of the study; and focusing on domains evaluation.
