OBJECTIVE: To establish a standardized framework encompassing the precise locations, manipulations,functions and indications of specific acupoints in the field of paediatric Tuina. METHODS: The development of consensus involved three distinct stages. Initially, a list of paediatric Tuina specific acupoints was compiled based on an extensive literature review, which was subsequently supplemented through expert interviews. In the second stage, the Delphi method was employed to assess the significance of acupoint locations, manipulations, functions, and indications. In situations where the questionnaire survey failed to yield agreement or when the experts held reservations, the nominal group approach was utilized during the expert consensus meeting. The final version of the technical standardized material was ultimately determined during an expert consensus conference. After undergoing external peer review and evaluation, the completed draft was prepared for public dissemination RESULTS: The comprehensive list identified a total of 66 specific acupoints. The location and manipulation questionnaire consisted of 156 items based on the literature database, while the function and indication questionnaire contained 116 items. Two rounds of Delphi surveys were conducted for the location and manipulation category, and another two rounds of Delphi surveys were conducted for the function and indication category. During the experts consensus meeting The panel of experts conducted in-depth discussions on 61 questions, resulting in the formulation of technical guidelines for the locations, manipulations, functions, and indications of 64 paediatric Tuina acupoints. Subsequently, the research team compiled and edited the draft of the technical guidelines for acupoints of paediatric Tuina, which was finalized after external review and feedback. CONCLUSION: This study successfully established the recognized technical standards for practitioners of paediatric Tuina, thereby standardizi
