Analysis of key therapeutic elements in acupuncture therapy and placebo acupuncture controls

Abstract

Identifying key acupuncture elements is essential for optimizing sham acupuncture controls. Based on the characteristics and current state of acupuncture therapy, this paper categorizes key acupuncture elements into types and contents. Taking the former as a clue, it examines the current understanding of key acupuncture elements and underscores the need for further refinement to ensure that sham acupuncture controls more closely approximate physiological inertness. Additionally, it explores strategies and methodologies for advancing the understanding of key acupuncture elements from both the type and content perspectives. Key acupuncture elements should expand the number of included element types. Elements such as acupuncture needles, point selection, point combination, needle insertion, needle manipulation, and needle withdrawal should all be included, and they should be reported in a standardized manner in the trials. Regarding element content, improvements should be made in three key areas to enhance selection accuracy: 1. Strengthening the comprehensiveness of relevant theoretical frameworks. 2. Emphasizing the role of Traditional Chinese Medicine (TCM) diagnosis and acupoint palpation methods in trial application and reporting. 3. Continuously investigating the mechanisms underlying both the specific efficacy and the placebo efficacy of acupuncture.
