Origin, development and advantageous disease spectrum of the "Zhibian (BL 54) through Shuidao (ST 28)" needling technique.

This paper systematically reviews the historical evolution of the "Zhibian (BL 54) through Shuidao (ST 28)" needling technique by examining the history of the needle, controversies and positioning of the Zhibian (BL 54), and the formation and essentials of the needling technique. Furthermore, the advantageous disease spectrum of this needling technique is summarized, and speculates on potential advantageous disease spectrum from the neural mechanisms of obtaining and achieving efficacy. Lastly, this paper discusses the inadequacies in the research on " Zhibian (BL 54) through Shuidao (ST 28)" needling technique, aiming to provide a comprehensive understanding and reference for further research on this technique.
