[Formation mechanism and clinical application of "using emptiness as acupoints" based on the <i>Jingjin</i> theory].

Throughout history, physicians have emphasized "using pain as acupoints" as an important reference and principle for acupuncture point selection. However, the formation mechanism and significance of clinical application of the feeling of emptiness during acupoint palpation have been less explored. This paper summarizes this phenomenon as "using emptiness as acupoints," and analyzes and discusses its meaning, formation mechanism, and clinical application. It proposes a systematic and comprehensive theoretical system for <i>Jingjin</i> diagnosis and treatment, combining "using emptiness as acupoints " with "using pain as acupoints", "using comfort as acupoints" and "using knots as acupoints", as well as "knotted <i>Jingjin</i> lesion points" and "scattered <i>Jingjin</i> lesion points," and integrating the patient's subjective sensations with the physician's palpation feelings. This approach aimes to provide new insights for the clinical treatment of <i>Jingjin</i> diseases.
