Why the study?
Does AC impedance differ between acupuncture points Li-4 and Li-12 compared to anatomically similar control points?
Does AC impedance differ between acupuncture points Li-4 and Li-12 compared to anatomically similar control points?
Acupuncture points Li-4 and Li-12 exhibit lower series resistance and characteristic impedance, and higher signal propagation velocity, compared to anatomically similar control points.
Supports distinct electrical properties at acupuncture points; leaves open clinical relevance and requires validation.
AC impedance between two acupuncture points (Li-4 and Li-12) and two pairs of anatomically similar points with the same separation was studied via Laplace plane analysis of the time domain current response to a predetermined voltage perturbation. The series resistance between the two acupuncture points was found to be significantly lower than between either pair of control points. The characteristic impedance of an equivalent transmission line was lower and the signal propagation velocity higher for the acupuncture point system as compared to both controls.
