This article presents a novel model of acupuncture physiology based on cellular calcium activation by an acoustic shear wave(ASW) generated by the mechanical movement of the needle. An acupuncture needle was driven by a piezoelectric transducer at100 Hz or below, and the ASW in human calf was imaged by magnetic resonance elastography. At the cell level, the ASW activatedintracellular Ca2+ transients and oscillations in fibroblasts and endothelial, ventricular myocytes and neuronal PC-12 cells along with frequencyamplitudetuning and memory capabilities. Monitoring in vivo mammalian experiments with ASW, enhancement of endorphin in blood plasmaand blocking by Gd3+ were observed; and increased Ca2+ fluorescence in mouse hind leg muscle was imaged by two-photon microscopy. In contrast with traditional acupuncture models,the signal source is derived from the total acoustic energy. ASW signaling makes use of the anisotropy of elasticity of tissuesas its waveguides for transmission and that cell activation is not based on the nervous system.
