In this article, the author shows that "stimulation of the soft tissue in special areas on the body produces an electric current. This piezoelectrically induced current activates the healing processes in the stimulated area, and it is able to flow “towards the internal organs along the semiconductive channels of biological micromolecules”.
You can produce the electric current in these tissues, and it has enormous healing potential on the cellular, tissue and organ levels. This electric current is able to travel to the distant parts of the body, including the inner organs and normalize their function."
Below are excerpts from this well written exploration in manual therapy and piezoelectricity:
