ABSTRACT:
Regeneration of damaged tissue, whether in the skin, tendons or elsewhere in the body begins with the growth and proliferation of cells which take place along a migratory path and in a polar direction that depends on the nature of the injury. Thus in some situations, regenerative cells and non-cellular healing components migrate radially from the outskirts of the damaged tissue region toward the center thereof, while in others migration is along a longitudinal or transverse path. To stimulate and enhance this regenerative process and thereby promote rapid healing of the damaged tissue, use is made of an exogenous electrical stimulation technique in which cathode and anode electrodes are placed in or near the region. Impressed across the electrodes is a DC potential whose magnitude is sufficient to cause a minute ionic and electronic current to flow between the electrodes through the region. The electrodes are so shaped and oriented relative to the region that the resultant current flow is substantially along the same path followed by the migrating cells in the course of the regenerative process and in a polar direction conducive to healing.
