Pulsed electro magnetic therapy is a form of biophysical therapy that produces a healing frequency that penetrates every cell in the body. The pet lies comfortably inside what looks like a short pipe with a 3-foot diameter while an attached generator produces the magnetic pulsation. There is absolutely no sensation while the pet's body is being totally penetrated by a vibrating electro magnetic field. This is a form of physical therapy, which has been used on humans and horses for at least a decade and is now available for companion animals. The pulsed frequency helps to reestablish the resting potential of the cell. The resting potential is proportional to the ion exchange occurring at the cell membrane and is responsible for the oxygen utilization of the cell. Pulsating magnetic fields can dramatically influence the ion exchange at the cellular level and thereby greatly improve the oxygen utilization of diseased or damaged tissue. The deterioration of oxygen utilization is known to be a problem in many medical branches, especially delayed healing and arthritis. Pulsed magnetic field therapy can reduce pain almost immediately by increasing oxygen to the damaged tissue and by increasing circulation and perfusion of the injured area.
