Pulsed Electromagnetic Field Therapy is a viable alternative to drugs for the treatment of pain in dogs due to a variety of causes such as arthritis, surgery, inflammation, and wounds. Pulsed Electromagnetic Field Therapy or PEMF affects pain perception in many different ways. It affects calcium ion movement, endorphin levels, acupuncture point stimulation, nerve regeneration, circulation, tissue oxygen, and even cellular metabolism. All these affects help reduce inflammation and promote healing.
How does it work? No one really has a definitive answer but there are some good theories and some good scientifically based research pointing to some very likely causes of the success of this treatment. One of the more prominent and most likely reasons for the reduction of pain and inflammation has to do with the calcium ion movement that an electrical field causes in the body. PEMF therapy causes a natural anti-inflammatory process to occur more rapidly. It binds Calcium and in a cascade of events produces Nitric Oxide (NO), a natural anti-inflammatory. NO then continues the natural healing process by reducing pain, improving blood flow, reducing swelling and helps in the production of a molecule called cGMP, a growth factor producer. This growth factor producer helps in the regeneration of blood vessels and tissue growth and remodeling.
