In a nutshell - Practically everything you could wish it to do. Apart from effectively treating every injury imaginable, with an average acceleration of 50% of the normal healing time, the Porta-Mag can also be used to: Calm excitable dogs - Prepare and condition dogs for work or the show ring - Accelerate recuperation from heavy work and more.

The History of Magnetic Field Therapy

The application of magnets to speed healing of human bone and other injuries has been used for thousands of years. Scrolls dating from 2800BC report on the use of natural magnets or lodestones by the ancient Egyptians.

During the 20th Century, electromagnetic fields generated by passing a low power current through copper coils has become a popular form of applying magnetic therapy. Since the 1950's, pulsed magnetic fields have been acknowledged as an aid to healing bone, ligaments, tendons and soft tissues in human athletes as a physiotherapy mode. The use of magnetic therapy has become popular as a safe, simple, non-sensational, non-invasive form of physiotherapy. Pulsed magnetic fields have been recognised as the most useful form of magnetic therapy in both animals and humans.

The 'pulsed' electromagnetic field (PEMF) is produced as the current to the electromagnetic coils is turned on, and off, repeatedly. This ranges from one or two 'pulses' per second, up to 40 pulses per second. The pulsing is controlled electronically in the generator unit. The system is believed to work effectively due to its bmagnetic lines of force aligning electrolytes and minerals and other charged particles within the tissues.

How Pulsed Electromagnetic Fields (PEMF) Work

The principle of electromagnetic therapy is based on the physiology that living blood, bone and tissue cells have an electrical potential that is produced by the inflow and outflow of charged particles or ions between the blood, fluids and cells. These charged ions include oxygen, calcium, proteins and electrolytes that can be assisted to move more or less rapidly between the cells and fluids.

Studies have shown that the human body has an electromagnetic field of 1 micro Gauss (one millionth of a Gauss) and that the electronic or charged particle gradients of calcium and other ions across cell walls in 'membrane channels', are influenced by PEMF application, increasing the ion exchange activity to help re-establish and maintain normal cell function. It is the flow of calcium in and out of the blood and tissue cells that appears to exert the positive benefits of PEMF on bone healing by improving the rate of calcification and healing of fractures that are commonly slow to heal.

Blood lymphocyte cells were activated by PEMF to enhance their division and maturity at sites of injuries, which may have a beneficial effect on immune response.
