The science behind photo-therapy

How photo-therapy works – The short version

Every cell in an animal’s body contains mitochondria which are like the battery of the cell. The mitochondria produce a chemical called ATP which provides the chemical energy to drive the chemical reactions in the cell, enabling it to function normally.

When an animal is injured or the body is fighting a disease the mitochondria in the  affected cells are compromised – the ‘battery’ becomes discharged and no energy is produced for normal function. The cell is no longer able to absorb nutrients or oxygen.

When Photizo is applied the ‘battery’ of the compromised cell immediately recharges, removing the surrounding inflammation and ensuring that adequate oxygen and nutrient supplies are restored, allowing the cell to function normally again.

The correct dose of light can improve the rate and quality of acute and chronic wound healing, pain relief, inflammation, immune system functioning and nerve regeneration, however effectiveness wholly depends on the type of light (wavelength) used, intensity, and total energy (Joules/cm2) delivered. Too much or too little energy delivered to injured site can be ineffective.

How photo-therapy works – The science bit

Photizo® Vetcare stimulates the energy production (ATP) inside the cell, by up to 250 times, thereby stimulating the cells to function at optimum levels. It further stimulates and regulates the DNA and RNA synthesis (the programmes inside the cell) to follow the correct healing process, and regulates scar tissue/proud flesh formation. This speeds up the natural healing process by up to 40%, and reduces the likelihood of excess scar tissue formation and complications.

Photizo® Vetcare stimulates endorphin and serotonin secretion. These are the body’s own pain and relaxing ‘medication’. Photizo® Vetcare effectively reduces the inflammatory process that is caused by damage, injury or overuse and reduces muscle spasms and trigger points.

It assists in reducing swelling by increasing the blood vessel and lymph diameter to clear excess waste products from the injured or inflamed area. This reduces the pressure and irritation on nerve endings that causes more pain, and increases blood flow into the area, ensuring that the tissues can absorb more nutrients and oxygen.

This also helps to reduce excess wound substrate to reduce the risk of secondary bacterial infections. The increased blood supply to the area ensures higher concentrations of topical and systemic medications delivered to the affected area.

Photizo® Vetcare stimulates the immune cells, to react against infections and also stimulates optimum cell condition (skin, bone, nerve, capsule, cartilage and muscle tissue) to maintain healthy tissue. This may help to prevent degeneration of tissues like nerves, bone/joints and blood vessels.

An evolving science…

Many new applications for this treatment are being used and investigated for humans including smoking cessation, weight loss, addiction therapy, nerve regeneration for spinal cord injuries, and muscle atrophy for astronauts on long term space missions. The term adopted by NASA and U.S. military scientists is Photobiomodulation.

Photobiomodulation Therapy (using both LED and laser) and has been the subject of several reviews for a range of musculoskeletal issues with favourable conclusions reported by The Lancet,  the British Medical Journal, the International Association for the Study of Pain and the World Health Organisation.
