1. Accelerated Tissue Repair and Cell Growth
Photons of light from lasers penetrate into tissue and accelerate cellular growth and reproduction. Laser therapy increases the energy available to the cell so it can work faster, better, and quickly get rid of waste products. When cells of tendons, ligaments, and muscles are exposed to laser light they repair and heal faster.
2. Faster Wound Healing
Laser light increases collagen production by stimulating fibroblasts. Collagen is the building block of tissue repair and healing. Laser therapy increases fibroblast activity and therefore collagen production to speed healing.
3. Reduced Fibrous Tissue Formation
Low level laser therapy decreases scar tissue formation. Scar tissue can be a source of chronic pain and poor healing. By eliminating excessive scar tissue and encouraging proper collage production, painful scars and chronic pain is reduced.
Laser therapy causes vasodilatation, or increases blood flow. It also increases lymphatic drainage to decrease swelling or edema from accumulating. Therefore, laser therapy reduces swelling caused by bruising or inflammation while speeding the recovery process.
5. Pain Relief
K Laser therapy decreases pain by blocking pain signals to the brain. Some nerve cells sense pain and send signals to the brain. This protective mechanism can be overly stimulating producing chronic pain and nerve sensitivity. Also by decreasing the inflammation and edema, it further decreases the pain sensation. Laser therapy also increases endorphins and enkephalins, which block pain signals and decrease pain sensation. The laser therapy decreases the painful nerve signals and increases mechanisms to decrease pain.
6. Increased Blood Flow
In the body increased blood flow usually means increased healing. Blood carries nutrients and building blocks to the tissue, and carries waste products away. Laser therapy increases the formation of small blood vessels or capillaries in damaged tissue. Increased blood vessels and blood flow improves the body’s ability to heal and repair.
7. Increased Repair and Regeneration
Laser therapy increases enzyme activity to improve metabolic activity that affects cell repair and regeneration. The enzymes are turned on “high” to speed the healing.
8. Nerve Function and Repair
Nerves can heal very slowly or have difficulty to completely heal. Lasers speed up this process. Damage to specific nerves produces numbness, impaired function, or increased pain. Laser therapy treatments speed the amplitude of action potentials to restore nerve function and reduce pain.
9. Increased Energy Production – ATP
Certain enzymes (chromophores) can be activated to increase cellular production of ATP. ATP is like gasoline for cells, it is the energy source that cells operate. Injured cells often have low levels of ATP, which decreases their ability to heal and repair. By increasing ATP and “gasoline storage levels,” cells have more ATP to work and repair. This process is particularly important with nerve pain.
10. Acupressure and Trigger Points
Low level laser therapy decreases trigger points and stimulates acupuncture points to decrease muscle and joint pain.
