Laser Therapy for Pain

Angiogenesis and
Re-establishing Nerve Supply

(see pictures below)

With any healing device we always look to see what the main function of healing is. We know that there are multiple functions occurring at the same time when the Class IV laser is used but
what are the most important. 
The top two
, if stimulated will stimulate the healing.  Dr McGinnis’s opinion is the blood flow (Angiogenesis)  and the returning nerve supply  ( re- synapse).
Angiogenesis is the physiological process through which new blood vessels form from preexisting vessels. Angiogenesis is a normal and vital process in growth and development, as well as in wound healing.

This is why he feels the laser is so successful and rapid in aiding the healing process in different types of injuries and wounds. He states” if you can get the blood supply and the nerve supply back to the rapidly after a injury it will heal faster” that’s  just  what the Class IV laser does. It takes what the body is already capable of doing and speeds up the process in the area he uses the lasers on.

Here are examples of what the returning nerve synapse and the creation of new capillaries from existing one as explained above.

  The Physiological Effects of Laser Therapy

• Biostimulation including Improved metabolism & Increase of cell metabolism
• Improved blood circulation and vasodilatation
• Analgesic effect
• Anti-inflammatory and anti- edematous effects
• Stimulation of wound healing

  Benefits of Laser therapy to Users

• Relieves acute and chronic pains
• Increases the speed, quality and tensile strength of tissue repair
• Increases blood supply
• Stimulates the immune system
• Stimulates nerve function
• Develops collagen and muscle tissue
• Helps generate new and healthy cells and tissue
• Promotes faster wound healing and clot formation
• Reduces inflammation

These new therapeutic lasers have made tremendous contributions to human health care and has been credited with many important beneficial effects in human treatment:

• Analgesia of significant duration
• Accelerated healing of soft-tissue injuries and wounds

• Increased circulation—both vasodilation and vascularization

• Anti-inflammatory and anti-microbial action

• Reduced scarring

• Increases in collagen fibers and bone nodule formation

• Greatly increased patient comfort and ROM

Laser or Photobiomodulation in the target tissues  will produce the following actions

Increase Nerve Conduction
Increase Capillary Dilation

Releases Nitric Oxide
Increase ATP Production
Increase Fibroblast Migration
Increase Macrophage activity
Increase Keratinocyte activity
Increase RNA DNA Synthesis
Increase Enzyme production
Increase SOD Production

Increase Electromotive action acting on membrane bound ion channels
Increase Intracellular & extracellular ion gradient changes

Acupuncture meridian point stimulation

Clinical Effects
Reduced spasm
Pain relief
Increased circulation
Improved healing
Improved flexibility
Improved function
Reduced symptoms associated with osteoarthritis

  Biological Effects of the K laser

Class IV laser therapy Clinical studies and trials of laser therapy technology indicate the following beneficial effects of laser light therapy on tissues and cells:

Accelerated Tissue Repair And Cell Growth
Photons of light from lasers penetrate deeply into tissue and accelerate cellular reproduction and growth. The laser light increases the energy available to the cell so that the cell can take on nutrients faster and get rid of waste products. As a result of exposure to laser light, the cells of tendons, ligaments and muscles are repaired faster.

Faster Wound Healing
Laser light stimulates fibroblast development [fibroblasts are the building blocks of collagen, which is predominant in wound healing] in damaged tissue. Collagen is the essential protein required to replace old tissue or to repair tissue injuries. As a result, LT is effective on open wounds and burns.
Reduced Fibrous Tissue Formation
LT reduces the formation of scar tissue following tissue damage from cuts, scratches, burns or surgery.

Laser light therapy has an anti-edemic effect as it causes vasodilation, but also because it activates the lymphatic drainage system [drains swollen areas]. As a result, there is a reduction in swelling caused by bruising or inflammation.

Anti-Pain [Analgesic]
Laser therapy has a high beneficial effect on nerve cells which block pain transmitted by these cells to the brain and which decreases nerve sensitivity. Also, due to less inflammation, there is less edema and less pain. Another pain blocking mechanism involves the production of high levels of pain killing chemicals such as endorphins and enkephlins from the brain and adrenal gland.
Improved Vascular Activity
Laser light will significantly increase the formation of new capillaries in damaged tissue that speeds up the healing process, closes wounds quickly and reduces scar tissue. Additional benefits include acceleration of angiogenesis, which causes temporary vasodilatation, an increase in the diameter of blood vessels.

Increased Metabolic Activity
 Laser therapy creates higher outputs of specific enzymes, greater oxygen and food particle loads for blood cells.
Improved Nerve Function
Slow recovery of nerve functions in damaged tissue can result in numbness and impaired limbs. Laser light will speed up the process of nerve cell reconnection and increase the amplitude of action potentials to optimize muscle action.

Laser light has a direct effect on immunity status by stimulation of immunoglobines and lymphocytes. LT is absorbed by chromophones [molecule enzymes] that react to laser light. The enzyme flavomono-nucleotide is activated and starts the production of ATP [adenosine-tri-phosphate], which is the major carrier of cell energy and the energy source for all chemical reactions in the cells.

Trigger Points and Acupuncture Points
 Laser therapy stimulates muscle trigger points and acupuncture points on a non-invasive basis providing musculoskeletal pain relief

    Clinical Results

  • Laser therapy treatment helps reduce pain and inflammation and enhances tissue healing—both in hard and soft tissues, including muscles, ligaments, and even bones


  • It increases oxygenation of tissues and allows injured or damaged cells to absorb photons of light, which speeds healing. Class 4 laser therapy can be effectively combined with a number of other treatment modalities


  • Laser therapy can be helpful for acute injuries, such as strains, sprains, and shoulder injuries; repetitive-use injuries, such as carpal tunnel syndrome; traumatic injuries, and chronic issues, such as frozen shoulder and arthritis

  • Laser therapy is also used by some veterinarians to treat arthritic conditions, hip dysplasia, or intervertebral disc disease
