Clinical studies and trials of FDA Cleared laser therapy indicate the following beneficial effects of laser light therapy on tissues and cells:
- Accelerated Tissue Repair And Cell Growth.
Photons of light from lasers absorbs deeply into tissue and accelerate cellular reproduction and growth. No other physical therapy modality can absorbs as deep without invasive procedures. The laser light increases the energy available to cells so that cells can take on nutrients faster and get rid of waste products. Cells of cartilage, bone, tendons, ligaments and muscles are repaired faster as a result of exposure to laser light.
- Reduced Fibrous Tissue Formation.
Laser therapy reduces the formation of scar tissue following tissue damage and acute and chronic inflammatory processes. This point is paramount because fibrous (scar) tissue is less elastic, has poorer circulation, is more pain sensitive, is weaker, and is much more prone to re-injury and frequent exacerbation.
Laser light therapy has an anti-inflammatory effect, as it causes vasodilation and activation of the lymphatic drainage system. As a result, there is a reduction in swelling caused by biomechanical stress, trauma, overuse, or systemic conditions.
Laser therapy has a beneficial effect on pain through the suppression of nerve signal transmission over unmyelinated c-fibers that transmit pain to the brain. This means that a greater amount of stimuli is required to create an action potential within the nerve to signal pain. Another pain blocking mechanism involves the production of high levels of pain killing chemicals such as endorphins and enkephalins from the brain and adrenal gland.
- Improved Vascular Activity.
Laser light will significantly increase the formation of new capillaries (angiogenesis) in damaged tissue that will speed up the healing process. Additionally, the literature has noted that microcirculation increases secondary to vasodilation during laser treatment.
- 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 function in damaged tissue can result in motor and sensory disturbances resulting in loss of function to the affected extremity. Laser therapy accelerates the process of nerve cell regeneration and increases the amplitude of action potentials to optimize motor and sensory nerve functions.
- Trigger Points and Acupuncture Points.
Laser therapy stimulates muscle trigger points and acupuncture points on a non¬invasive basis providing musculoskeletal pain relief. Additionally, a restoration of muscular tonus and balance between agonist, antagonist, and synergistic relationships improves joint biomechanics and protects them from potentially dangerous stress/strain and shear forces.
