Laser physiotherapy is praised as the light of life in 2 1 century by the medical community. It is a non-invasive treatment technology superior to other minimally invasive methods, and has the advantages of safety, non-invasive, painless, no side effects, short treatment time and high cure rate.
Then, what is the clinical function of animal laser physiotherapy and what are its indications?
The clinical function of laser physiotherapy can be summarized as three points: diminishing inflammation, relieving pain and promoting healing.
1. Promote active oxygen in vivo to regulate intracellular Ca++ concentration, thus regulating the stability of cell membrane.
2. Promote the production of cytochrome c oxidase, stimulate the production and synthesis of adenosine triphosphate (ATP), and contribute to cell repair, reproduction and functional ability.
3. Enhance the ability to accelerate the activity of white blood cells, so as to repair and regenerate the function of damaged parts of the body more quickly.
4. Increase the synthesis of PGI2 (prostacyclin), which has vasodilating and anti-inflammatory effects.
5. Mediate the role of lymphocyte helper T cells and suppressor T cells in inflammatory reaction.
6. Laser stimulates the increase of the level of cytokine superoxide dismutase (SOD) and interacts with other anti-inflammatory processes to accelerate the termination of the inflammatory process.
1. ion channel recovery. Ion channels are integral membrane proteins that allow ions to enter and leave cells, which is essential for normal cell function.
2. β -endorphin increased. These are endogenous analgesic hormones, which can reduce the pain level.
3. Increase the production of nitric oxide. This is one of the most important molecules for vascular health, and it is a vasodilator. It also plays a role in many biological processes within and between cells, and helps to relieve pain.
Reduce bradykinin levels. Lower levels of tissue irritants cause less pain.
4. Blocking the depolarization of C fiber afferent nerve is helpful to relieve neuropathic pain caused by nerve fiber injury.
5. Resting action potential recovery. This is very important for relieving pain.
Increase the release of acetylcholine (a neurotransmitter).
6. Axon germination and nerve cell regeneration. This helps to restore the function of body tissues.
1. Leukocyte activity increased. White blood cells are a part of human immune system, which can accelerate tissue repair and relieve pain.
2. Macrophage activity is enhanced. This is a kind of white blood cell, which first appeared in the infected area. Macrophages are the main mechanism used by the immune system to eliminate pathogens.
3. Add new blood vessels. This will lead to the growth of new blood vessels.
4. Increase the activity of fibroblasts. These are the most common connective tissue-producing cells, which can accelerate tissue repair.
5. Keratinocyte proliferation. These are epidermal cells, which reduce the healing time of skin and lead to early epithelial formation, covering wounds.
6. Increase the tensile strength. This helps to prevent re-injury.
Because the regulation function of laser physiotherapy is at the level of cells and tissues, its adaptation range is very wide, covering almost all parts of the body and most diseases.
