What`s cold laser therapy?
Cold laser therapy is a low-intensity laser therapy that stimulates healing while using low levels of light.
This technique is known as “cold” laser treatment because low levels of light are not sufficient to heat the body’s tissues. Light levels are lower compared to other forms of laser therapy, such as those used to destroy tumors and coagulate tissues.
Main clinical Function
1, Strong analgesia: reduce peripheral nerve excitability; promote the release of tissue enkephalin analgesic substances; reduce serotonin content
2, rapid anti-inflammatory effect: laser can adjust the body’s immune system to achieve anti-inflammatory effect; can improve blood circulation, reduce local congestion and edema.
3, promote tissue repair: increase capillary density, promote local blood circulation, stimulate protein synthesis, regenerate new epithelial tissue, repair damaged soft tissue, and promote bone tissue regeneration.
4, biological regulation: enhance the body’s immune function, regulate endocrine, so that blood cells are regulated in both directions.
Biostimulation of weak lasers:
(1) Weak laser light A laser that does not directly cause irreversible damage to biological tissues is called a weak laser.
(2) weak laser stimulation
Weak laser irradiation can affect the body’s immune function, stimulate the nerve tissue and function, and can also cause a series of other biological effects in the living organism.
Laser biostimulation has the following characteristics:
(a) Stimulation or inhibition: a small dose of laser light stimulates, while a large dose suppresses; the division of large and small doses varies with the structure and function of the organism.
(b) Accumulation: A small dose of laser has an accumulating effect, that is, a large dose of radiation or a dose of multiple doses of multiple doses, the biological effect is as large.
(c) Parabolic effect: the number of times of irradiation has a threshold value, and the effect does not increase proportionally with the number of times. There is a maximum value. After reaching the maximum value, the number of times of irradiation is increased, and the stimulation effect is weakened or even suppressed.
