Yes, I only read a study about it. And it said:
Low-level laser(light) therapy also known as photobiomodulation (PBMT), Low-intensity light therapy, and cold laser therapy.
It’s used for many purposes like the relief of pain and inflammation, and restoration of function. It’s fast-growing technology. Low-level laser therapy is used for coherent and noncoherent light sources consisting of light-emitting diodes.
The main purpose of LLLT is to reduce inflammation and pain.
For observation, it is observed that LLLT has a wide range of effects at the molecular, cellular, and tissue level.
Although LLLT is now used to treat a wide variety of ailments.
Low-level laser(light) therapy has been found to be effective in numerous medical conditions. It has been observed that this therapeutic solution could relieve short-term pain in acute and chronic solutions.
It was basically just a basic introduction.
