Lasers are given a class number based on how powerful they are, with the numbers running from 1 thru 4. Any laser with a potential to deliver an average power greater than half of a Watt (or 500 milliWatts) is a Class 4 laser. Examples include the Vaymed Series, as well as surgical and industrial lasers. Vaymed Series is at the very low end of the Class 4 laser range, and the beam is allowed to spread out, so the effect is therapeutic, not cutting or damaging.

As one of the most important inventions of the 20th century, laser has very unique advantages. Laser is generated based on the principle of stimulated radiation. Compared with ordinary light sources, laser has three major characteristics: 1. Monochromaticity. The light emitted by laser is monochromatic light with extremely high purity. Therefore, laser can highly concentrate light energy to a wavelength with specific clinical effects, and the laser light treatment efficiency is much higher than that of ordinary light sources. 2. Unidirectionality. Laser can propagate a long distance but the diffusion angle is extremely small. Therefore, for the irradiation of target tissue, laser can well ensure the convergence of light energy in space. 3. Coherence. The photons emitted by the laser have the same phase (the photons are in step), so when the laser interacts with biological tissue, it can obtain very good absorption efficiency and promote the target tissue to produce photobiomodulation.

Laser physiotherapy is not limited to pain management; its clinical applications are extensive, covering various therapeutic areas. These include promoting tissue repair and regeneration, modulating inflammation, and enhancing local blood circulation. In clinical practice, approximately 80% of cases can be combined with laser physiotherapy as an auxiliary treatment to enhance the body's repair function in sick animals. Laser therapy is often overlooked in the treatment of internal medicine diseases. However, research and clinical practice have demonstrated its clear application value in internal medicine, particularly in inflammatory, chronic, or convalescent conditions, where its effects are remarkable.

Yes. Laser therapy is generally regarded as a nice adjunct to regenerative medicine. Not only will it help the transplanted cells survive, proliferate, and function but it will enhance/improve the general health of the tissue and structures being treated for optimal recovery. Always be very conservative when treating a recently (5-7 days) injected joint.
