laser therapy beams light energy at your skin to reduce pain and inflammation deep within an area of your body, like your knee. It’s used to treat knee pain from osteoarthritis (OA), as well as low back pain, carpal tunnel syndrome, rheumatoid arthritis (RA), fibromyalgia, tendinitis, nerve pain, and sports injuries.
Cold laser therapy was first developed in the 1960s. It’s also called low-level laser therapy (LLLT), soft laser therapy, or photobiomodulation therapy (PBMT).
Once the light energy passes through the layers of skin and reaches the target area, it is absorbed and interacts with the light sensitive elements in the cell. This process can be compared to photosynthesis in plants - sunlight is absorbed by plants, which is then converted to usable energy so that the plant can grow.
When cells absorb this light energy, it initiates a series of events in the cell that is theorized to eventually result in normalizing damaged or injured tissue, a reduction in pain, inflammation, edema and an overall reduction in healing time by increasing intracellular metabolism.
