Photobiomodulation (also known as low-level light therapy) is a therapeutic method that uses low-level light energy to resolve pain and promote tissue repair and regeneration. This therapy is non-invasive and involves the application of red and near-infrared light to the skin. The light penetrates into the underlying tissues, where it can interact with cells to reduce inflammation and oxidative stress, enhance cell metabolism and proliferation, and activate pain-relieving mechanisms in the nervous system. Photobiomodulation has been shown to be effective for treating a wide range of pain conditions, including chronic pain, joint pain, musculoskeletal pain, and neuropathic pain.
Research has shown that photobiomodulation can be an effective tool in resolving pain and promoting tissue repair. A number of studies have investigated its use for treating various types of pain, including chronic pain, joint pain, and neuropathic pain.
One study published in the Journal of Pain Research found that photobiomodulation therapy was effective in reducing chronic low back pain, with patients reporting significant improvements in pain intensity, physical function, and quality of life after treatment.
Another study published in the journal Photomedicine and Laser Surgery found that photobiomodulation therapy was effective in reducing pain and improving function in patients with knee osteoarthritis. The study found that photobiomodulation therapy was as effective as non-steroidal anti-inflammatory drugs (NSAIDs) in reducing pain, and had the added benefit of not causing any adverse side effects.
Additionally, a number of animal studies have shown that photobiomodulation therapy can promote tissue repair and regeneration, and may be useful in treating a range of conditions, including wound healing, spinal cord injury, and nerve damage.
Overall, while more research is needed to fully understand the mechanisms by which photobiomodulation therapy works, the available evidence suggests that it may be a safe and effective tool for resolving pain and promoting tissue repair.
