Abstract Rheumatoid arthritis (RA) and osteoarthritis (OA) have a significant impact on the quality of life of patients around the world, causing significant pain and disability. Furthermore, the drugs used to treat these conditions frequently have side effects that add to the patient’s burden. Photobiomodulation (PBM) has emerged as a promising treatment approach in recent […]
Non-Invasive Treatment of Early Diabetic Macular Edema by Multiwavelength Photobiomodulation with the Valeda Light Delivery System
Abstract Purpose Diabetes is associated with ocular complications including diabetic macular edema (DME). Current therapies are invasive and include repeated intravitreal injections and laser therapy. Photobiomodulation (PBM) is a treatment (Tx) that utilizes selected wavelengths of light to induce cellular benefits including reduction of inflammation and edema. This single-center, open-label, post-hoc analysis explored the utility […]
Mechanisms and applications of the anti-inflammatory effects of photobiomodulation
Abstract Photobiomodulation (PBM) also known as low-level level laser therapy is the use of red and near-infrared light to stimulate healing, relieve pain, and reduce inflammation. The primary chromophores have been identified as cytochrome c oxidase in mitochondria, and calcium ion channels (possibly mediated by light absorption by opsins). Secondary effects of photon absorption include […]
Biphasic Dose Response in Low Level Light Therapy
Abstract The use of low levels of visible or near-infrared light for reducing pain, inflammation, and edema, promoting healing of wounds, deeper tissues, and nerves, and preventing cell death and tissue damage has been known for over forty years since the invention of lasers. Despite many reports of positive findings from experiments conducted in vitro, […]
Biphasic dose response in the anti-inflammation experiment of PBM
Abstract Non-invasive laser irradiation can induce photobiomodulation (PBM) effects in cells and tissues, which can help reduce inflammation and pain in several clinical scenarios. The purpose of this study is to review the current literature to verify whether PBM can produce dose effects in anti-inflammatory experiments by summarizing the clinical and experimental effects of different […]
Anti-inflammatory effects of low-level laser therapy (LLLT) with two different red wavelengths (660 nm and 684 nm) in carrageenan-induced rat paw edema
Abstract It has been suggested that low-level laser therapy (LLLT) can modulate inflammatory processes. The aim of this experiment was to investigate what effects red laser irradiation with two different wavelengths (660 nm and 684 nm) on carrageenan-induced rat paw edema and histology. Thirty two male Wistar rats were randomly divided into four groups. One group received a sterile saline injection, […]
Photobiomodulation—Underlying Mechanism and Clinical Applications
The purpose of this study is to explore the possibilities for the application of laser therapy in medicine and dentistry by analyzing lasers’ underlying mechanism of action on different cells, with a special focus on stem cells and mechanisms of repair. The interest in the application of laser therapy in medicine and dentistry has remarkably […]
Visual red-light stimulation for improving sleep quality in older adults
Abstract Insomnia is one commonly reported sleep problem especially among older adults. Presently, it is treated by oral medicines. Since it has side effects, non-invasive therapies are one better alternative. Light in the band of 650 to 700 nm wavelength stimulate the production of melatonin. Hence red light is used in controlled mechanism to induce […]
