The effect of low-level laser therapy and physical exercise on pain, stiffness, function, and spatiotemporal gait variables in subjects with bilateral knee osteoarthritis: a blind randomized clinical trial

Arthritis, Near Infrared (NIR)/Red Light Therapy

This study sought to evaluate the effects of individual and combination therapies (low-level laser therapy and physical exercises) on pain, stiffness, function, and spatiotemporal gait variables in subjects with bilateral knee osteoarthritis. It concluded that a combination of exercise and laser therapy provided the best results for the other gait variables (cadence and duration of…

Laser Therapy Inhibits Tumor Growth in Mice by Promoting Immune Surveillance and Vessel Normalization

Cancer, Near Infrared (NIR)/Red Light Therapy

Laser therapy, recently renamed as photobiomodulation, stands as a promising supportive treatment for oral mucositis induced by oncological therapies. However, its mechanisms of action and, more importantly, its safety in cancer patients, are still unclear. Here we explored the anti-cancer effect of 3 laser protocols, set at the most commonly used wavelengths, in B16F10 melanoma…

Improving executive function using transcranial infrared laser stimulation

Cognitive Enhancement, Near Infrared (NIR)/Red Light Therapy

Transcranial infrared laser stimulation is a new non-invasive form of low-level light therapy that may have a wide range of neuropsychological applications. It entails using low-power and high-energy-density infrared light from lasers to increase metabolic energy. Preclinical work showed that this intervention can increase cortical metabolic energy, thereby improving frontal cortex-based memory function in rats.…

SPECT Perfusion Imaging Demonstrates Improvement of Traumatic Brain Injury With Transcranial Near-infrared Laser Phototherapy

Brain Injury/TBI, Near Infrared (NIR)/Red Light Therapy

Traumatic brain injury (TBI) is a growing health concern affecting civilians and military personnel. Near-infrared (NIR) light has shown benefits in animal models and human trials for stroke and in animal models for TBI. Diodes emitting low-level NIR often have lacked therapeutic efficacy, perhaps failing to deliver sufficient radiant energy to the necessary depth. In…

Safety and Efficacy of 630-nm Red Light on Cognitive Function in Older Adults With Mild to Moderate Alzheimer’s Disease: Protocol for a Randomized Controlled Study

Anti-Aging, Near Infrared (NIR)/Red Light Therapy

Studies have shown that excess formaldehyde accumulation in the brain accelerates cognitive decline in people with Alzheimer’s disease (AD). Recently, reports from our research team revealed that red light treatment (RLT) improved memory in AD mice by activating formaldehyde dehydrogenase (FDH) and thus reducing formaldehyde levels. Here, we developed a medical RLT device to investigate…

Psychological benefits 2 and 4 weeks after a single treatment with near infrared light to the forehead: a pilot study of 10 patients with major depression and anxiety

Depression and PTSD, Near Infrared (NIR)/Red Light Therapy

Many studies have reported beneficial effects from the application of near-infrared (NIR) light photobiomodulation (PBM) to the body, and one group has reported beneficial effects applying it to the brain in stroke patients. We have reported that the measurement of a patient’s left and right hemispheric emotional valence (HEV) may clarify data and guide lateralized…

The potential of transcranial photobiomodulation therapy for treatment of major depressive disorder

Depression and PTSD, Near Infrared (NIR)/Red Light Therapy

Major depressive disorder is a common debilitating mood disorder that affects quality of life. Prefrontal cortex abnormalities, an imbalance in neurotransmitters, neuroinflammation, and mitochondrial dysfunction are the major factors in the etiology of major depressive disorder. Despite the efficacy of pharmacotherapy in the treatment of major depressive disorder, 30%-40% of patients do not respond to…

Effects of Transcranial Photobiomodulation with Near-Infrared Light on Sexual Dysfunction

Erectile and Sexual Dysfunction, Near Infrared (NIR)/Red Light Therapy

Transcranial photobiomodulation (t-PBM) consists of the delivery of near-infrared (NIR) or red light to the scalp designed to penetrate to subjacent cortical areas of the brain. NIR t-PBM has recently emerged as a potential therapy for brain disorders. This study assessed the efficacy of repeated sessions of NIR t-PBM on sexual dysfunction. We performed a…

Photobiomodulation therapy for male infertility

Erectile and Sexual Dysfunction, Near Infrared (NIR)/Red Light Therapy

Male infertility is a worldwide critical condition that affects about the 7.5% of males in Europe leading to an increment of the couples referring to reproductive medicine units to achieve pregnancy. Moreover, in the recent years, an increased number of patients have required to freeze their gametes in order to preserve their fertility. Photobiomodulation (PBM)…
