Dermatology, ophthalmology, dentistry, otolaryngology, cardiology, and neurology are only a few of the fields that have benefitted, and in some cases lasers have revolutionized the way we treat patients 1416. However, until now lasers medical applications have been confined to their ability to selectively ablate tissue. Mechanism Perhaps the most obvious question with transcranial laser therapy (TLT) is regarding the mechanism of action. It is known how lasers can cut or cauterize, but how a laser applied to the scalp during an ischemic stroke can improve outcomes is more difficult to comprehend. Several postulated mechanisms seem unlikely. Heat production, although closely associated with lasers, did not appreciably elevate brain temperature in preclinical studies, suggesting that photothermal effects do not play. Curr Cardiol Rep (2010) 12:2933 role. Hemodynamic effects (ie, recanalization and augmented collateral blood flow) are similarly unlikely because the interval from symptom onset to treatment extends to.

Thus, there is a need for new therapies that can extend the treatment window. History Interactions between light and biology have been recognized since the concept of photosynthesis originated in the 17th century. Priestley, among others, elucidated the influence of sunlight on plants 11, and by the 1770s the basic reaction incorporating water and carbon dioxide uptake was outlined. Radiation remained poorly understood until the 1900s when Albert Einstein published his groundbreaking paper on photoelectric effects and concepts of absorption, spontaneous emission, and stimulated emission of electromagnetic radiation. Five decades later the term laser (light amplification by stimulated emission of radiation) was coined and shortly thereafter the first human-made laser was created in 1960. We now understand that photobiological reactions such as photosynthesis entail the absorption of a specific wavelength kaken of light by a specific molecule. These molecules, or photoreceptors, become electronically excited by absorbing light and subsequently participate in a metabolic reaction unrelated to the original light response. Thus, a laser is simply a tool that uses a light source to excite these molecules; however, the biological effects of any laser are wavelength specific when not simply used for tissue destruction. Since inception, laser technology has been applied to a broad spectrum of industries and professions, but some of the most meaningful applications have been in medicine. The process began in the 1960s but lasers have infiltrated many fields of medicine.

Introduction Stroke affects nearly three quarters of a million people each year in the United States, of which more than three quarters are ischemic. It is the leading cause of adult disability and the third most common cause of death in industrialized nations. Despite its prevalence, the only proven treatment for acute ischemic stroke is intravenous tissue plasminogen activator (tPA) 3, and although approved in 1995, frustratingly few patients receive therapy 4,. There are several reasons for this. Initially, neurologists and emergency medicine physicians were tentative to administer tPA because of the perceived risk of causing symptomatic intracranial hemorrhage (sICH). Data revealing an extremely low incidence of sich addressed many of these concerns 6, although skepticism still exists in the emergency medicine community. Nonetheless, the single largest factor currently limiting tpa use is that, per the ninds study protocol, it must be administered within 3 h of symptom onset 3,. The vast majority of stroke patients are not evaluated in this limited time window and although recent literature supports a modest benefit.5 h from symptom onset 9, 10, under 5 of stroke patients 30 currently receive tPA 4,.

Recently, laser technology has been applied to acute ischemic stroke. This noninvasive technique uses near-infrared wavelengths applied to the scalp within 24 h of symptom onset. The mechanism is incompletely understood but may involve increased mitochondrial adenosine triphosphate production. Animal models demonstrated safety and efficacy night warranting randomized controlled trials in humans. Nest-1 (phase 2) and nest-2 (phase 3) confirmed the safety of transcranial laser therapy, although efficacy was not found in nest-2. Pooled analysis of nest1 and nest-2 revealed a significantly improved success rate in patients treated with laser therapy. Further phase 3 testing is planned and may create a new paradigm for the treatment of acute ischemic stroke.

Finally, any quantitative analysis of scientific publication must take into account the universal trends in scientific publication (how much of what you are looking at is just a reflex of an overall growth in science). If we look at the publication trends on red light therapy, there is a steep rise in publication around the year 2000 and soon after that (figs 1-3). If we compare that with patent data on red light therapy devices (fig 4 we observe that they peak more or less around the period when publications start to increase.

The amount of confusion concerning the subject, now, is alarming. There are people reporting ultra-violet light applications in the red light forums, when violet and ultra-violet light are in the opposite side of the visible light spectrum and have very different interaction with biomolecules. There are several devices available in the market, from cheap to expensive. Most can be used at home, but there are a few sophisticated systems that are used in specialized alternative medicine clinics. At the scientific level, there is not much we can positively say. As I will elaborate in the following items, most research measures a phenomenon, or uses by-proxy methods to address possible causes, just to conclude that the mechanism is unknown.

Red light application seems to be beneficial to certain injuries and pathological conditions but the panacea claims currently made are not yet backed by research. When we think about research on a certain subject and what exactly does more research mean, we must consider a few aspects of the nature of scientific production. First, that an increase in published evidence always results from a combination of the scientific communitys interest, public interest as reflected, for example, in public policies or public opinion expression, and availability of research funds and infra-structure. Research on hiv, for example, was instantly increased once it was perceived as a major public health threat. Most other issues on medical research, which cologne is mostly applied, follow the interplay of what we call market pull and technology (and science) push. Like the proverbial egg and chicken dilemma, sometimes it is hard to discern between what factor was determinant: the need for a certain medical innovation or the interest of the scientific and technology research community in pursuing that route.

What can fahrenheit be more tempting to try? Thats where we come. Massive marketing and insufficient scientific evidence are a bad combination. Let us examine what current research can positively confirm concerning the benefits of red light therapy and whether it is safe. Table of Contents, the preferred technical term for red light therapy is Low level Laser Therapy (lllt but other terms like low-power laser therapy (lplt creme soft laser therapy, low-intensity laser therapy, low-energy laser therapy, cold laser therapy, bio-stimulation laser therapy, photobiomodulation, photo-biotherapy, therapeutic laser, and. The procedure consists of exposing an area of the body to low levels of red and near infrared light. The term low specifies that the light densities are low compared to medical laser applications such as surgical cutting or thermal coagulation. Those who claim lllt is responsible for a wide range of beneficial clinical responses believe that its effect goes beyond local heat application. I examined a few user forums and, apart from joint pains, musculoskeletal issues and arthritis, there is not much consensus about treatment benefits (Energeticforum and realself).

Although pain is still an application, up there on the first page you will see rejuvenation. Red lightanti-aging render around.6 million results on google. As with most things that grow too fast into fads, the red light became a panacea: claimed benefits include faster wound healing, immune boosting, treatment for hair loss, depression, skin disorders, arthritis and even cancer. A noninvasive, relatively cheap and easy to use treatment for some of the conditions that cause the greatest suffering modern humans face. As Hahm and colaborators ( 22 ) suggest, it was the non-invasiveness and patient acceptance of red light treatment that keeps its use, in spite of not being fda approved or covered by insurance companies.

Many of the big commercial fads today are related to the beauty industry. The beauty industry goes beyond cosmetics. It brings together all economic niches that offer consumers goods and services to look better. That goes from fashion to fitness, from food to cosmetic surgery, and much more. In an aging world, or in a world where actual consumers are proportionately older, nothing is commercially hotter than the anti-aging industry. An inconspicuous device that was used mostly for minor joint injuries a couple of decades ago made collagen it there: the red light. We had one of those at home: my mother left me for a couple of minutes under it when I was sore after a fight.
