Abstract

Objective: Red light phototherapy is known to stimulate cell proliferation in wound healing. This study in- vestigated whether low-level light therapy (LLLT) would promote tumor growth when pre-existing malignancy is present. Background data: LLLT has been increasingly used for numerous conditions, but its use in cancer patients, including the treatment of lymphedema or various unrelated comorbidities, has been withheld by practitioners because of the fear that LLLT might result in initiation or promotion of metastatic lesions or new primary tumors. There has been little scientific study of oncologic outcomes after use of LLLT in cancer patients. Methods: A standard SKH mouse nonmelanoma UV-induced skin cancer model was used after visible squa- mous cell carcinomas were present, to study the effects of LLLT on tumor growth. The red light group (n = 8) received automated full body 670 nm LLLT delivered twice a day at 5 J/cm2 using an LED source. The control group (n = 8) was handled similarly, but did not receive LLLT. Measurements on 330 tumors were conducted for 37 consecutive days, while the animals received daily LLLT. Results: Daily tumor measurements demonstrated no measurable effect of LLLT on tumor growth. Conclusions: This experiment suggests that LLLT at these parameters may be safe even when malignant lesions are present. Further studies on the effects of photo- irradiation on neoplasms are warranted.

Exposure to Near Infrared Light Alters the Temporal Expression of Bone Morphogenetic Proteins: Implications for the Enhancement of Fracture Healing

 "Recently, investigators have shown that treatment of fractures with near infrared light (NIR) increases bone callus formation and bone mineral density in the early stages of fracture healing. Our lab recently showed that NIR exposure decreases osteoblast apoptosis (cell death) and promotes cell proliferation."

Photomedicine, Not Opioids, for Chronic Pain
Narda G. Robinson, DO, DVM, MS, FAAMA

"Although many who practice photomedicine in clinical settings know that light therapy can provide rapid, safe, and noninvasive analgesia, most medical practitioners remain unaware and/ or unconvinced of its value. They live in the dark, not realizing that photomedicine effectively treats a variety of nociceptive and neuropathic pain problems from head to toe, all with a notably low risk profile. Whereas opioids lead to addiction, photomedicine leads to healing. Photobiomodulation repairs tissue, relaxes muscles, reduces inflammation and edema, and restores circulation as well as nerve function to more normal levels. No opioid can match the reparative value of light. It is time for photomedicine practitioners to educate the public and the medical profession about this valuable, cost-effective, and well-received treatment option. You can bet the drug companies will not."

Wow, this is very interesting.  Both Laser and LED had very similar effects on increased healing!  
Photobiomodulation (Laser and Led) On Sternotomy Healing in Hyperglycemic and Normoglycemic Patients Who Underwent Coronary Bypass Surgery with Internal Mammary Artery Grafts: A Randomized, Double-Blind Study with Follow-Up
Andre´ a Conceic¸ a˜ o Gomes Lima, PT, MS, Gilderlene Alves Fernandes, PT, MS Raimundo de Barros Arau´ jo, MD, Isabel Clarisse Gonzaga, PT, MS, Rauirys Alencar de Oliveira, PT, PhD, and Renata Amadei Nicolau, PhD

"The mechanisms involved in enhanced tissue repair with LLLT and LED therapy include an increase in the number of dividing cells and increases in the levels of inducible nitric oxide synthase, keratinocyte growth factor, and keratinocyte growth factor receptor, which may facilitate earlier and thicker re-epithelization.33 At doses of 5–6 J/cm2, LLLT can stimulate the production of bFGF, a multi-functional polypeptide that supports fibroblast proliferation and differentiation. Further, high doses suppress bFGF.34 The effects of the laser and LED sources were comparable when equal therapeutic doses of light were applied. The result was an improved healing process, which can be observed on sternotomy incisions after a protocol of irradiation."

 Study on Light Emitting Diode Treatments in Traumatic Brain Injury
Margaret A. Naeser, Ph.D., L.Ac.,1,2 Anita Saltmarche, R.N., M.H.Sc.,3 Maxine H. Krengel, Ph.D.,1,2 Michael R. Hamblin, Ph.D.,4,5,6 and Jeffrey A. Knight, Ph.D.1,2,7

Objective: Two chronic, traumatic brain injury (TBI) cases, where cognition improved following treatment with red and near-infrared light-emitting diodes (LEDs), applied transcranially to forehead and scalp areas, are presented. Results: Seven years after closed-head TBI from a motor vehicle accident, Patient 1 began transcranial LED treatments. Pre-LED, her ability for sustained attention (computer work) lasted 20 min. After eight weekly LED treatments, her sustained attention time increased to 3 h. The patient performs nightly home treatments (5 years); if she stops treating for more than 2 weeks, she regresses. Patient 2 had a history of closed-head trauma (sports/military, and recent fall), and magnetic resonance imaging showed frontoparietal atrophy. Pre-LED, she was on medical disability for 5 months. After 4 months of nightly LED treatments at home, medical disability discontinued; she returned to working full-time as an executive consultant with an international technology consulting firm. Neuropsychological testing after 9 months of transcranial LED indicated significant improvement (þ1, þ2SD) in executive function (inhibition, inhibition accuracy) and memory, as well as reduction in post-traumatic stress disorder. If she stops treating for more than 1 week, she regresses. At the time of this report, both patients are continuing treatment. Conclusions: Transcranial LED may improve cognition, reduce costs in TBI treatment, and be applied at home.

This study was done with humans, but we all know that when we are bringing back our animal partners from injury,
they can get sore too!!  I think it can easily be applied to our equines and canines in rehabilitation!
