How laser light helps cells repair themselves CAN gentle doses of laser light help cells to heal?” THE NEW SCIENTIST, October 11-15, 2003 How laser light helps cells repair themselves CAN gentle doses of laser light help cells to heal? The technique is sometimes used to treat problems such as tinnitus and joint pain, but with no explanation for how these therapies work, there is scepticism over whether the effect is real. Now a physicist has come up with evidence that the physical forces generated by low-energy laser beams may switch on cells’ repair mechanisms. This will support the growing body of evidence that laser therapy is beneficial. At the Joint International Laser Conference in Edinburgh, UK, last month, researchers reported promising results for fields as diverse as IVF and spinal injury. For example, rats with damaged spinal cords made a better recovery if their wound was illuminated with near-infrared laser light, reported Kimberly Byrnes of the Uniformed Services University of Health Sciences in Bethesda, Maryland. Her team found that in light- treated rats, levels of interleukin-6, which is involved in inflammation, were only 1 per cent of the levels in a control group of rats. But Byrnes does […]
Sawazaki I, Ribeiro M S, Mizuno L T et al. Laser Surg Med. Abstract issue 2002, abstract 301 The effect of toluidine blue and laser in combination has been studied by Sawazaki. Eight patients with inflammatory fibrous hyperplasias caused by ill-fitting dentures were selected for the study. Each hyperplasia was randomly divided into three areas. One was surgically removed without any treatment; one was treated by a 670 nm laser, 15 mW, 8 J/cm2 and then removed. The third part was dyed with TBO, and laser treated in the same way as part two. Mast cell degranulation in the control specimens was average 49´%, in the laser specimens 87% and in the combined TBO/laser specimens 88%. With these parameters the TBO did not have any additional effect.
The Norwegian physiotherapist Jan M Bjordal published his thesis .Low level laser therapy in shoulder tendinitis/bursitis, epicondylalgia and ankle sprain. in 1997, at the Division of Physiotherapy Science, University of Bergen. It has also been published in Physical Therapy Reviews. 1998; 3: 121-132. Here is the Conclusion of the thesis: .A systematic review has been performed on the effect of LLLT for three diagnoses. LLLT was evaluated on similar criteria for methodological assessments of trials as previously established for medical interventions. No evidence was found to indicate that randomized controlled trials on LLLT for tendinitis/bursitis of the shoulder, lateral epicondylalgia and ankle sprains were methodologically inferior to RCTs on medical interventions. The clinical effects of LLLT were found to be supported by scientific evidence regarding short (0-4 weeks) and medium term (<3 months) efficacy for subacute or chronic lateral epicondylitis, and short term efficacy (>3 months) for subacute or chronic lateral epicondylitis, and short term efficacy (> 3 months) for subacute or chronic shoulder tendinitis/bursitis. The evidence of effect from LLLT for acute ankle sprain in inconclusive, although there seems to be a slight tendency in favor of LLLT. Adverse effects of LLLT are rarely seen and only in […]
Sanseverino NTM, Sanseverino CAM, Ribeiro MS et al. The Journal of Laser Therapy MILLENNIUM EDITION • VOLUMES 12 & 13 Lasers in Medicine and Surgery (2002) Supplement 14, Atlanta, Georgia. The improved outcome of laser therapy, if higher doses are given, is documented in the study by Sanseverino 10 patients with pain and limitation of movements of the jaw were treated by 785 nm GaAIAs laser, dose 45 J/cm2. The joint and tender points in the masticatory and otherwise involved muscles was applied three times per week during three weeks. A control group of 10 patients was given sham laser therapy. The evaluation was performed through subjective pain assessment and measurement of the movements of the jaw. There was a significant improvement in the laser group only.
By Jeffrey M. Nelson, MD and Karen P. Nelson, MA The cell is a machine driven by energy… In every medical tradition before ours, healing was accomplished by moving energy. – Albert von Szent-Györgyi (1967) Light energy has been used for healing since the earliest recorded medical history, but has gone out of favor in Western medicine with the advent of the existing paradigm of a more surgical and pharmacological basis. Recently, a shift in thinking has been emerging with an explosion of research, exploration and utilization of energy medicine modalities such as micro-current stimulators, bone growth stimulators, broad-spectrum multiple frequency Tesla coil devices, and low-level or cold lasers. Despite years of research demonstrating the benefits of low-level laser therapy (LLLT) as a modality for wound healing, Western medicine, and its adjunct professions, have been slow to adopt this technology. LLLT has been an essential part of therapy for practitioners around the world for almost 20 years, but it is only recently catching on in the United States. Still, the vast majority of students of medicine and allied health practices in this country are not being taught its efficacy and use. It’s time we opened our eyes to the […]
