Bjordal J M, Couppe´ C, Ljunggren E University of Bergen, Section of Physiotherapy Science, 5020 Bergen, NORVEGE Willemoes gade 61, 4.sal, 2100, Copenhagen, DANEMARK Physical Therapy Reviews (2001) 6: 91-99 To investigate whether low-level laser therapy can reduce pain from tendinopathy, the authors performed a review of randomized placebo-controlled trials with laser therapy for tendinopathy. Validity assessment of each trail was done according to predefined criteria for location-specific dosage and irradiation of the skin directly overlying the affected tendon. The literature search identified 78 randomised control trials of which 20 included tendinopathy. Seven trials were excluded for not meeting the validity criteria on treatment procedure and trial design. 12 of the remaining 13 trials investigated the effect of laser therapy for patients with subacute and chronic tendinopathy and provided a pooled mean effect of 21%. If results from only the nine trials adhering to assumed optimal treatment parameters wereincluded, the mean effect over placebo increased to 32%. Laser therapy can reduce pain in subacute and chronic tendinopathy if a valid treatment procedure and location-specific dose is used.
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 […]

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 […]
