Bjordal JM et al PMID: 18510742 [PubMed – as supplied by publisher] BMC Musculoskelet Disord. 2008 May 29;9(1):75 ABSTRACT: BACKGROUND: Recent reviews have indicated that low level level laser therapy (LLLT) is ineffective in lateral elbow tendinopathy (LET) without assessing validity of treatment procedures and doses or the influence of prior steroid injections. METHODS: Systematic review with meta-analysis, with primary outcome measures of pain relief and/or global improvement and subgroup analyses of methodological quality, wavelengths and treatment procedures. RESULTS: 18 randomised placebo-controlled trials (RCTs) were identified with 13 RCTs (730 patients) meeting the criteria for meta-analysis. 12 RCTs satisfied half or more of the methodological criteria. Publication bias was detected by EggerA’s graphical test, which showed a negative direction of bias. Ten of the trials included patients with poor prognosis caused by failed steroid injections or other treatment failures, or long symptom duration or severe baseline pain. The weighted mean difference (WMD) for pain relief was 10.2 mm [95% CI: 3.0 to 17.5] and the RR for global improvement was 1.36 [1.16 to 1.60]. Trials which targeted acupuncture points reported negative results, as did trials with wavelengths 820, 830 and 1064 nm. In a subgroup of five trials with […]
– Nata News Magazine, October 2002Bv Valerie Hunt Two certified athletic trainers are among a handful of people in the United States comprising an initial group of professionals certified to use a new low-Ievel laser. The device, they say, offers amazing relief for people with carpal tunnel syndrome, and it also represents a wealth of research opportunity. Doug Johnson, ATC, co-owner of Sports and Industrial Rehab in Taylor, MI, and Ray Maleyko, ATC, a Sports and Industrial Rehab employee, both are certified to use the Microlight 830 low- level laser, which gained FDA approval in February for treatment of carpal tunnel syndrome. The ML 830 remains the only laser with FDA approval for CTS, and fewer than 30 of the machines exist currently, although the Texas-based manufacturer is working to fill a growing demand for the tool. “Canada has had this technology since 1994, but the United States is just now getting it,” Johnson said. “It is scary how well this laser works. It’s the first thing in therapy that can actuallv help heal the tissue.” Getting results – Johnson began following the development of the Microlight 830 laser after its clinical trials years ago.

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.
