Low Level Laser Therapy LLLT / Cold Laser Literature watch for June 2012
29 papers published in June for you to review including: a meta-analysis of LLLT on joint pain (one of the best results come from an LED study, but this paper refers to it as a laser!), an RCT on hypothyroidism induced by chronic autoimmune thyroiditis, a review of 9 papers on xerostomia and much more.
Meta-Analysis of Pain Relief Effects by Laser Irradiation on Joint Areas.
Jang, H, Lee H
Department of Information and Communications, Gwangju Institute of Science and Technology , Gwangju, Republic of Korea.
Abstract Background: Laser therapy has been proposed as a physical therapy for musculoskeletal disorders and has attained popularity because no side effects have been reported after treatment. However, its true effectiveness is still controversial because several clinical trials have reported the ineffectiveness of lasers in treating pain. Methods: In this systematic review, we investigate the clinical effectiveness of low-level laser therapy (LLLT) on joint pain. Clinical trials on joint pain satisfying the following conditions are included: the laser is irradiated on the … Continue reading

Short-term clinical and osteoimmunological effects of scaling and root planing complemented by simple or repeated laser phototherapy in chronic periodontitis.

Departamento de Estomatologia III, Facultad de Odontologia, UCM, Madrid, Spain.
The aim of this study was to evaluate the clinical, anti-inflammatory, and osteoimmunological benefits of the single (PT) and repeated laser phototherapy (rPT) as an adjunctive treatment of inflamed periodontal tissue. Twenty-seven patients with chronic periodontitis were randomly divided into three groups of nine patients each in order to undergo scaling and root planing (SRP), SRP followed by one session of adjunctive PT (Day 1; SRP + PT), or SRP followed by adjunctive repeated PT five times in 2 weeks (Days 1, 2, 4, 7, and 11; SRP + rPT). … Continue reading

Low Level Laser Therapy LLLT / Cold Laser Literature watch for April 2012
32 LLLT papers for you this month including: Another RCT for chemoradiotherapy induced oral mucositis showing reduced severity and duration, another RCT showing how IR LEDs increase microcirculation in healthy subjects, and this surprised me; Laser-assisted nasal decolonization of Staphylococcus aureus including MRSA. de Sousa explores which wavelengths change bacterial morphology, Cepera et al show faster bone regeneration with LLLT after rapid maxillary expansion, LLLT gets a mention for onychomycosis which I am yet to be convinced about (though anecdotal reports are enthusiastic), and a tendinopathy trial gone wrong.

When the right dose goes wrong
It must gall to have performed a controlled clinical trial for a year only to find at the end that your physics department had adjusted the active laser such that it did not perform as planned.
The trial by Tumilty et al (TITLE: Clinical effectiveness of low-level laser therapy as an adjunct to eccentric exercise for the treatment of Achilles’ tendinopathy: a randomized controlled trial) set out to deliver twelve treatments of 100mW/cm2 of 810nm laser for 30 seconds to 6 points (3J per point) on the Achilles tendon over a 4 week period, but something went wrong and the treatment failed to have any significant effect over placebo.
What went wrong: The university physics dept had been asked to adjust the 810nm 100mW, 2.5W/cm2 power density to 100mW/cm2. They achieved the 100mW/cm2 by expanding the beam, but unfortunately they also decided to reduce the aperture to 0.07cm2. This had two unfortunate effects, the 100mW beam became reduced to 7mW and the beam did not adequately cover the pathology. So only 0.21J was delivered and only a tiny part of … Continue reading
