Asagai reports on the use of GaAlAs (100 mW) laser treatment in a group of 1000 patients with cerebral palsy.

Proc. 2nd Congress World Assn for Laser Therapy, Kansas City, September 1998; p. 99-100.   The laser reduces muscle spasm and increases the mobility of the muscles. Although the duration of the LLLT effect was limited to one to several hours, it can be applied in conjunction with conventional functional therapies, thereby enhancing the effects of the latter.

Effects of visible NIR low intensity laser on implant osseointegration in vivo.

Blay A, Blay C C, Groth E B et al. Surg Med Abstract Issue. Am Soc Laser Med Surg Abstracts, 2002   The effects of 680 and 830 nm lasers on osseointegration was studied by Blay. 30 adult rats were divided into three groups; two laser groups and one control. The rats in the two laser groups had pure titanium Frialit-2 implants implanted into each proximal metaphysis of their respective tibias, inserted with a 40 Ncm torque. The initial stability was monitored by means of a resonance frequency analyzer. Ten irradiations were performed, 48 hours apart, 4 J/cm2 on two points, starting immediately after surgery. Resonance frequency analysis indicated a significant difference between frequency values at 3 and 6 weeks, as compared to control. At 6 weeks the removal torque in the laser groups was much higher than in the control group.

The clinical efficacy of low-power laser therapy on pain and function in cervical osteoarthritis.

Oezdemir F, Birtane M, Kokino S Department of Physical Therapy and Rehabilitation, Medical Faculty of Trakya University, Edirne, Turkey. PMID: 11434469 [PubMed – indexed for MEDLINE] Clinical Rheumatology (2001) 20(3): 181-184   Pain is a major symptom in cervical osteoarthritis (COA). Low-power laser (LPL) therapy has been claimed to reduce pain in musculoskeletal pathologies, but there have been concerns about this point. The aim of this study was to evaluate the analgesic efficacy of LPL therapy and related functional changes in COA. Sixty patients between 20 and 65 years of age were clinically and radiologically diagnosed COA were included in the study. They were randomized into two equal groups according to the therapies applied, either with LPL or placebo laser. Patients in each group were investigated blindly in terms of pain and pain-related physical finds, such as increased paravertebral muscle spasm, loss of lordosis and range of neck motion restriction before and after therapy. Functional improvements were also evaluated. Pain, paravertebral muscle spasm, lordosis angle, the range of neck motion and function were observed to improve significantly in the LPL group, but no improvement was found in the placebo group. LPL seems to be successful in relieving pain and improving […]

Low level laser therapy can be effective for tendinitis: a meta-analysis.

Bjordal J M.   A literature search identified 77 randomized clinical trials with LLLT, of which 18 included tendinitis. Three trials were excluded for lack of placebo control, of which one was comparative, another lacked patients with tendinitis in the treatment group, while the last unwittingly gave the placebo group active treatment. Four trials used too high power density or dose, and three did not expose the skin directly overlying the injured tendon. The remaining eight trials were included in a statistical pooling, where the mean effect of LLLT over placebo in tendinitis was calculated to 29.5% (19.5-39.0). LLLT with optimal treatment procedure/parameters can be effective in the treatment of tendinitis.

The Journal of Laser Therapy. Vol.13. World Association of Laser Therapy. 2000.   During the last decade, it was discovered that low-power laser irradiation has stimulatory effects on bone cell proliferation and gene expression. The purposes of this review are to analyze the effects of low- power laser irradiation on bone cells and bone fracture repair, to examine what has been done so far, and to explore the additional works needed in this area. The studies reviewed show how laser therapy can be used to enhance bone repair at cell and tissue levels. As noted by researchers, laser properties, the combinations of wavelength and energy dose need to be carefully chosen so as to yield bone stimulation.
