Junichiro Kubota M.D. Department of Plastic and Reconstructive Surgery, Kyorin University School of Medicine, Tokyo, Japan. Abstract from II Congress of the Internat. Assn for Laser and Sports Medicine, Rosario, Argentina, March 10-12, 2000. Flap survival with diode laser therapy: Skin flap or graft surgery are major procedures in Plastic and Reconstructive Surgery. Skin flap necrosis has been a problem for us. The author reported on the enhanced blood flow following the low reactive laser therapy in skin flaps. The 830 nm diode laser (20 – 60 mw) irradiated flaps showed a greater perfusion, a greater number of blood vessels, and a higher rate of survival areas than the control flaps in the rat models and clinical cases. Improvement of wound healing with diode laser therapy: The diode laser therapy was indicated for traumatic skin ulcers received from sport activities and traffic accidents which had proved resistant to conservative treatment. The diode laser system has a wavelength of 830 nm. and output power of 150or 1000mw in continuous wave. The diode laser was applied with the non-contact method to the area on the wound for one minute once a day every day during the treatment period. The diode laser […]
J.M. Bjordal, C. Couppe University of Bergen, Dept. Physiotherapy Science, Bergen, Norway Abstract from the 7th International Congress of European Medical Laser Association, Dubrovnik, Croatia, June 2000. What is optimal dose, power density and timing for low level laser therapy in tendon injuries? A review of in vitro and in vivo trials Purpose: To investigate the effect of different laser treatment parameters on fibroblast inflammation and production of collagen fibers. Material : Controlled in vitro or in vivo trials with low level laser therapy (LLLT) Method : Literature search for trials published after 1980 using LLLT on Medline, Embase, Cochrane Library and handsearch of physiotherapy journals in English and Scandinavian languages. Optimal treatment parameters regarding timing, treatment frequency, dose and power density at target tissue were synthesized. Results : The literature search identified 31 controlled trials with LLLT on collagen tissue. Three in vitro trials were performed on stretch-induced and inflammation in fibroblast cultures and five in vitro trials were performed on collagen production. Optimal dose and power density for inhibition of prostaglandin PGE2 and interleukin 1- beta production was found to be 3.2-6.3 J/cm2 and 5.3 mW/cm2 measured at the target fibroblast cells after 5 days of irradiation.

Kesava Reddy, Ph.D., Department of Physical Therapy and Rehabilitation Sciences, University of Kansas Medical Center, Kansas City, KS 66160-7601, USA The Journal of Laser Therapy. Vol. 12. World Association of Laser Therapy. 2000 Connective tissue injuries, such as tendon rupture and ligamentous strains, are common. Unlike most soft tissues that require 7-10 days to heal, primary healing of tendons and other dense connective tissues take as much as 6 – 8 weeks during which they are inevitably protected in immobilization casts to avoid re-injury. Such long periods of immobilization impair functional rehabilitation and predispose a multitude of complications that could be minimized if healing is quickened and the duration of cast immobilization reduced. In separate studies, we tested the hypothesis that early function, ultrasound, 632.8 nm He-Ne laser, and 904 nm Ga-As laser, when used singly or in combination, promote healing of experimentally severed and repaired rabbit Achilles tendons as evidenced by biochemical, biomechanical, and morphological indices of healing. Our results demonstrate that: (1) appropriate doses of each modality, i.e., early functional activities, ultrasound, He-Ne and Ga-As laser therapy augment collagen synthesis, modulate maturation of newly synthesized collagen, and overall, enhance the […]
Lilic Alen, physiotherapist; Kozlevcar Zivec Maja, dr. med. spec.fiz.reh.med.; Marcan Radoslav, dr.med., spec.ortop FIZIO, Ilirska Bistrica, Slovenija, Iskra Medical, Ljubljana, Slovenija, Ortopedska bolnisnica Valdoltra, Slovenija In the present article we will review different kind of injuries in the alpine ski sport and we will concentrate on the injuries of the ligamentar part of the knees and meniscs in slovenian ski team. After the description of the injuries follows detailed presentation of the rehabilitational procedures from the first day of the injury till the return in to the competition arena. We will try to explain the modalities of the rehabilitational procedures and their influence in the tissues, their main and side effects. Our main attention will be focused to the use of the biostimulative laser of higher power – 1,2 W and wave length of 830 nm and it’s influence on the velocity of recovery in the patients and their success in following competitions.
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.
