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

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.

The Biological Effects of Laser Therapy and Other physical Modalities on Connective Tissue Repair Processes

Chukuka S. Enwemeka, P.T., Ph.D., FACSM, G. 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 […]

Wound healing of animal and human body sport and traffic accident injuries using low-level laser therapy treatment: a randomized clinical study of seventy-four patients with control group

Simunovic Z, Ivankovich AD, Depolo A. Department of Anesthesiology, La Caritá Medical Center, Laser Center, Locarno, Switzerland. info@lasermedico.ch PMID: 11800105 [PubMed – indexed for MEDLINE] Journal of Clinical Laser Medicine and Surgery (2000) Apr;18(2):67-73   The main objective was to assess the efficacy of low level laser therapy (LLLT) on wound healing in rabbits and humans. The initial research was a randomized controlled animal study, to evaluate the effects of laser irradiation on the healing of surgical wounds in rabbits. The application of LLLT on the human body is analogous to those of similar physiologic structure in animal tissue. This study was continued on humans, 74 patients with injuries to the following anatomic locations: ankle and knee, bilaterally, Achilles tendon; epicondylitis; shoulder; wrist; interphalangeal joints of hands, unilaterally. All patients has surgery prior to LLLT. Two laser devices were used: infrared diode laser (GaAIAs) 830 nm continuous wave for treatment of trigger points (TPs) and HeNe 632.8 nm combined with diode laser 904 nm pulsed wave for scanning procedure. Both were applied as monotherapy during the study. Results were observed and measured according to these clinical parameters: redness, heat, pain, swelling and loss of function, and finally submitted to statistical […]

Health Alert: Laser Treatment for Carpal Tunnel Syndrome

By KYW NewsRadio PHILADELPHIA – Oct. 16, 2002 – Medical Specialist Stephanie Stahl reports there is a new alternative for those who suffer from Carpal Tunnel Syndrome.   Repetitive hand movement causes tendons in the hand and wrist to swell, pressing on a nerve. That pressure causes pain, numbness, and tingling, resulting in Carpal Tunnel Syndrome – a condition that has become the leading cause of disability in this country. “You’re constantly saying ‘what’s the matter with my hands?’ You’re shaking them, you’re rubbing them – just doing anything and everything you can to keep them awake,” explains local sufferer Kathy Kish. Kish says that is how she felt until she underwent high-tech treatment with the ML830® Laser. Dr. Mark Brown, a chiropractor, explains how it works: “It just sends bursts of laser light into the tissue and on a cellular level they respond like a bud that would open up to a flower – just speeds up the healing process.” Brown says the laser is unlike other lasers because it doesn’t burn the skin, and claims the treatment “works very, very well” yielding “fantastic results.” Kish agrees, telling Stahl the treatment enabled her to sleep through the night for […]
