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 […]
By Jeffrey M. Nelson, MD and Karen P. Nelson, MA The cell is a machine driven by energy… In every medical tradition before ours, healing was accomplished by moving energy. – Albert von Szent-Györgyi (1967) Light energy has been used for healing since the earliest recorded medical history, but has gone out of favor in Western medicine with the advent of the existing paradigm of a more surgical and pharmacological basis. Recently, a shift in thinking has been emerging with an explosion of research, exploration and utilization of energy medicine modalities such as micro-current stimulators, bone growth stimulators, broad-spectrum multiple frequency Tesla coil devices, and low-level or cold lasers. Despite years of research demonstrating the benefits of low-level laser therapy (LLLT) as a modality for wound healing, Western medicine, and its adjunct professions, have been slow to adopt this technology. LLLT has been an essential part of therapy for practitioners around the world for almost 20 years, but it is only recently catching on in the United States. Still, the vast majority of students of medicine and allied health practices in this country are not being taught its efficacy and use. It’s time we opened our eyes to the […]
Akai M, Usuba M, Maeshima T, Shirasaki Y, Yasuoka S Lasers Surg Med. 1997. 21(5): 480-4. The influence of low-level (810 nm) laser on bone and cartilage during joint immobilization was examined. The hind limbs of 42 young Wistar rats were immobilized at the knee joint. They were sorted into three groups 1 wk after operation; irradiance 3.9 W/cm2, 5.8 W/cm2, and sham treatment. After 6 treatments for another 2 weeks both hind legs were prepared for 1) indentation of the articular surface of the knee (stiffness and loss tangent), and for 2) dual energy X-ray absorptiometry (bone mineral density) of the focused regions. The indentation test revealed preservation of articular cartilage stiffness with 3.9 and 5.8 W/cm2 therapy. Low level laser treatment may possibly prevent biomechanical changes by immobilization.

Low energy lasers are widely used to treat a variety of musculoskeletal conditions including fibromyalgia, despite the lack of scientific evidence to support its efficacy. A randomized, single-blind, placebo-controlled study was conducted to evaluate the efficacy of low-energy laser therapy in 40 female patients with fibromyalgia. Patients with fibromyalgia were randomly allocated to active (GaAs) laser or placebo laser treatment daily for two weeks except weekends. Both the laser and placebo laser groups were evaluated for the improvement in pain, number of tender points, skinfold tenderness, stiffness, sleep disturbance, fatigue, and muscular spasm. In both groups, significant improvements were achieved in all parameters (p<0.05) except sleep disturbance, fatigue and skinfold tenderness in the placebo laser group (p>0.05). It was found that there was no significant difference between the two groups with respect to all parameters before therapy whereas a significant difference was observed in parameters as pain, muscle spasm morning stiffness and tender point numbers in favour of laser group after therapy (p<0.05). None of the participants reported any […]
