Laser and Sports Medicine in Plastic and Reconstructive Surgery.

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. 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: Diode laser therapy was indicated for traumatic skin ulcers from sport activities and traffic accidents which were resistant to conservative treatment. The diode laser system with a wavelength of 830 nm. and output power of 150or 1000mw in continuous wave 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 was used successfully for the rapid enhanced healing […]

Texas Chiropractic Board Approves Low-Level Laser Therapy

MISSOURI CITY, Texas – April 10, 2002 – The Texas Board of Chiropractic Examiners has determined that MicroLight Corporation of America’s ML 830® low-level laser is within the scope of chiropractic care, the company announced today.   “This represents a major breakthrough in the treatment of Carpal Tunnel Syndrome in the chiropractic profession,” said MicroLight President Mike Barbour. “This will allow more than 4,000 chiropractors in the state of Texas access to the ML 830® patented laser technology.” MicroLight is the only company that has received FDA clearance to market low-level laser therapy for non-surgical treatment of Carpal Tunnel Syndrome, or CTS. CTS is the No. 1 repetitive-stress injury problem in the workforce, costing the U.S. health care industry more than $10 billion annually.

Usually the healing process of bone is slower than that of soft tissue. Effects of LLLT on bone are still controversial. This paper reports observations on the effect of LLLT on bone healing. The amount of newly formed bone after 830nm laser irradiation of surgical wounds created in the femur of rats was evaluated morphometricaly. Forty Wistar rats were divided into four groups: group A (12 sessions, 4.8J/cm2 per session, 28 days); group C (three sessions, 4.8J/cm2 per […]

Comparison between low level laser therapy, transcutaneous electro-neural stimulation, visible incoherent polarised light and placebo in the treatment of lateral epicondylitis: A pilot clinical study on 120 patients

Simunovic Z and Trobonjaca T Lasers in Surgery and Medicine (2002) Supplement 14, Atlanta, Georgia   The aim of this pilot study was to compare the efficacy of Low Level Laser therapy (LLLT), Transcutaneous Electro-Neural Stimulation (TENS), visible incoherent polarized (VIP) light and placebo in the treatment of lateral epicondylitis-tennis elbow. The patient population (n=120) was randomly allocated into four groups according to treatment applied. The therapy lasted three weeks per each treatment modality, where total number of treatments per patient was twelve (5+4+3 per three weeks). LLLT was applied as trigger points technique in all patients, using an infrared diode laser in a dosage of 4 J/point. TENS was applied using gummy plates in the same sizes and by exactly measuring the amount of mA, mV and Hertz in all patients. VIP light was applied in a dosage of 4/J.cm2 . Placebo was applied by using a laser device with no active laser emission. All patients suffered from chronic form of lateral epicondylitis, with x-ray proved no changes on the cervical spine. The outcome measurement was focused on the level of pain relief, estimated according to the Visual Analogue Scale (VAS). The results have demonstrated that the highest percentage […]

Laser’s effect on bone and cartilage change induced by joint immobilization: an experiment with animal model.

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.
