1: Akersberga Health Care Centre,
2: Danderyd University Hospital, Danderyd, and
3: Vaxholm Health Care Centre, Stockholm, Sweden.

The purpose of this randomised, double-blind study was to examine the effect of GaAs laser therapy for tendonitis and myofascial pain in a sample from the general population of Akersberga in the northern part of Greater Stockholm.

176 patients (of an original group of 200) completed the scheduled course of treatment. The patients were assigned randomly to either a laser group (92 patients, of whom 74 had tendonitis, completed the study) or a placebo group (84 patients, of whom 68 had tendonitis, completed the study). All 176 patients received six treatments during a period of 3-4 weeks. Their pain was estimated objectively using a pain threshold meter, and subjectively with a visual analogue scale before, at the end of, and four weeks after the end of treatment.

Laser therapy had a significant, positive effect compared with placebo measured from the first assessment to the third assessment, four weeks after the end of treatment. Laser treatment was most effective on acute tendonitis. 

LLLT using a diode laser in successful treatment of a herniated lumbar/sacral disc, with magnetic resonance imaging (MRI) assessment

Tatsuhide Abe. Abe Orthopaedic Clinic Futuoka City Fukuoka Prefecture Japan X12′ A 40- year-old woman presented at the Abe Orthopedic Clinic with a 2-year history of lower hack pain and pain in the left hip and leg diagnosed as a ruptured disc between the 5th lumbar/lst sacral vertebrae. The condition had failed to respond to conventional treatment methods including pelvic traction, nonsteroid anti-inflammatory drugs and aural block anesthetic injections. MRI scans were made of the affected disc, showing it protruding on the left side through the aural membrane. The

Mechanisms of the analgesic effect of therapeutic lasers in vivo

L Navratil (1) and I Dylevsky (2) 1: Outpatient Department of Radiobiology, Institute of Biophysics, First Medical Faculty, and 2: Department of Functional Anatomy, Second Medical Faculty and Faculty of Physical Education Charles University, Prague, Czech Republic The analgesic effects in the course of application of therapeutic lasers to affected tissue have been described in a number of works in the literature. Although a few scientific- based reports have appeared, those on laser-induced analgesia are mainly clinical works describing the

Mechanistic approach to GaAIAs diode laser effects on production of reactive oxygen species from human neutrophils as a model for therapeutic modality at cellular level

Makoto Yamaya*, Chiyuki Shiroto’, Hiroki Kobayashi*, Shinji Naganuma*, Jyuichi Sakamoto*, Koh-Jun Suzuki*, Shigeyuki Nakaji*, Kazuo Sugawara* and Takashi Kumae *Department of’ Hygiene, Hirosaki University School of Medicine. Hirosaki; .-Shiroto Clinic Coshogawara, Aomori: Department of Industrial Health. The Institute of Public Health, Tokyo. Japan. There have been many reports on the applications of low reactive level laser (LLL) therapy for pain attenuation or pain removal. Our group has reported previously on the effects of in vitro irradiation of LLLT particularly on the phagocytic activity of human Neutrophils, using luminol-dependent chemiluminescence (LmCL) for measurement of reactive oxygen species

Pain scores and side effects in response to low-level laser therapy (LLLT)/ Cold Laser Therapy for physical trigger points

E Liisa Laakso Carolyn Richardson, and Tess Cramond 1: Physiotherapy Department, Royal Brisbane Hospital, Brisbane; 2: Physiotherapy Department, University of Queensland, Brisbane; and 3: Pain Clinic, Royal Brisbane Hospital, Brisbane, Queensland, Australia. Clinically, Low Level Laser Therapy – LLLT has been used successfully in the treatment of chronic pain but many have questioned the scientific basis for its use. Many studies have been poorly designed or poorly controlled. A double-blind, placebo-controlled, random allocation study was

Physiological responses in chronic pain patients LLLT protocol

Scott D. Fender and David Diffee. Pain Research Group, Arvada, Colorado, U.S.A. Use of Low Reactive Level Laser Therapy (LLLT) utilizing helium-neon lasers has increased lately especially in pain control. New protocols are being developed aimed at a complex of primary and secondary symptomologies. One of these protocols, Stellate Ganglion Stimulation, has shown in our research a unique set of developments. Targeting the area of the stellate ganglion is showing great promise in the rehabilitation of
