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 […]

A randomized, double-blind study was initiated in 1990 to evaluate an eight-point conservative treatment program in carpal tunnel syndrome. 160 patients were delineated with symptoms of carpal tunnel syndrome and these patients were then divided into two groups. Both groups were subjected to an ergonomically correct eight-point work modification program. A counterfeit LLLT unit was used in Group A, while an actual LLLT unit was used in Group B. Groups A and B were statistically significantly different in terms of return to work, conduction study improvement, and certain range of motion.
How laser light helps cells repair themselves CAN gentle doses of laser light help cells to heal?” THE NEW SCIENTIST, October 11-15, 2003 How laser light helps cells repair themselves CAN gentle doses of laser light help cells to heal? The technique is sometimes used to treat problems such as tinnitus and joint pain, but with no explanation for how these therapies work, there is scepticism over whether the effect is real. Now a physicist has come up with evidence that the physical forces generated by low-energy laser beams may switch on cells’ repair mechanisms. This will support the growing body of evidence that laser therapy is beneficial. At the Joint International Laser Conference in Edinburgh, UK, last month, researchers reported promising results for fields as diverse as IVF and spinal injury. For example, rats with damaged spinal cords made a better recovery if their wound was illuminated with near-infrared laser light, reported Kimberly Byrnes of the Uniformed Services University of Health Sciences in Bethesda, Maryland. Her team found that in light- treated rats, levels of interleukin-6, which is involved in inflammation, were only 1 per cent of the levels in a control group of rats. But Byrnes does […]
