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 […]

Low Level Laser Therapy (LLLT) for wound healing is effective in modulating both local and systemic response. 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 […]

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.

The peripheral nervous system is photosensitive, the scientific rationale for this study which determines the efficacy and safety to laser light exposure in 30 cases with CTS. Nine joules of energy over 5 points (7-15 treatments) reversed CTS in 77% of cases with three-fold normalization of CMAP. A photobiologic response was seen in 80%. This unique and novel approach is cost-effective and has a role in future management of CTS.
