Laser Therapy For Animals

Laser biostimulation involves applying a laser beam to the tissue to facilitate healing and regenerative processes. Laser therapy is one of the most important physical methods used in human physiotherapy. In veterinary medicine, laser therapy is a new and so far poorly examined method. The results of studies conducted so far are very promising

The positive effect of laser therapy on the organism observed in clinical trials gave rise to more detailed study of cells and tissue exposed to laser radiation. In vitro studies on broblasts and endothelial cells isolated from the skin and aorta of C3H mice irradiated with red and infrared laser light have shown that the higher the wavelength of the red light, the more eective is the growth of broblasts. The optimal length for the endothelial cells was 655 nm, and the wavelength of 810 nm inhibited growth of both endothelial cells and broblasts (Moore et al. 2005). Another study evaluated in vitro the eect of laser radiation on the acethylcholinesterase (AChE) activity in erythrocyte membranes. The red cells were exposed to laser radiation at a wavelength of 808 nm and 905 nm with variable parameters. Authors indicated that the laser biostimulation caused changes in AChE activity depending on the parameters used. The highest increase of AChE activity was obtained using laser light with the wavelength of 905 nm and 1,000 Hz or 2,000 Hz with the peak pulse power of 1,100 mW and energy dose of 3J (Past ern ak 2012). Renno et al. (2011) demonstrated a positive eect of laser radiation with a wavelength of 660 nm on the granulation and epidermisation of second-degree burn wounds in rats. Similar results were obtained by Voronkov et al. (2014), who exposed the surface of burn wounds in rabbits to red and near-infrared laser radiation and observed a signicantly reduced inltration of tissue with leukocytes, reduced swelling of the dermis and much more numerous and more organized collagen bres than in the control group. Also K ová cs (2015) in her studies observed a positive inuence on deep, extended wound healing after LLLT treatment with a wavelength of 810 nm in 5 dogs. Laser radiation with wavelengths of 600 nm and 684 nm at 7.5 J/cm2 of carrageenan-induced rat paw oedema eectively reduced the formation and size of the oedema and migration of inammatory cells (Alb ert ini et al. 2007). Laser photobiostimulation with a wavelength of 830 nm at 4 J/cm2 of damaged tibialis anterior muscles in rabbits eectively reduced inammation in the injured tissue, and signicantly increased the level of myogenin in the treatment group compared to the control group (Pertille et al. 2012). Similar results were obtained by Rodrigues et al. (2013), who exposed damaged tibialis anterior muscles in rats with a wavelength of 660 nm at 10 J/cm2 and 50 J/cm2. Both Albe rti ni et al. (2007) and Rodri gue s et al. (2014) demonstrated that LLLT reduces immunoexpression of COX-2 in damaged muscles, thus decreasing the severity of inammation and facilitating tissue repair processes. Tests were performed on the safety of high-intensity laser therapy in which 8 cm2 of the back of mice were irradiated twice a week for six months. Two wavelengths, 585 nm and 1320 nm, were used at various energy doses ranging from 8 to 20 J/cm2. Both during and after the test, there were no deaths, symptoms of intoxication, or neoplastic processes in any of the mice (Chan et al. 2007).Human medicineIn human medicine, the biological eects of low-level laser therapy began to be investigated in the mid-1960s. As early as 1969, Dr. Endre Mester successfully used laser light to treat non-healing skin ulcers, and thus introduced lasers to medicine (M est er et al. 1985). Low-level laser therapy has found application in the treatment of hard-to-heal wounds and skin injuries (especially decubitus ulcers), chronic and subacute inammation of soft tissue, oedema, calcaneal spurs and the carpal tunnel syndrome (Bau er et al. 2012).
