摘要: We compared the analgesic effects of continuous and frequency-modulated red infrared LEDproduced polarized light (PL) measured in a formalin test model. The control group consisted 20 albino mice, while six experimental groups included 10 animals each. Red LED PL (637 nm) was found to be more effective suppressing pain than (860 nm); when applied locus pain, average normalized intensity analgesia 43.6 12.9%, on average, respectively. This difference not due dissimilarity radiation power density (26.5 25.4 mW/cm2) but rather unequal wavelength ranges. also studied applications (with no component) modulated at frequencies 10, 600, 3000, or 8000 Hz. In all series where used, weaker case (43.6%). A relatively greater effect (35.2%) recorded modulation frequency 600 Hz, smallest (25.0%) observed
