Laser therapy is a method of local exposure to electromagnetic radiation of the optical spectrum, which has coherence, monochromaticity and low output power (from 2 to 50 mW), which is carried out using an emitter located above a certain exposed area of the patient's body at a distance of 10-100 cm or by contact.
All physicochemical and subsequent photobiological reactions during laser therapy are basically similar to those during light therapy.
The features of the factor's action are determined by the properties of low-energy laser radiation (LER). Thus, the monochromaticity of LER allows for its significant spectral density, and for precise regulation of the PPM of a very narrow spectrum of EMR. The coherence of LER significantly increases its intensity in the beam's cross-section (frontal intensity of EMR). This property allows for the initiation of more pronounced (compared to the effect of incoherent, non-monochromatic EMR, i.e., ordinary light) electrodynamic changes in the body's tissues due to the occurrence of a pronounced internal photoelectric effect in biological substrates at a low EMR output power (and, accordingly, a low PPM).
It should be noted that, in accordance with the laws of quantum physics, the impact of pulsed NLI at a frequency above 1000 Hz is perceived by the object (bio-object) as a quasi-continuous impact.
The main clinical effects of laser therapy are: analgesic, anti-inflammatory, anti-edematous, antispasmodic, regenerative, desensitizing, immunocorrective, vasoactive, hypocholesterolemic, vagotonic (with initial sympathicotonia, i.e. with a predominance of the tone of the sympathetic part of the autonomic nervous system), bactericidal and bacteriostatic.
