Thermal effects and induced photomechanical effects
Photomechanical Effects and Laser Therapy
Photomechanical effects are changes in the shape of a substance due to exposure to light. The most common mechanism for this is light-induced heating.
The therapeutic effects of heat were known even in ancient times. Accordingly, modern researchers are interested in the therapeutic use of lasers. One modality for High Intensity Laser Therapy (HILT) that they’ve studied is Hilterapia®.
Photomechanical Effects and Hilterapia®: The Research
Recent research on Hilterapia® looked at how to make the best use of the characteristics of a high-peak-power pulsed Nd:YAG laser. The results pointed to specific biological effects that produce important therapeutic target achievement, even in the deepest tissues.
As a result of the characteristics of the high peak power pulsed Nd:YAG laser, the photothermal and indirect photomechanical processes it generates at a cellular level take on a particular importance, These processes appear to lie at the base of effects on the synthesis of extracellular matrix molecules, endothelial cells layer organization, and cell ripening in specialized connective tissues. These photomechanical processes are fundamentally important for tissue recovery.
In other words, thanks to its impulse typology, Hilterapia® has the advantage of transferring heat to precise tissue sections in a very short time even if they have a very small volume and are deeply located.
