Laser light & Biostimulation
Biostimulation is the ability to stimulate and promote tissue growth and repair at the cellular level.
The wavelengths of laser light are mainly absorbed by the chromophores, molecules located inside cells able to convert laser light. The products of this process are indispensable substances for the repair, growth and proliferation of cells.
Using the appropriate wavelength, the maximum therapeutic effect on the target tissue can be achieved.
Depending on the modulation of the wavelength and on the different parameters set, different effects can be achieved:
Laser light is absorbed and partly scattered in the target tissue and thereby largely converted into heat.
This thermal stimulus to the nociceptors of the skin affects the peripheral neurological tract and polarizes the neurons important for our pain perception.
This polarization activates the neural and humoral endorphinergic pain inhibition system with immediate pain relief as a result.
Inflammation is necessary for healing. The challenge for the clinician is to control this acute inflammatory stage in order to allow the next stage of healing. The HPL units effectively modulate the inflammatory processes secondary to their deep stimulation of tissues. This deep stimulation triggers vasodilatation and increased oxygenation, which activates the main metabolic activities and resolves the inflammatory process quicker.
The described acceleration of healing processes primarily manifests in the form of fibroblast activation. The actual cascade of healing is fueled by increased ATP synthesis and increased protein synthesis combined with cellular proliferation. Because of the non-thermal nature of this activation, only small amounts of laser energy are required. The attenuation of the laser light in the tissue depends on the localization of the lesion and determines the laser power required. Deeper structures such as tendons or joint capsules may require the application of higher doses to the surface.
