The Effect of Photobiomodulation on Microvascular Blood Flow: The Role of Wavelength and Skin Temperature
Sponsor: Afeka, The Tel-Aviv Academic College of Engineering
Summary
The objective of this study is to assess peripheral microcirculatory hemodynamic responses to photobiomodulation in participants with normal circulation and with functional peripheral vasoconstriction, using noninvasive thermography, photoplethysmography, and laser Doppler flowmetry.
Official title: Evaluation of Hemodynamic Changes in Peripheral Microcirculation in Response to Photobiomodulation Using Non-Invasive Optical and Thermal Technologies
