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.

Conditions

  • Microcirculation

Interventions

DEVICE

Photobiomodulation - Blue Wavelength

Photobiomodulation delivered at a blue wavelength (400-500 nm) to the hands during a single study session as part of a randomized crossover design.

DEVICE

Photobiomodulation - Near Infrared

Photobiomodulation delivered at a near-infrared wavelength (780-1100 nm) to the hands during a single study session as part of a randomized crossover design.
