Abstract
In this technical report, we present for the first time a newly developed multimodal light-emitting diode (LED) pad for photobiomodulation (PBM). In order to demonstrate the range of possibilities for its application, we carried out a comparison of measurements with and without infrared (IR) LEDs in a volunteer, and are presenting the results. The pad consists of several components, which are mainly composed of LEDs of different modalities (IR, red, yellow, and blue). This multicolor system was applied to a peripheral area of the body in the volunteer. Thermal imaging of the region of interest showed that additional stimulation with IR LEDs increased temperature by about 113% compared to stimulation without IR LEDs. Our results concluded that non-visible IR LED stimulation techniques could be extremely helpful in improving the quality of PBM.
