Remote effects of electromagnetic millimeter waves on experimentally induced cold pain — A crossover double-blinded investigation in healthy volunteers

The hypoalgesic effect of millimeter waves (MW) was studied using experimental pain model of Cold Pressor Test (CPT) in healthy volunteers. Skin of the lower part of sternum of each volunteer was exposed to either source of MW with 42.25 GHz ("fixed frequency" generator), 50-75 GHz ("noise frequency" generator) or inactive device ("placebo" generator) in a random order. Pain threshold, pain tolerance and diastolic blood pressure within CPT increased under the exposure to "frequency generator" as compared to baseline and to "noise" generator, but not vs. placebo.
