BioWaveGO replacement pain relief pads are for use with the BioWaveGO device for pain relief neurostimulation therapy. they utilize a nonallergenic, pre-applied, conductive hydrogel which is applied on the skin directly over the pain site. BioWaveGO pain relief pad placements are different from conventional electrical stimulation. The active electrical field forms beneath the skin surface and surrounding each pain relief pad. BioWave's therapeutic electrical signals go through the skin into deep tissue right to the surface of pain fibers and block pain signals at the source from traveling up to the brain.
