TDP is an acronym for "Teding Diancibo Pu" (特定电磁波谱) which loosely translated to “special electromagnetic spectrum." TDP lamp involves the use of a heated mineral plate, consists of a formula of 33 trace elements, that emits far-infrared radiation in the 2–50 micrometer range to increase micro circulation, loosen muscle and ligaments, and accelerate the natural healing processes of the body. We mostly use to release tightness and pain and to speed up recovery. The treatment is comfortable and many patients reports that the heat sensation is very mild and relaxing to the muscles.
