The Knee ProWrap delivers three in one care to your injury. First, there's the supportive wrap made from breathable neoprene, so it's comfortable to wear either over or under your clothes. Next, there's the FAR infrared heat pad, held securely in place by the ergonomically designed support. This enables you to apply healing heat therapy, safely and comfortably. The heat penetrates deep into the tissues for comprehensive pain relief. It also makes it easier to move the joint. Many people that wearing a heat pad helps them do their prescribed exercise more easily. The handheld control allows you to control the heat and, with a thirty-minute safety cut off, there's no danger of burns. The third element of the Knee ProWrap is its horseshoe-shaped cold pack insert. Very often physicians advise the use of both hot and cold therapy. This insert can be kept in the freezer for use on acute pain and inflammation or as directed by your health professional. This reliable, effective and reusable method of pain reliever is a top best seller.
