The effectiveness of this technique lies in the use of heat as well as alternating temperature.  As R.M.T.'s we know one of the main functions of massage is to increase circulation in tight tissues.  Massage dilates the blood vessels flushing the tight area with fresh blood flow. Now imagine doing that WHILE holding a hot stone.  The use of heat really speeds blood flow into the tissue, much quicker than our hands alone can accomplish. When the R.M.T. encounters an area that is particularly tight, we can choose to alternate between hot and cold stones to dilate and constrict the vessels.  This acts like a pump bringing in fresh oxygenated blood, mobilizating waste products that were trapped, and then pushing it all back out of the tissue when the constricting cold stone is introduced. We can alternate between hot and cold stones several times if needed. We can choose to end on a hot stone (great for regular muscle tightness) or end on a cold stone ( excellent to control inflammation).  In the matter of a minute or two the tissue just softens and melts under your hands! You will find it surprisingly easy to feel the tissue tension right through the stone. You can use stones for your entire treatment or just the beginning of the treatment allowing them to do most of the hard work for you and therefore saving your hands!
