Simple yet effective self-massager makes it easy to apply pain-relieving deep compression directly to hard, knotted "trigger points" anywhere they occur - breaking up tension even in the hardest-to-reach muscles. Pressure applied to the muscles by the Thera Cane helps to maximize the flow of oxygenated blood to the muscles. This pressure aids in restoring muscle function by breaking up adhesions in muscle fibers and tendons. The increased circulation helps the muscle to work more efficiently.
