Aside from Reiki, there are many other therapies, both ancient and modern, that are based on “touch” and/or “life force.” Each has its own unique history, purpose, and methodology. Techniques used in Healing Touch and Quantum-Touch are very closely related to Reiki. Hands-on healing modalities that are based on the use of ki energies, such as the Alexander Technique and shiatsu massage, involve manipulation of the body's bone structure, muscles, and skin.
