Tui na is an ancient Chinese system of manual therapeutics with a wide range of techniques and indications. While traditional Chinese medical precepts form its theoretical basis, clinical experience governs its application. Tui na techniques range from those that are light and soothing to those that are strong and invigorating. Refined over the centuries, tui na facilitates healing by regulating the circulation of blood and qi (vital energy), which controls body function and enhances resistance to disease. The term tui na (pronounced t-weigh na) combines the names of two of the hand techniques, tui meaning to push and na meaning to lift and squeeze, which are used to represent the system. Practitioners of tui na claim there are more than 365 hand techniques, although they can be generally placed in the category of pressing, rubbing, waving, shaking, percussion, or manipulating.
