Thai massage uses gentle pressure and stretching techniques to relax the whole body. This is an ancient healing practice that originated in India. ... Unlike Swedish or shiatsu massage techniques, in which a person passively lies on a bed, the client lies on the floor and participates more actively in the massage. One could be forgiven for thinking that the practitioner and patient are wrestling during a Thai massage session. The Thai technique is one of the full-body massage programs built-in to the Osaki OS-4000T massage chair.
