Aside from the usual punches and kicks found in most modern karate styles, traditional Okinawan karate contains an advanced form of grappling known as tuite-jitsu. This art synthesizes a combination of chin na and Okinawa’s native wrestling art known as tegumi, and focuses on techniques of joint manipulation, pressure points, strangle holds or chokes, hyper extensions, throws, and breaks that are hidden within the movements and principles of kata, to control one’s opponent. An understanding of tuite-jitsu can only come through the study of body mechanics and human anatomy, but when these principles and concepts are grasped, it opens an infinite number of both techniques and escapes. The techniques are practiced individually at first, to provide an understanding of each individually, and then built into "flows" to mimic a more real-world application so that the practitioner develops a feel for his opponent's reactions and can flow seamlessly from one technique to the next.
