If you control the head (of the opponent), you control the whole body: in the wrestlers’ world, this saying is well known and for a reason. Even if they are confronting a trained opponent with well-developed neck muscles, thai boxers are highly skilled in applying Muay Thai’s trademark neck hold, Chap Ko: by locking one or two hands around the opponent’s back of the neck every Nak Muay is accomplished at controlling and consequently manipulating his foe’s entire body with great ease. Such total control enables to unleash savage strikes on all sensitive targets. Additionally, if it is true that the neck muscles can resist well to lateral or frontal rotations, a sharp diagonal twist that turns the backbone simultaneously over two axes, can easily cause a cervical vertebrae’s fracture.
