Abstract
An assembly for a body joint orthotic that generates a distraction force to the joint that can be synchronized with the flexion of said joint. The hinge may be polycentric or unicentric. For a polycentric hinge, the distraction can be generated by varying the distance between the axes of rotation of the two pivot points. For a unicentric hinge, the distraction can be generated by increasing the length of at least one of the arms that connects the strapping element which holds the orthotic to the limb or body part to the hinge. The synchronization of the amount of distraction to the angle of flexion may be achieved by purely mechanical mechanisms or involving a motor.
