The arms are pivotally connected at their inner ends. An actuator is connected to the arms for applying force to the arms to pivot them relative to each other to move the joint. The actuator includes flexible force transmitting means connected with at least one of the arms, and drive means for applying force to the flexible force transmitting means to move the first and second arms relative to each other. In a preferred embodiments, the flexible force transmitting means is a rope or cable and the drive means is a manually actuatable winch for winding the rope or cable. The drive means is located at a distance from the pivotal connection of the first and second arms. The orthosis is adjustable while on the limb to a plurality of different positions including at least a first position in which the joint is flexed to a relatively greater degree and a second position in which the joint is extended to a relatively greater degree. The orthosis can also be used to flex.
