Abstract: The orthosis joint is for orthoses for two parts of the body which can be bent and stretched against each other, such as knee or arm orthoses. The orthosis joint rotationally connects two splints that are each connected to upper and lower parts of the orthosis that can be fastened to the respective part of the body and comprises a pair of splints with orthosis joints that are arranged laterally and/or centrally, respectively, on the orthosis, and the splints mesh with each other at their ends by way of one or several common pins or by teeth are provided at the ends in the orthosis joint and adjustable end stops are provided for extension and/or flexion. The end stops are adjustable over one or several angular ranges &dgr; and that flexion or extension, respectively, in the orthosis joint undergoes constant or dynamic braking within an angular range of &dgr;+&agr; or &dgr;−&agr;, &agr; representing an angle from 3 to 25°.
