The method for producing an orthotic brace is comprised of the following steps:1. Generation of a 3D image/scan of the injured area.2. Preparation of a virtual 3D model of the limb.3. Determination of the use conditions for the orthosis.4. Preparation of a virtual 3D model of the orthosis and adjustment of the model.5. 3D printing of the elements of the orthosis frame core (2).6. Preparation of the composite cover of the frame (1), preferably together with at least one electrostimulation circuit (4).7. Comparison of the printed elements of the orthosis with the orthosis hinges (5), external elements (6) of the frame (1) and elements of the electrostimulation system.and the orthotic brace according to the invention, containing a rigid frame (1) with a four-point limb and joint stabilisation system, a polycentric hinge (5), whose composite frame (1) is provided with an electrostimulation circuit (4) with at least two electrodes (7).
