The purpose of the utility model: The purpose of the device is to increase the efficiency of the recovery of the ankle joint function by simplifying the design of the device: reducing the number of components and assemblies, increasing the reliability of the seat lock, and provide direct force transmission from the engine to the lower limbs by using a helical gear.The device for the treatment of stiffness in the ankle joint consists of a frame with holes. With the frame is connected to the seat frame by sliding the sliding frame and the frame. Sliding frame has openings. With sliding frame is connected through a chain stopper. On the seat frame fixed seat backrest and headrest. With the frame is connected to L-shaped frame. Within the L-shaped frame is threaded rod is movable. The threaded rod is connected to the frame by a bolt and a bolt the bolt. For threaded rod attached handle. Within the L-shaped frame is placed a threaded rod slidably. The threaded rod is connected to the frame by a bolt and a bolt. On a threaded rod attached handle. On the L-shaped frame fixed to the engine in case I gearhead housing. With the gear in the housing is connected to a rod with a screw thread. A rod with a screw thread secured within the bearing housing. Bearing in the housing is fixed to the L-shaped frame. On the rod with screw thread worn slider. With the slider rod is coupled by a hinge. The rod is connected by a hinge with podstopnikom. Podstopnik connected to the T-frame by a hinge. On podstopnike belt fastened with tape, "Velcro." With the motor in the housing connected in series network switch, the switch turns of wire and the plug means.The technical result of the proposed utility model:- metered controlled increase range of motion in the ankle joint with no axial load. The design provides a comfortable position of the patient (reclined) in the device. The design does not contain elements that create resistance and forcing the patient to strengthen the load on the ankle
