Spherical joint mobilization brace

A device (1) for articular rehabilitation comprising a first element (2) provided with bars (24, 25) for fastening to a proximal portion of a limb and a second element (3) provided with bars (34, 35) for fastening to a distal portion of the limb, said first element (2) comprising a first (21) and a second spherical shell portion (22) opposite to each other, and said second element (3) comprising a first (31) and a second spherical shell portion (32) opposite to each other, said spherical shell portions (21, 22, 31, 32) being configured to fasten said first and second elements by means of a spherical hinge coupling so that only relative movements obtainable by means of a composition of rotations around-three axes passing through a center of said shell portions are allowed between said first (2) and second element (3) and being configured so that the space comprised inside said spherical shell portions (21, 22, 31, 32), when coupled, is such that a joint object of the rehabilitation is allowed to be received therein, said first (21, 31) and second spherical shell portions (22, 32) of each one of the two elements (2, 3) being firmly connected to each other and configured to be positioned on opposite portions of the joint when said device (1) is worn, said first spherical shell portion (21) of said first element (2) being configured to be coupled with said first spherical shell portion (31) of said second element (3), and said second spherical shell portion (22) of said first element (2) being configured to be coupled with said second spherical shell portion (32) of said second element (3);

• and wherein the device (1) further comprises an actuation ferromagnetic core (7) which allows exerting a torque between said first (2) and second element (3), so that a patient is helped to carry out a complete extension of the limb;
• and wherein said actuation ferromagnetic core (7) comprises two motorized wheels (60, 61) integral to said outer spherical shell portion and configured to act on said inner spherical shell portion, positioned on opposite portions with respect to a middle of the device, and configured so that said actuation ferromagnetic core (7) imposes a desired amount of lying on one's stomach or on one's back movement during a flexion-extension movement, by controlling a rotation speed of a respective motor.
