The device has a support (1) for positioning and locking the forearm of a child. A gripping ball (6) is secured to the support at a front edge of an upper surface of the support, where the gripping ball is movable in rotation about two axes relative to the support. A transverse axis is coincident with the edge and is parallel to another transverse axis (Y) when the device is in a neutral position. An axis located in a vertical plane (XZ) is perpendicular to the upper surface of the support. |
