Abstract: Movement restraining device (1) for partially immobilizing a body joint (10). The device comprises stopper elements (50, 60) having an abutment surface (100) and an abutting surface (70). One stopper element is pivotable, relative to the other stopper element. The device further has skin attachment means (90, 120) for attaching the stopper elements to skin. The abutment surfaces are arranged or shaped such that, in an abutting pivot position, they prevent pivoting in a first pivot direction (150), while allowing pivoting in a second pivot direction (160), opposite to the first pivot direction.
