Abstract: Dynamic orthosis for drop foot, with a vertical flat, rigid bar connected to a collar of a patient's leg, and whose lower free end is connected to a bearing which is positioned in front of the internal malleoulus of the user and to constitute the joint of a cantilevered arm whose free end is connected to a bracket for the foot, and whose motion required for lifting the foot during deambulation is obtained by the force generated by a magnetic spring with the interposition of a rod, wherein the required lifting force are produced by a plurality of magnets, vertically aligned in a cylindrical sheath, and with the same polarity being juxtaposed to allow using their mutual repulsive forces.

Abstract: Dynamic orthosis for drop foot, with a vertical flat, rigid bar (1) solid to a collar (2) of a patient's leg (3), and whose lower free end is solid do a bearing (4) which is to take position in front of the internal malleoulus (30) of the user and to constitute the joint of a cantilevered arm (5) whose free end is solid to a bracket (8) for the foot, and whose motion required for lifting the foot during the deambulation is obtained by the force Fs generated by a magnetic spring (9) with the interposition of a rod (94); the required lifting force Fs being produced by more pairs of magnets (92) vertically lined up and with the same polarity being juxtaposed to allow using their mutual repulsive force. The loading phase of the spring (9) corresponds to the pressure of the foot onto the ground and, therefore, to the maximum moment onto the malleoulus exerted by the compression of the magnets upon the movement thereof close to each other.

Abstract: The tutor of this invention is made up of a support (1) to be fixed to the chest of the user with a chin rest (2) being connected to the support (1) through a hinge (7) and also being anchored at an element (3) provided on the patient's neck, and of a plate (4) positioned on the convexity of the patient's dorsal curve and having applied thereto a posteroanterior thrust. The said chin rest (2) is engaged to a means (8) articulated to the support element (1) in a central position with respect to the chin rest (2) and is able to generate and adjust an anteroposterior upwardly oblique thrust F on the chin of the user.
