The re-educating device comprises a mechanical orthetic device (2, 3, 4) arranged to constitute an interface with at least one of the lower limbs of the patient and a neuromuscular stimulation device (33) comprising at least one pair of electrodes (37, 38) intended to act on the relevant muscle or muscle group of the said limb of the patient. The orthetic device comprises two orthesis, each including three segments (2, 3, 4) intended to cooperate (11, 13, 12, 14, 15) with respectively the thigh, the leg and the foot of the patient. The first segment is connected firstly at one of its end by a first motorized articulation (6) to an element (10) arranged so as to cooperate with the body of the patient at his heaps and on the other end at its other end by a second motorized articulation (7) to one of the ends of the second segment. The other end of the second segment is connected by a third motorized articulation (8) to the third segment. Each of the articulations (6, 7, 8) is provided with an angular sensor and force and torque sensors, coupled to the device (31) controlling the stimulation device, so as to allow retrocontrol by closed-loop control.

Le dispositif de rééducation comprend un dispositif orthétique mécanique (2, 3, 4) agencé pour constituer une interface avec au moins un des membres inférieurs du patient et un dispositif de stimulation neuromusculaire (33) comportant au moins une paire d'électrodes (37, 38) destinées à agir sur le muscle ou le groupe musculaire concerné dudit membre du patient. Le dispositif orthétique comporte deux orthèses comprenant chacune trois segments (2,3,4) destinés à coopérer (11, 13, 12, 14, 15) avec respectivement la cuisse, la jambe et le pied du patient. Le premier segment est relié d'une part à l'une de ses extrémités par une première articulation motorisée (6) à un élément (10) agencé pour coopérer avec le corps du patient au niveau de ses hanches et d'autre part à son autre extrémité par une deuxième articulation motorisée (7) à l'une des extrémités du second segment. L'autre extrémité du second segment est reliée par une troisième articulation motorisée (8) au troisième segment. Chacune des articulations (6, 7, 8) est munie d'un capteur angulaire et de capteurs de force et de couple, couplés au dispositif de commande (31) du dispositif de stimulation de façon à permettre un rétrocontrôle par réglage en boucle fermée.
