Abstract
Description
La présente invention concerne un appareil de rééducation de la cheville. The present invention relates to an ankle rehabilitation device.
Parmi les appareils de rééducation de la cheville, le plus sirnple consiste en un plateau monté sur une demi-boule autorisant, d'une manière non contrôlée par le patient, à la fois les trois mouvements: flexion-extension, pronosupination et rotation. Among the ankle rehabilitation devices, the simplest consists of a plate mounted on a half-ball allowing, in a manner not controlled by the patient, both the three movements: flexion-extension, pronosupination and rotation.
Toutefois, cet appareil ne permet de trouver que très difficilement un équilibre, c'est-à-dire que la plupart du remps un bord du plateau touche le sol.However, this device makes it very difficult to find a balance, that is to say that most of the time an edge of the plate touches the ground.
Or, la recherche de l'équilibre est très importante pour la rééducation musculaire et proprioceptive. En effet, le travail de la cheville autour de cette position a pour résultat de faire travailler tous les muscles et d'exciter tous les réflexes propioceptifs. However, the search for balance is very important for muscle and proprioceptive rehabilitation. Indeed, the work of the ankle around this position results in working all the muscles and stimulating all the propioceptive reflexes.
Un objet de l'invention consiste à prévoir un appareil permettant de faire travailler la cheville autour d ' une position d'équilibre instable, en lui permettant des mouvements d' amplitu- de relativement faible. Un autre objet de l'invention consiste à prévoir un appareil qui respecte le fonctionnement hétérocinétique de la cheville. An object of the invention consists in providing an apparatus making it possible to make the ankle work around an unstable equilibrium position, by allowing it movements of relatively small amplitude. Another object of the invention consists in providing an apparatus which respects the heterokinetic functioning of the ankle.
Un autre objet de l'invention consiste à prévoir un appareil extrêmement simple. Another object of the invention is to provide an extremely simple device.
Suivant une caractéristique de l'invention, il est prévu un appareil se composant d'une planchette repose-pied supportée, du côté interne du pied, sur un plot vertical à base quasi-ponctuelle et, du côté externe du pied, sur le bord inférieur courbe d'un support vertical, le plan dudit bord courbe étant sensiblement parallèle au plan vertical longitudinal du pied, au repos, le plan vertical contenant la trace du plot et le point de contact du bord courbe passant par l'axe de rotation de la cheville. According to a characteristic of the invention, there is provided an apparatus consisting of a supported footrest board, on the internal side of the foot, on a vertical stud with a quasi-point base and, on the external side of the foot, on the edge lower curve of a vertical support, the plane of said curved edge being substantially parallel to the longitudinal vertical plane of the foot, at rest, the vertical plane containing the trace of the stud and the point of contact of the curved edge passing through the axis of rotation of ankle.
Suivant une autre caractéristique, 1 ' appareil est utilisé par paire, c'est-à-dire un pour le pied droit et un pour le pied gauche, les pieds du patient étant posés chacun sur son appareil correspondant. According to another characteristic, the apparatus is used in pairs, that is to say one for the right foot and one for the left foot, the feet of the patient being placed each on his corresponding apparatus.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:
la Fig. 1 est une vue de côté d'un appareil suivant l'invention,
la Fig. 2 est une vue de dessous de l'appareil de la Fig.The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:
Fig. 1 is a side view of an apparatus according to the invention,
Fig. 2 is a bottom view of the apparatus of FIG.
1,
les Figs. 3 et 4 sont respectivement des vues de bout de l'avant et de l'arrière de l'appareil de la Fig. 1, et
la Fig. 5 est une vue en perspective d'une paire d'appareils suivant l'invention, en fonctionnement sous les pieds d'un patient. 1,
Figs. 3 and 4 are respectively end views of the front and rear of the apparatus of FIG. 1, and
Fig. 5 is a perspective view of a pair of devices according to the invention, in operation under the feet of a patient.
L'appareil des Figs. 1 à 4 est destiné à être utilisé sous un pied droit. I1 cornprend une planchette rectangulaire 1 sous laquelle est fixé, en un point A près du bord latéral gauche de la planchette 1, un plot vertical 2 et, à droite le long d'une portion arrière de la planchette 1, un support 3 qui a un bord inférieur 4 courbe relativement mince. L ' appareil est complété par une butée 5 fixée sous le côté transversal arrière de la planchette 1, par exemple près du coin arrière gauche. The apparatus of Figs. 1 to 4 is intended to be used under a right foot. It comprises a rectangular board 1 under which is fixed, at a point A near the left lateral edge of the board 1, a vertical stud 2 and, on the right along a rear portion of the board 1, a support 3 which has a lower edge 4 relatively thin curve. The apparatus is completed by a stop 5 fixed under the rear transverse side of the board 1, for example near the rear left corner.
Quand la planchette 1 est horizontale, comme à la Fig. 1, la droite H-H joignant le point A au point B de contact de la courbe 4 avec le sol passe sous le point 0 de rotation de la cheville et correspond à l'axe de Henke. When the board 1 is horizontal, as in FIG. 1, the line H-H joining point A to point B of contact of curve 4 with the ground passes under point 0 of rotation of the ankle and corresponds to the axis of Henke.
Dans l'exemple décrit, le support 3 est une simple plaque verticale fixée sous le bord droit de la planchette 1 et le plot 2 est fixé sous celle-ci près de son bord gauche, étant entendu que l'appareil des Figs. 1 à 4 est prévu pour supporter le pied droit d'un patient. Un appareil prévu pour supporter un pied gauche serait symétrique de l'appareil des Figs. 1 à 4, par rapport à son axe longitudinal. In the example described, the support 3 is a simple vertical plate fixed under the right edge of the board 1 and the stud 2 is fixed under the latter near its left edge, it being understood that the device of Figs. 1 to 4 is provided to support the right foot of a patient. An apparatus intended to support a left foot would be symmetrical with the apparatus of Figs. 1 to 4, relative to its longitudinal axis.
La butée 5 est prévue pour lirniter l'angle de cabrage de 1' appareil. The stop 5 is provided to limit the tilt angle of the device.
Enfin, on peut prévoir que la hauteur du plot 2 est réglable. De préférence, le bout inférieur du plot 2 est arrondi. Finally, it can be provided that the height of the pad 2 is adjustable. Preferably, the lower end of the pad 2 is rounded.
On peut également prévoir que le longueur du bord 4 de la plaque 3 est réglable. La hauteurs du plot 2 et celle de la plaque 3 peuvent être de l'ordre de cinq centimètres. La planchette 1 peut avoir une forme autre que rectangulaire, mais doit pouvoir soutenir le pied. La forme rectangulaire présente l'avantage de bien définir les orientations.It can also be provided that the length of the edge 4 of the plate 3 is adjustable. The heights of the pad 2 and that of the plate 3 can be of the order of five centimeters. The board 1 may have a shape other than rectangular, but must be able to support the foot. The rectangular shape has the advantage of clearly defining the orientations.
La Fig. 5 montre cornment une paire d'appareils de l'inven- tion peut être utilisée. Chaque pied est posé de manière que le point de rotation de la cheville soit au-dessus de la ligne H-H, qui est, de préférence, tracée sur la planchette 1, avec,l'aligne- ment du second métatarse coïncidant avec l'axe longitudinal X-X de l'appareil. A la pratique, on s'aperçoit que l'équilibre peut être trouvé assez rapidement après quelques essais d'entraîne- ment d'une minute ou deux. Les deux pieds sont donc en équilibre chacun sur l'axe H-H. On notera qu'en utilisation les axes longitudinaux des planchettes ne sont pas nécessairement parallèles, mais divergent vers l'avant. Fig. 5 shows how a pair of devices of the invention can be used. Each foot is placed so that the point of rotation of the ankle is above the line HH, which is preferably traced on the board 1, with the alignment of the second metatarsus coinciding with the axis longitudinal XX of the device. In practice, we realize that balance can be found fairly quickly after a few training attempts of a minute or two. The two feet are therefore in equilibrium each on the H-H axis. Note that in use the longitudinal axes of the boards are not necessarily parallel, but diverge forward.
L'équilibre obtenu est toutefois instable et demande des efforts de contre-réaction continuels. Ce sont ces efforts qui contribuent à rééduquer les muscles de la cheville. The balance obtained is however unstable and requires continuous feedback efforts. It is these efforts that help re-educate the ankle muscles.
On comprend que le rôle de la courbe 4 est de déplacer en avant ou en arrière la ligne joignant le point A et le point courant b de contact de la courbe 4 avec le sol. On a montré à la Fig. 2 les lignes extrêmes A-B' et A-B". En fait le déplacement de cette ligne au cours des mouvements permet de respecter l'hétérocinétique de chaque cheville. We understand that the role of curve 4 is to move forward or backward the line joining point A and the current point b of contact of curve 4 with the ground. We have shown in FIG. 2 the extreme lines A-B 'and A-B ". In fact the displacement of this line during the movements makes it possible to respect the heterokinetics of each ankle.
