Definitions

  • the invention relates to an orthosis for supporting a leg of a user during walking, comprising a trunk engaging part, a foot engaging part and a first connecting part, the trunk engaging part being designed for engaging a trunk of the user and the foot engaging part being designed for engaging a foot of the leg of the user, the first connecting part extending between of the trunk engaging part and the foot engaging part, the first connecting part being flexible, and the first connecting part comprising a first elastic part which, in use, is biased to an extent such that the trunk engaging part and the foot engaging part are drawn towards each other.
  • Such an orthosis can, for instance, be used as an aid by people suffering from one-sided paralysis, which aid enables them to walk without other orthopaedic aids such as, for instance but not exclusively, special footwear, crutches or walkers.
  • Japanese patent publication JP 2004337561 discloses an orthosis for assisting in lifting of both lower legs of a user, for instance of an elderly person, by means of two elastic bands, each extending from a shoulder or hip, along the front side of the corresponding leg, passing under the corresponding foot, back to the respective shoulder or hip.
  • This orthosis has the advantage that it can be designed to be lightweight, so that a user needs not carry along a heavy orthosis.
  • this known orthosis has the drawback that this orthosis applies substantially only one force to the lower leg, directed upwards relative to the user, but increases the stability of the leg to an insufficient extent. As a result, this orthosis is less suitable for users with reduced stability in one leg, for instance people suffering from one-sided paralysis. That is why, for this group of users, the mobility is still limited.
  • the object of the invention is to reduce the above-mentioned limitation of the mobility for a user and/or increase the stability of the leg of the user.
  • the orthosis according to the invention is characterized in that the orthosis is designed such that, in use, the first connecting part extends in a longitudinal direction of the leg in the direction from the foot engaging part to the trunk engaging part, at least for a part along a front side of the lower leg and, thereupon, extends at least for a part along a rear side of the upper leg.
  • the first elastic part offers the advantage that, in use, the leg is lifted, at least partly, through elasticity of the first elastic part, which reduces the effort of the user.
  • the orthosis according to the invention can be used, for instance, by users having a reduced tension in the quadriceps/hamstrings, as a result of, for instance, a stroke /apoplexy (cerebrovascular accident CVA), congenital brain damage, brain damage resulting from an accident, lingering effect after brain tumour (surgery), multiple sclerosis (MS) and/or polio.
  • a stroke /apoplexy cerebrovascular accident CVA
  • congenital brain damage congenital brain damage
  • brain damage resulting from an accident lingering effect after brain tumour (surgery)
  • MS multiple sclerosis
  • polio polio
  • the first connecting part is connected, in use, to the foot engaging part at a location on the foot engaging part situated anteriorly to an ankle of the user.
  • the foot engaging part is pulled in the direction of the trunk engaging part through the bias of the first elastic part.
  • the orthosis maintains the foot in dorsiflexion, which simplifies walking further.
  • an amplitude of a circumducting movement of the leg is reduced, which reduces the effort for the user.
  • This orthosis can be advantageously used by users suffering from, for instance, (optionally in addition to the reduced tension in the quadriceps/hamstrings) a foot levator paralysis (dropfoot).
  • the first elastic part extends in a longitudinal direction of the first connecting part for applying, in use, a tensile force in the longitudinal direction of the connecting part. This offers the advantage that the elastic part can be included in a simple manner in the flexible first connecting part.
  • the first connection part extends, in use, along the front side of the knee, the first connecting part extending adjacent the knee, preferably above the knee, from the front side of the leg to the rear side of the leg, while the first connecting part is split, at least partly, in the direction from the trunk engaging part to the foot engaging part, into a medial part and a lateral part extending along a medial side and a lateral side of the leg, respectively, from the front side of the leg to the rear side of the leg.
  • the first connecting part extends substantially in a longitudinal direction of the leg along a front side of, at least a part of, the lower leg and a rear side of, at least a part of, the upper leg, whereby the first connecting part is substantially prevented from causing a medial or lateral rotation of the leg.
  • the first elastic part extends, in use, along the front side of the knee. This offers the advantage that, in a simple manner, the first elastic part provides a force for stabilizing the leg.
  • the first elastic part extends above as well as below the knee. This offers the advantage that the first elastic part can draw the trunk engaging part and the foot engaging part towards each other in a simple manner. The fact is that even if, when, for instance the knee is bent, the first connecting part experiences friction with respect to the knee, the first elastic part can draw the foot engaging part as well as the trunk engaging part towards the knee.
  • the orthosis is further provided with a second connecting part which extends, in use, in the longitudinal direction of the leg in the direction from the foot engaging part to the trunk engaging part, while the second connecting part is flexible and comprises a second elastic part which, in use, is biased to such an extent that the trunk engaging part and the foot engaging part are drawn towards each other, with the second connecting part extending along a front side of, at least a part of, the leg.
  • the second connecting part provides an additional contribution to lifting the leg and/or maintaining the foot in dorsiflexion, which improves the ease of walking.
  • the second connecting part is connected, in use, to the trunk engaging part at a location on the trunk engaging part situated on a ventral side of the user
  • the first connecting part is connected, in use, to the trunk engaging part at a location on the trunk engaging part located on a dorsal side of the user.
  • the orthosis preferably forms an assembly of elastic and flexible, non-elastic bandages and connecting means.
  • the flexible connecting means of the orthosis support the walking movement of the paralyzed leg while maintaining the (natural) articulating action of the ankle joint, the knee joint and the hip joint, so that one can walk, sit down and even kneel without additional aids.
  • the flexible connecting means of the orthosis can be designed to be relatively flat, the orthosis can furthermore be worn practically invisibly under normal clothing when leg covering clothing such as pants, a long dress or long skirt form part of the clothing,

Abstract

L'invention concerne une orthose conçue pour soutenir la jambe d'un utilisateur pendant la marche, comprenant une partie venant sur le tronc, une partie venant sur le pied et une première partie de liaison, la partie venant sur le tronc étant conçue pour venir en contact avec le tronc d'un utilisateur, la partie venant sur le pied étant conçue pour être en contact avec le pied de l'utilisateur et la première partie de liaison s'étendant entre la partie venant sur le tronc et la partie venant sur le pied. La première partie de liaison est au moins partiellement souple et comprend une première partie élastique qui, lorsqu'elle est utilisée, est sollicitée de sorte que la partie venant sur le tronc et la partie venant sur le pied soient tirées l'une vers l'autre. Ladite orthose est conçue de sorte que lorsqu'elle est utilisée, la première partie de liaison, dans le sens longitudinal de la jambe dans le sens de la partie venant sur le tronc, elle s'étende au moins pour partie le long d'un côté avant de la jambe inférieure et, s'étende ainsi au moins pour partie le long d'un côté arrière de la jambe inférieure.
