Description

  The present invention relates to a walking assistance device worn by a rheumatic patient on a foot after surgery.

  Currently, for patients with severe rheumatism such as valgus flat feet, surgery (such as the Swanson-Clayton procedure) is performed to insert a wire into the toes. As shown in Non-Patent Document 1, after this operation is performed, the patient's footpad has a wire protruding from the tip. Although there is a supporter for fixing the affected area after surgery, it is painful if the patient tries to walk with his weight on the foot in this state, so it is difficult to walk normally as it is until the extraction nail for extracting the wire Become.

  Conventionally, patients often wear a cast covering the entire foot for a period of about 3 weeks from the operation to the extraction nail, and during that time it is necessary to walk with a heel or use a wheelchair. It was. However, since normal walking is not possible, the leg muscles are weakened and thinned, and it is difficult to remove the cast and start normal walking again.

  On the other hand, patients with rheumatism can tailor shoes and insole (plantar plate) according to their symptoms. Although foot pain during walking is reduced by using such customized shoes and plantar plates, these do not correspond to the state of the footpad after surgery as described above, It cannot be said that the difficulty is solved.

  Patent Document 1 discloses a shoe for a person with a disorder such as rheumatism in a foot. However, this was also devised to reduce foot pain during walking and to solve problems in appearance for people with rheumatism, and it was not intended for patients with rheumatism after surgery. This is unsuitable for rheumatic patients to use for post-operative walking.

By preventing the affected part from entering the field of view, an effect of relieving psychological distress can be expected.

  The sole plate can be composed of, for example, a core material, an elastic member, and an insertion member that fills a gap between the core material and the bottom plate of the main body. The core material is made of a plastic material according to the shape of the patient's sole so as to be in close contact with the sole when worn. Thereby, coupled with the fixing device, the walking assistance device is more securely fixed to the foot. The interposing member prevents a deflection of the core material when weight is applied by filling a gap between the core material and the bottom plate of the main body.

  It is desirable to provide an appropriate elastic member on the surface of the core material in accordance with the part of the sole. For example, a rubber-based elastic member can be used near the metatarsal head, and an acrylic elastic member having a higher cushioning property can be used at the metatarsal distal end. With this configuration, the rubber-based elastic member attached in the direction of the toes prevents slipping of the foot in the orthosis during walking, and the acrylic elastic member evenly applies pressure on the user's foot. Can be dispersed. Further, if an acrylic elastic member having a large number of holes is used, the adhesion to the foot can be improved and the steaming of the foot can be suppressed.

  The sole plate can be configured to be detachably attached to the main body using a hook-and-loop fastener or the like. With such a configuration, the wire can be removed from the main body after being pulled out and reused as an insole for own shoes.
