Description

AUXILIARY CORRECTION DEVICE FOR FLATFOOT

The present invention relates to an assistive device for correcting flat feet, and more particularly, to an assistive device for correcting flat feet that allows only the toes to move while the heel is fixed, thereby preventing excessive pronation of the foot and increasing the arch of the foot.

Flatfoot is an abnormality in which the arch of the foot is reduced due to excessive pronation (excessive pronation) of the foot. and is also called flatfoot.

Normally, the load of the human body on the ground is finally distributed from the sole of the foot through the foot to minimize the force applied to the human body. If endurance occurs continuously, pain occurs in the ankle, and in severe cases, pain may accompany pain in other parts of the body other than the ankle, such as knee pain.

As such, flat feet are a major cause of musculoskeletal disorders of the lower extremities by changing not only foot-related diseases such as plantar fasciitis and hallux valgus, but also the proximal (knee, hip, etc.) lower extremity biomechanics.

Until now, most of the rehabilitation equipment related to flat feet has focused on the passive support structure of bones or ligaments and has drawn interest in temporary intervention methods such as foot orthosis, insole, and taping. It is known to contribute to the relief of flat feet by providing However, the imbalance caused by the contraction of the extrinsic and intrinsic muscles of the foot is rather undesirable for those with flat feet.

In relation to this, in 'Anterior and posterior tibial relationship and toe force strengthening device (JP6802557 B2)', an anterior and posterior tibialis relation and toe force with a heel loading plate for loading the heel and a leg loading plate provided in front of the heel loading plate In the reinforcing device, there has been disclosed a device in which the leg mounting plate is installed on a slide material in the front-back direction, and the front end of the leg mounting plate is installed on the rocking material in the vertical direction.

However, since there is no separate means for fixing the heel on the heel loading plate, the boundary between the phalanges and metatarsals is seated centered on the grip part, and even if the toes are moved forward and backward, it eventually causes the foot to slip and stabilizes the flat foot. is difficult to correct.

Therefore, there is a need for a new assistive device that allows only the toes to move in a state where the heel is fixed to prevent excessive pronation of the foot while raising the arch of the foot to enable flat foot rehabilitation training.
