Flat feet correction aid {AUXILIARY CORRECTION DEVICE FOR FLATFOOT}

The present invention relates to an auxiliary device for correcting flat feet, and more particularly, to an auxiliary device for correcting flat feet, which enables the arch of the foot to be raised by preventing excessive pronation of the foot by allowing only toes to be moved while the heel is fixed.

Flat feet is an abnormal alignment in which the arch of the foot is reduced due to excessive pronation of the foot. and is also called a flat foot.

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 be accompanied by 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 in the lower extremities by changing not only foot-related diseases such as plantar fasciitis and hallux valgus, but also proximal (knee, hip, etc.) lower extremity biomechanics.

Until now, most rehabilitation equipment for flat feet has focused on the passive support structure of bones or ligaments, and attention has been paid to temporary intervention methods such as foot orthoses, insoles, and taping. It is known to contribute to alleviating flat feet by providing However, the imbalance caused by the contraction of the extrinsic and intrinsic muscles of the foot is rather undesirable for people with flat feet.

In this regard, in the 'anterior and posterior tibial relation and toe force strengthening device (JP6802557 B2)', the anterior and posterior tibial relation and toe force having a heel loading plate for loading the heel and a leg loading plate provided in front of the heel loading plate In the strengthening device, a device is disclosed in which the leg mounting plate is installed on the sliding member in the front and rear directions, and the front end of the leg mounting plate is installed on the rocking member in the vertical direction.

However, there is no separate means for fixing the heel on the heel loading plate, so even if the toe is moved forward and backward by seating the boundary between the tarsal area and the metatarsal area around the foot, it eventually induces slippage of the foot and stabilizes flat feet. is difficult to correct.

Therefore, there is a need for a new assistive device that enables flatfoot rehabilitation training by raising the arch of the foot while preventing excessive pronation of the foot by allowing only the toes to be moved while the heel is fixed.
