Description

Supporting member for flat foot treatment and functional slippers provided with the supporting member

The present invention relates to a support member for treating flatfoot and a functional slipper provided with the support member, and more particularly, to a support member for flatfoot treatment attached to the back of a shoe insole or integrally molded to alleviate discomfort and pain of people with flatfoot It relates to a functional slipper provided with a foot needle member and the supporting member.

In general, there are two types of arches on the sole of the foot of a normal person. Among them, there are the transverse arch, which indicates the arch in the width direction of the foot, and the longitudinal arch, which indicates the arch in the direction of the length (anteroposterior) direction of the foot. In the case of the arch (longitudinal arch), there is a medial corresponding to the medial center of the sole and a lateral corresponding to the outside of the sole (see FIG. 1).

The arch formed on the foot plays an important role in complementing the structure of the sole, which is a narrow support surface, during walking, and is known to play an important role in absorbing the ground repulsion force of 10 times the body weight during walking.

In particular, the case where there is no plantar calf is called flatfoot or flatfoot, and such flatfoot is caused by a complex action between the forefoot, midfoot, and hindfoot of the sole, and refers to a deformation in which the longitudinal arch is reduced or lost. (See Figure 2).

In addition, flexible flatfoot refers to a state in which a normal calf shape is formed on the sole of the foot when the foot is not stepped on, but when the foot touches the floor, the calf arch disappears.

In the case of children, since the feet are flexible and muscles are not developed, most of the calf is not visible when weight is placed on the foot, but as the children grow, the shape of the calf becomes visible as the skeletal structure, muscles, and ligaments of the foot grow. However, according to an academic study (IH Park et al (2004) Flat Foot Survey in 8 Year Old Primary School Children Journal of Korean Foot and Ankle Society, 8(1) , 7-10/ et al.), flatfoot in school-age children The incidence rate is known to range from 12% to 45.5%.

The causes of flatfoot can be divided into pathological flatfoot and physiological flatfoot, in which the development of the medial calf is delayed compared to peers without pathological changes in the skeletal system.

The flatfoot formed in childhood loses its flexibility through adolescence, and the flatfoot is maintained as it is, resulting in plantar pain. When flatfoot continues into adulthood, the possibility of foot deformity increases, causing various pains in the joints of the foot. It is more likely to develop into a disease.

In addition, since flatfoot not only affects the nervous system such as joints, ligaments, muscles, etc., but also causes fatigue or pain in the arch part of the plantar arch when walking, standing for a long time, or walking, orthodontic treatment according to the cause It is of utmost importance to do it on time.

In order to treat such pathological flatfoot, various means for non-surgical treatment (for flexible flatfoot) as well as surgical treatment (in the case of rigid flatfoot) have emerged.

In the case of flexible flatfoot, which accounts for 90% of flatfoot, non-surgical treatment methods include medications, physical therapy, orthodontic shoes, medical insoles, and therapeutic orthosis to relieve symptoms of flatfoot or relieve pain. , it is very rare that such non-surgical treatment is continuously received or continuously performed, and in many cases, it is not easy to use these non-surgical means because of the high economic cost burden.

In addition, there are cases where a medical insole is inserted into the inner sole of the shoe, but an insole suitable for the characteristics of one's feet must be accurately tested through a specialized medical institution, and the insole must be manufactured according to the test result, so there are many ways to use a medical insole. There were difficulties in taking time and economic costs.

The present invention is a treatment for flatfoot that can be easily used in daily life by people with conventional flatfoot to relieve flatfoot symptoms or prevent pathological development by enabling early orthodontic treatment for flatfoot An object of the present invention is to provide a support member and a functional slipper provided with the support member.

In particular, the present invention relates to a support member for flatfoot treatment and this support that can reduce the occurrence and symptoms of flatfoot in school-age with a high prevalence by integrating it with slippers worn a lot in schools, etc., where school-age children spend the most time. It is another object to provide a functional slipper provided with a member.
