Description

Technical Field [0001] The present invention relates to a foot pressure measurement system and method,

More particularly, the present invention relates to a system and a method for measuring foot pressure in a foot and a foot, Foot heel portion, a transverse cusp portion, a cusp portion, and the like.

Generally, in the human body, the foot plays a very important role in maintaining balance and performing various actions, such as supporting the body load and absorbing the impact.

A step is a movement from the contact of one heel to the contact of the other foot. The step width is the distance between the centers of the heels during two consecutive soles of the foot, ie, the distance between the centers of the heels at the time of walking.

Foot angle refers to the angle between the direction of the body's forward direction and the axis of the foot, with the toes pointing outward and assumes a normal range of about 7 degrees.

Shoe worn on the foot should be able to protect the foot by ensuring that the foot pressure due to the load is uniformly distributed throughout the soles of the foot. Since the walking habit, the walking posture, and the shape of the sole are different for each pedestrian, the distribution of the foot pressure is also different from each other.

Therefore, in order to manufacture shoes suitable for each pedestrian, it is necessary to measure the pedestrian's low pressure at the time of walking or the pedestal pressure at the time of stopping, and then the shoes or the insole should be manufactured accordingly.

On the other hand, a foot diagnostic device has been proposed to measure the foot pressure. The foot diagnosis device is disclosed in Korean Utility Model Registration No. 20-395775.

The foot diagnostic system is very simple and convenient to check the overall health of the foot as the subject can see the condition of the footprints on the mirror when the patient is barefooted on the scaffold.

However, there is a problem that the foot diagnosis apparatus can see only the 'appearance' of the foot under load and can not know the specific distribution of the foot pressure or the foot pressure of the 'moving' pedestrian.

In addition, since the thickness is thick, it is not possible to measure the natural low pressure at the time of natural walking and the transportation is not easy.

That is, in order to produce a more comfortable shoe or insole, it is desirable to measure the foot pressure at rest and during walking.

In addition, it is required to be able to mount the pad on a portion where the pressure is biased by quantitatively detecting the pressures of the heel portion, the transverse claw portion, the cervical spine portion, and the like from the sole to the center line.

As shown in Fig. 9, in general, the sole may be divided into left and right center lines (that is, the center line of the foot), or the front and rear legs centered on the lateral center line.

The arches are called arches. The arches have longitudinal arches and lateral arches. The longitudinal arches have medial longitudinal arches and lateral longitudinal arches. Medial longitudinal arches (medial lateral arches) The arch of the lateral mediastinum (the lateral cervical arch) is derived from the calcaneus of the foot and is composed of cubic bone, metatarsal (metatarsal), metatarsal (metatarsus, , The fifth metatarsal). That is, the nearest to the mid-body of the body is the medial longitudinal arch, and the farther is the lateral longitudinal arch. As a result, the medial longitudinal arch and the lateral longitudinal arch are located on the left and right sides of the longitudinal center line (i.e., the center line of the foot) The lateral arch is an arch made up of five metatarsals at the instep and is located in the forefoot. The heel is located in the hind leg. In general, the normal center line of the foot is from the center of the foot to the second toe, or between the second toe and the third toe at the center of the heel of the foot.
