Description

Plantar fasciitis insole with care means of plantar fascia}

The present invention relates to plantar fasciitis insoles having plantar fascia protection to reduce pressure from the site of the jagger to the site of the medial arch.

Your feet support your body and allow you to exercise. Therefore, the foot is required not only to support the weight, but also to transmit the momentum when moving, elasticity and elasticity are required. The foot elasticity and the elasticity of the foot are largely related to the foot arch, and the fascia surrounding the inner triangular arch is the plantar fascia.

More specifically, the foot is an elaborate and delicate organ, consisting of about 26 bones, 33 joints, 107 ligaments and numerous muscles and tendons, and the names of the general skeleton of the foot are shown in FIGS. 1A and 1B. 1A shows the skeleton of the foot seen from the back of the right foot, and FIG. 1B shows the skeleton of the foot seen from the side of the right foot.

The recesses in the soles of the feet are called arches, and our feet are divided into three foot arches: the medial longitudinal arch, the lat.longitudinal arch, Has a crossbow. As shown in Figs. 1C and 1D, among these three foot arches, the one closest to the center of the body is called the inner triangular arch and the far one is the outer tribal arch.

These foot arches act as cushions when walking, absorbing shock. In particular, the plantar fascia (Plantar Fascia) is a thick film that statically reinforces the medial arch, starting from the medial projection of the calcaneus and attached to the toe of the toe with the bell, landing in running, jumping, etc. It spreads and contracts again, absorbing the impact of landing. The plantar fascia is burdened with running at the same time as the adduction of the foot (landing of the heel bone) immediately after landing.

Plantar fasciitis is inflammation caused by excessive use of plantar fascia. In other words, plantar fasciitis is a foot disease that is caused by excessive impact or pressure on the plantar fascia, which is the fascia that protects the plantar muscles of the medial arch arch and causes severe pain. Plantar fasciitis is most common in congenital limbs (high foot arches), flat feet, overweight or obese, women who wear high heels, and runners who run or jump a lot (marathons, basketball players, etc.). In recent years, the number of running clubs is increasing.

Therefore, according to the biomechanical analysis of plantar fasciitis patients, insoles for plantar fasciitis that reduce pain and fatigue by reducing the pressure applied to the plantar fascia are desired.

However, above all, the pressure relief of the plantar fasciitis generating site is the basic, stabilizing the foot during walking and maintaining the proper position should be preceded, and plantar fascia protection to protect the plantar fascia area should be provided.

In general, the walking cycle includes the heel contact phase, the foot flat phase, the heel lift phase, the propulsion, toe off phase, swing phase, In the heel folding machine, the foot movements appear in the order of the heel folding machine. In the heel folding machine, the pronation occurs from the supination, and the rotation of the foot occurs at the beginning of the lifting of the heel. In the toe lifter, the toes push the ground and move forward, so our feet repeat this movement.

In some cases, the foot may cause hyperventilation that passes over a period of time when a lot of adduction is due to weight or speed in a change in timing from an abduction state to an adduction state. At this time, the pressure of the jagger protrusion, which is the pressure support part of our body, is increased and the foot is returned to the outside. In order to cause the abduction again in this state of excessive hypertonia, excessive foot lifting motion must occur, which causes the hypertonic abduction of the foot rotating outward. Such over- and over-exercises cause excessive movement of the ankle and cause ankle sprain or distort the balance of the speed and weight bearing of walking, resulting in loss of exercise ability. Therefore, it is desirable for the plantar fasciitis insole to have a posterior control to suppress excessive rotation of the ankle to stabilize the foot during walking.

In general, most of the patients with plantar fasciitis are pain in the medial arch of the foot, unconsciously walking the foot to the lateral margin of the arch, so when walking, the medial can be heard and hyper-abduction occurs. Therefore, the posterior lateral wedge portion, which prevents excessive abduction, is made by dividing the pressure excessively driven into the outer tribal arch area with the inner tribal arch area.

The human foot has an ankle part that connects the lower body and the foot, and the ankle joint is the connection area between the tibia and the foot. The ankle segment usually has a known ankle joint, with a distal guard joint and a subtalar joint under the ankle joint. This subtalar joint is composed of the sustentaculum tali, which is an important site connecting the calcaneus and the talus. Jagger is the most tired part of human walking.

Jagger is shown in FIGS. 1B and 1E. FIG. 1E is an explanatory diagram for comparing the normal position and the abnormal position of the jagger, and FIG. 1E (a) shows that the jagger is in a normal position, that is, perpendicular to the long axis of the foot, that is, 90 degrees. FIG. 1E (b) shows that the jagger is in an abnormal position and does not form 90 degrees with respect to the long axis of the foot. In other words, as shown in (a) of FIG. 1E, the jaggers are normally at right angles to the long axis of the foot, that is, 90 degrees, and the vertebra is surely placed thereon. Jaggeroids are low in height, are not only firmly fixed on the plane, but also have a gentle curve of protruding areas. Most of the body's entire body pressure is sustained in this area, dispersing the power in the forefoot and the forefoot, and the driving force of the movement. This jagger is one of the most stressed areas of human bipedal walking, there is always a high pressure on the foot of the jagger, causing inflammation of the plantar fascia. In patients with plantar fasciitis, pressure is excessively concentrated mainly in the location of the inner triangular arch from the site of the jaw, and inflammation occurs mainly in this area. Therefore, it is desirable to provide plantar fascia protection for reducing the pressure driven from the site with the jagger to the site where the inner triangular arch is located.

The present invention provides plantar fasciitis insoles with foot plantar fascia protection to reduce the pressure of the foot in the hyperabduction state to the normal position and from the site of the jagger to the site of the medial arch.

The present invention provides plantar fasciitis insoles with posterior lateral wedges that allow the pressure to be excessively concentrated only in the lateral triangular arch area so that the pressure is evenly transmitted to the medial arch arch area and prevent over-ablation.

The technical problem to be achieved by the present invention is to provide a plantar fasciitis insole that reduces the pressure of the foot in the position of the medial arch from the site of the jagger to position the foot in the hyper-abduction state.

Another technical problem that the present invention is to achieve is plantar fasciitis insoles equipped with posterior lateral wedge bulge to allow pressure to be delivered evenly to the medial arch arch area and to prevent excessive abduction. To provide.

Another technical problem to be achieved by the present invention is to provide a plantar fascia-type insole having a plantar fascia protection portion for reducing the pressure from the site of the jagger to the site where the inner triangular arch is located.
