technical field

The utility model relates to the technical field of rehabilitation engineering, in particular to an integrated airbag corrective insole.

Background technique

The foot is the base of the human body. It is the same as the foundation of a house. If the foundation is unstable, the structure of the house will be poor. The plantar fascia is like a piece of fan-shaped soft tissue. It is a piece of fascia tissue located between the metatarsal bone and the calcaneus. Its main function is Maintain the height of the arch of the foot and maintain the correct gait posture. Usually, when walking or running, this tissue will bear the pulling force of the body weight that separates the metatarsal bone from the calcaneus, and give the torque required for activities in various situations. Elasticity and absorption of reaction forces with the ground; in addition, during gait, limited ankle dorsiflexion and increased Achilles tendon tension or metatarsophalangeal joint dorsiflexion can cause increased plantar fascia tension, while ankle dorsiflexion After restraint, the patient compensates for the lack of ankle dorsiflexion through excessive pronation of the foot, which results in increased tension in the plantar fascia. When walking barefoot, the center of pressure is initially located in the center of the heel and rapidly increases. The change of the plantar pressure distribution is related to the shoe, and the shoe can reduce its pressure peak by expanding the pressure distribution range of the heel.

Plantar fasciitis is a kind of chronic sports injury. Clinically, patients with plantar fasciitis often have abnormal foot biomechanics (flat feet, eversion feet, high arched feet, hallux valgus, etc.) ); From the point of view of human biomechanics, excessive valgus of the subtalar joint of the foot will cause the arch of the foot to be low and flat, which will pull the plantar fascia and cause inflammation of the fascia. It is tighter than ordinary people and lacks the shock absorption effect. Over the years, it will also cause pain and inflammation due to plantar muscle fascia fatigue, and even severe heel spurs (Heel Spurs).

In fact, many people have more or less problems with their ankles, such as flat feet, high arched feet, hammer fingers, ankle valgus, etc. These diseases of the ankles will affect the stability of the activities of the feet, so they will As a result, there is a curve shock in the pressure center of the foot, and it will also cause great damage to the plantar fascia.

At present, functional insoles and orthopedic insoles have great limitations in walking physical examination, orthopedic effect, and cost. Most functional insoles focus on cushioning plantar pressure, sweat absorption, deodorization, and comfort. Orthotics and plantar fascia symptoms are rarely treated; while the existing orthopedic insoles have a single function and cannot achieve precise correction, and are less involved in plantar fascia symptomatic problems. Most insoles can only relieve plantar fascia symptoms. , but the effect is not good, and there is no better biomechanical approach to fundamentally solve it; in addition, although smart insoles can achieve precise orthopedic effects, they are less effective in solving plantar pressure and comfort, and the cost of smart insoles is high. , Not easy to maintain.
