High-arched foot orthosis

Abstract

A high-arched foot orthosis has two bodies, and each one of the two bodies has a wearing space, a foot portion, an ankle portion, a shank portion, a substrate, and an elastomer. The substrate and the elastomer are disposed adjacent to each other, and surround the wearing space. The substrate extends from the foot portion to the shank portion through the ankle portion. The elastomer inwardly extends from an instep of the foot portion at a cuneiform bone of a wearer through an arch, a sole, and a lateral side of the foot portion in order, wraps over a cuboid bone of the wearer, extends through the ankle portion inwardly combining upwardly toward the shank portion, and wraps over a talus bone of the wearer.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to an orthosis for lower limbs, and more particularly to a high-arched foot orthosis that may correct supination of foot (high-arched foot), external rotation of lower limbs, knee varus, and pelvic tilt and torsion of a wearer.2. Description of Related Art[0002]Some people are born with foot supination, which is also known as high-arched foot (the medial arches of the person are highly arched), and talus abduction combine eversion. An ankle joint and an above-located subtalar joint of the high-arched foot suffer subluxation. External rotations of a tibia and a femur cause knee varus. Furthermore, an acetabulum of a pelvis is pushed by a femoral head of the externally rotating femur, and results in pelvic tilt. The spine will then suffer curved spine compensation due to the tilting pelvis and cause functional scoliosis. Tensions of paraspine muscles and soft tissues of lower limbs of a human body ...

AI Technical Summary

Benefits of technology

The present invention is a device that helps correct high-arched feet by providing a supportive structure that aligns bones and joints properly. This device helps to reduce discomfort, pain, and poor postures, keeping the lower limbs in correct alignment.

Problems solved by technology

Furthermore, an acetabulum of a pelvis is pushed by a femoral head of the externally rotating femur, and results in pelvic tilt.

The spine will then suffer curved spine compensation due to the tilting pelvis and cause functional scoliosis.

Tensions of paraspine muscles and soft tissues of lower limbs of a human body may also be unbalanced.

In a long term, such disorder and inadequate bone and joint alignments will lead to harmful postures to the person, and a series of symptoms may accordingly occur, such as: Achilles tendon pain, shin splints, LCL (lateral collateral ligament) stretch and medial meniscus compression, femoral acetabular impingement, gluteus medius dysfunction, pelvic tilt and torsion, functional leg length inequality, functional scoliosis, psoas major & multifidus stretch and weakness, SI (sacroiliac) joint subluxation & sacroiliitis, HIVD (Herniation of Inter-Vertebral Disc), lumbar facet joint syndrome, soft tissue tightness, spondylolithesis, shoulder elevation compensation dysfunction, CT junction, cervical disc herniation, cervical facet joint syndrome, neck and upper back myofacial problem, TMJ (temporomandibular joint) subluxation, unilateral headache, etc.
