Orthopedic footwear with dynamic medial longitudinal arch support

Abstract

The various embodiments herein provide an orthopedic footwear for correcting a foot deformity. The orthopedic footwear comprises an upper for covering a user's foot, a sole comprising an anterior part, a posterior part and a medial part, and a plurality of Bowden cables for connecting the posterior part and the anterior part of the sole. The sole configured to receive the user's foot. The Bowden cables are configured to vary a height of the medial part of the sole to provide a dynamic support to a medial-longitudinal arch of the user's foot.

Description

SPONSORSHIP STATEMENT[0001]The present invention is sponsored by INSF (Iranian National Science Foundation) for international filing.BACKGROUND[0002]1. Technical Field[0003]The embodiments herein generally relate to an orthopedic device.[0004]The embodiments herein particularly relates to an orthopedic footwear with a dynamic medial longitudinal arch support.[0005]2. Description of the Related Art[0006]Foot plays a very important role in gait, because of its three functions in shock absorption, balancing and muscle force transfer to have optimum body progression. A medial longitudinal arch is the most important biomechanical organizer of the foot during walking. The arch is dynamic and its height varies in the gait cycle. Gait has two phases. The first phase is known as stance in which the foot is in contact with the earth and in the second phase, the foot is not in contact with the earth. In the initial stance, a subtalar joint comes in pronation and the arch height is lowered. In ...

AI Technical Summary

Benefits of technology

[0027]According to an embodiment herein, the Bowden cables are extended in an initial stance of a gait cycle due to a body weight of the user. The medial part of the sole is lowered as the user's foot is in contacts with a ground.

Problems solved by technology

Despite completing the initial stance, the terminal stance of the foot movement is not normal due to an inability of the subtalar joint.

Since the muscle force transition is not optimum and more muscle effort is necessary for body progression thereby resulting a muscle fatigue in consequence.

Other flat foot complications are abnormality in the tarsal bone morphology.

But a lack of supination in a flat foot cases abnormality in the tarsal bones, especially talus and navicular bones morphology.

This change in the joint's biomechanics can cause some degenerative diseases such as knee osteoarthritis and patellof
