Foot Orthoses Health Article

Definition

A foot orthosis is an assistive device used in occupational and physical therapy. It is designed to support a person's foot in a way that makes it more functional following disease or injury.

Purpose

Persons with foot and ankle disorders, such as arthritis, ulcers, diabetes, bunions, various forms of tendinitis, and other deformities, can benefit from foot orthoses. Typically, foot orthoses are inlays placed in a client's shoe. The orthosis supports, cushions, and/or pads the foot.

Types of foot orthoses

Most clients with foot problems benefit from mass-produced, prefabricated orthoses. They are relatively common and may absorb shock in the foot or provide added arch under the foot, for example.

Occasionally a prefabricated orthosis is modified in some way to better accommodate a client, and this is referred to as a customized orthosis. These may be molded to better fit a client's foot or have additional padding.

However, some clients with severe foot deformities or disorders may not be able to use a prefabricated orthosis or even a customized orthosis. These clients require custom-molded orthoses that are made from the mold of the client's foot for a perfect, tight fit.

Operation

In order for a client to use a foot orthosis appropriately, he/she must go through a thorough assessment that evaluates the position and range of motion (ROM) of foot and ankle joints in all parts of the foot. Clients should be tested while walking and bearing weight as well as while standing. Clients must be tested for rigidity and flexibility in addition to assessing any foot or ankle pain.
