Introduction

What is an orthotic? An orthotic is a device used to mechanically assist, restrict, or control function of the musculoskeletal system [1]. Orthotics come in many shapes and sizes for different parts of the body, whether it be a leg prosthesis used by an amputee or a back brace used by someone with severe scoliosis. A foot orthotic is defined as a mechanical intermediary between the foot and the shoe [1]. Shoes are worn by the majority of our population as a protectant of the feet and specific shoe types can serve to enhance activities including running, hiking, jumping, dancing, etc.

Singularly, the word is orthotic. To pluralize the term, some simply add an 's' to result in orthotics; others, particularly those in the academic community, prefer the word orthoses.
