Orthotics
Description
An orthotic is designed to improve the mechanics of the foot . Its purpose is to prevent abnormal motion of the foot while allowing for normal motion and function.
The most common treatment for biomechanical problems is the use of special shoe inserts known as orthoses, or more commonly, orthotics. They assist the feet to function more efficiently. They do this by controlling joint movement, and by altering some joint angles to prevent excessive motion.
Many look like arch supports, but they are not intended to support the arch. Orthotics are angled individually to control the heel and forefoot, and prevent excessive motion. The natural arch in the foot will in most cases become more apparent whilst the orthotics are worn.
There are many different types of orthotics. The type that is used depends on the activity in which the patient is involved, the shoes they want to wear, and the underlying foot problem.
Orthotics are made from impressions of the feet.
Orthotics fall into three broad categories: rigid, soft and semi-rigid.
- Rigid orthotics are designed to control function.
- Soft orthotics help absorb shock and take pressure off uncomfortable or sore spots.
- Semi-rigid orthotics provide dynamic balance of the foot while walking or participating in sports.
