Foot supports are commonly used by many different professions to take care of a number of problems that can affect the foot and lower limb. They are often used if there is an issue with the biomechanics or posture of the foot that may be modified to improve posture or function. It is generally believed that when the feet are out of position a whole range of problems can affect the feet and lower limb. Not everybody needs foot orthotics, so the decision as to when they should be used is based on on the nature of the foot and leg problem and the relationship of the foot posture to the problem.
There are almost as many different types of foot supports as there are feet. The options are countless. It is easy to get a foot orthotic over-the-counter from various sorts of stores and it is almost a matter of luck if what you buy is the correct one for your foot type and the character of the condition that you have got. Many specialists do suggest these types of mass produced products for the simple easy to deal with foot symptoms. Nonetheless, if the foot structure and the type of the problem is more intricate, then a custom made foot insole is normally indicated.
How a clinician decides on which kind to use is normally based on a extensive clinical evaluation taking into consideration the structure of the foot and the nature of the complaint. Even apparently straightforward choices for example how firm the foot supports should be is complicated. Those who need foot supports typically like the less rigid ones since they are more comfortable, but the flexible it is, the more likely that it is not likely to help. The clinical assessment, called the Supination Resistance, is often used to attempt to work out how rigid a foot insert is needed to work to alter the foot. If you need foot inserts, then it's probably better to get evaluated by a experienced specialist.
