Foot orthoses are commonly used to treat a variety of foot disorders from overpronation and collapsed arches to plantar fasciitis and other causes of heel pain. The research evidence shows that they are generally pretty good at fixing a lot of the conditions as long as they are indicated for that condition, Foot orthoses usually get used to support the foot, when support of the foot may have nothing to do with the problem that the individual may have. This might lead to them being misused and improperly blamed for treatment failures. Another issue is that there are many different types of foot orthotics and also within each kind of foot orthotic, there is an just about infinite variance in the design features that can be incorporated into them.
If even one of those design features is not good for the individual, then the prospects of that foot orthotic helping is potentially reduced. This is the reason the choice of the different designs is really dependant on the experience and expertise of the medical professional. The medical professional will choose the design features needed for the individual and if the device needs to be custom made for the person or if a mass produced more affordable foot orthotic may be used. With regards to custom made orthotics, the medical professional needs to take a plaster cast or optical scan of the foot kept in specific positions for the foot orthotic to be made on. When it comes to the design of the device different elements are taken into consideration. For example, if the patient has posterior tibial tendon dysfunction, then something like a MOSI type foot orthotic is necessary. The MOSI type has specific modifications to handle the variety of issues that occur in that disorder. When the concern is linked to a lack of impact absorption, then the orthotic ought to be designed to accommodate that. The range of options is endless and depends on the problem present and the experience of the treating clinician.
