Orthotics: Prefab or Custom-Made?

2008-03-06来源:
you take a simple stroll down the foot product isle at your local drug store you will find an array of foot products and inserts. You will find inserts for cushion, for comfort, for support and for control. Many questions may cross your mind. What are the differences? Is the $15 insert better than the $7 insert? Are these orthotics? Will they help my foot pain? You may take the time to study the package details closely, but in most instances it doesn't really matter which pair you grab. Most of the inserts at the local drug store are essentially the same.

An insert slips into the shoe and will give you some comfort, cushion and a little support. In some cases, inserts purchased at the drugstore will help alleviate some arch or heel pain and give relief to sore, tired feet. But, an insert is not an orthotic. Orthotics are devices which fit into the shoe and aid in foot function. The most important difference is an orthotic controls abnormal motion and corrects foot function, while an insert will only provide cushion and comfort.

A prefabricated orthotic is a device that is pre-made and designed to fit the most common foot types. Typically, a prefabricated orthotic needs to be purchased at a sports store and they are more expensive than inserts, costing $25-$30. The prefab orthotic is more rigid than an insert and is designed not only to support the arch, but also to help control motion, which will decrease stress on the tendons and ligaments in the arch. Many individuals will do very well with a prefabricated orthotic. Prefab orthotics generally last for one or two years before replacement is necessary.

A functional custom made orthotic is a device that is even more rigid than a prefab orthotic. The custom made orthotic must be rigid to help control the motion in the foot and add support. If the orthotic is soft, the weight of the body would collapse the device and it would no longer function. A custom made orthotic is not only custom molded to your foot and arch, corrective wedges and covers are built into the device to help with motion control and to improve the mechanics of the foot. Individuals with flatfeet, tendonitis, plantar fasciitis, certain foot deformities, knee, hip and back problems may benefit from custom made functional orthotics. The orthotic should make standing, walking, jogging or running more comfortable. Custom made functional orthotics will generally last 7-12 years before needing to be replaced, and can cost between $300-$600.

Functional orthotics are a successful treatment for many problems affecting the lower extremity. In a recent article in the Journal of the American Podiatric Medical Association, 75% of patients surveyed had good to excellent results using functional orthotics to treat heel pain, arch pain, arthritis, bunions, pain from flatfeet or high arches, knee, hip and back pain. A recent article in USA Weekend magazine stated the opposite. The article referenced a study in Foot & Ankle International in which researchers followed 874 healthy, young Israeli army recruits without foot problems. The recruits were given soft custom, semi-rigid custom, soft prefab or semi-rigid prefab orthotics to wear in their boots during basic training. The researchers found no difference in the development of foot problems between the custom made orthotic group versus the prefab orthotic group. The conclusion from this study is that custom made orthotics will not help prevent foot problems from developing. What is important to understand is this study did not evaluate individuals with foot pain or foot problems. The population evaluated was a group of young, healthy, active individuals without any existing foot problems. Therefore, we cannot conclude from this study that prefab orthotics treat foot conditions better than custom-made orthotics.

Individuals with plantar fasciitis (heel and arch pain) who also have flatfeet usually respond best to custom-made orthotics. Certain types of tendonitis respond well to orthotics and other types require orthotics. Posterior tibial tendonitis is the tearing and inflammation of the tendon that helps to hold up the arch. When this tendon is overstressed by arch collapse it cannot heal. Custom made orthotics are essential in the treatment of this condition.

Individuals with high arches may also require orthotics, but they do not respond as well. Custom made orthotics can help slow the progression of bunions and hammertoes, but they will not prevent this process. Orthotics may help with some pain at a bunion, but they will not "cure" the bu
