These are more commonly referred to as inserts that are placed in shoes to shift the weight of the feet and legs and bring balance, relieve shock, and minimize stress. They can be rigid or soft, and they can be custom-made or fitted. Also, the orthotic device can come in the form of an actual shoe.

Sometimes referred to as AFOs or foot drop braces, these semi-rigid L-shaped braces stabilize both the foot and ankle to bring muscles and joints into alignment. The braces extend up the calf, and are typically made of metal or hard plastic; they have straps that can connect together to hold the device in place, and bring stability to foot, ankle and lower leg by immobilizing it. These are also used to correct foot drop. AFOs account for 26 percent of all orthotics used in the United States. AFOs include anti-Talus AFOs, Rigid AFOs, Tamarack Flexure Joint AFOs, Solid AFOs, Spiral AFOs, Hemispiral AFOs, Hinged AFOs, Tone-Reducing AFOs, and Posterior Leaf Spring AFOs.

Called HKAFOs, these devices use bands, belts, pelvic girdles and knee-ankle orthotics to help position a person upright while centering the knee joint.

Called KAFOs, these devices stabilize the knee, ankle and foot, allowing for proper function and movement. KAFOs are equipped with mechanically- or electrically-controlled hinges. They are useful when a child has limited movement in his or her legs so they can help when learning to walk.

A brace that is worn to support and align the knee; it extends from above the knee to below it.

If a child needs additional support or alignment in his or her upper torso, a spinal orthotic device can help a child sit up or stand; it is particularly useful if a child has limited trunk control.

Sometimes called THKAFOs, are HKAFOs with spinal orthosis for control over trunk motion and spine alignment, most often used by individuals with paraplegia.

This brace is rigid and has knee hinges; it is used mostly for people who have knee injuries.
