|
Definition
| unloads metarsal heads for metatarsalgia |
|
|
Term
| what are sulcus length insoles |
|
Definition
| sulcus length ends behind metatarsal heads for tight dress shoes |
|
|
Term
|
Definition
| add saline, and there is a chamber that swells |
|
|
Term
|
Definition
| cleats have a low heel counter, so you can't put anyting extra in the shoe that would lift the heel up higher out of the shoe. Instead, grind down cleats. |

Term
| what can you do to a fastech orthotic after you've molded it to someone's foot |
|
Definition
| put whatever you want to under it. Usually artificial cork |
|
|
Term
| why add cork/stuff to the bottom? |
|
Definition
| cork helps supprt the shape that you have. If you don't add cork, the orthotic is only semirigid |
|

Term
| what is the recipe for a happy diabetic foot? |
|
Definition
| total contact inside the shoe. Make sure there's not excessive motion that brings them over to a specific area of the foot. Stiff, rigid shoe with a little bit of forefoot rocker/convexity. |
|
|
Term
| what is the main concern for a diabetic foot |
|
Definition
|
|
Term
| how to decrease the likelihood of pressure ulcers in diabetic foot |
|
Definition
| decrease the force with shock absorbing materials. Increase contact area. |
|
|
Term
| how to increase contact area? |
|
Definition
| increase contact area with cushy parts of the foot, like the arch. Find out what's driving abnormal movements such as pronation and fix it |
|
|
Term
| is it better to have a stiff or flexible shoe for a diabetic |
|
Definition
| stiff shoe with rocker bottom toe is best. If shoe is flexible, all contact area goes into metatarsal head |
|
|
Term
| what to do if someone has metatarsalgia |
|
Definition
| put a metatarsal pad just behind the affected metatarsal head to add cush |
|
|
Term

Definition
| pain, numbness, tingling at the interdigital nerves |
|
|
Term
| describe the path of the interdigital nerves |
|
Definition
| juncture of nerve tissue as it approaches the web space of the webbing of the toes, splits, and goes up the sides of the insides of the toes. |
|
|
Term
| how to test for morton's neuroma |
|
Definition
| squeeze metatarsal heads together, dig into the web space between affected diits |
|
|
Term
| what are 2 uses of metatarsal pads |
|
Definition
| decrease contact pressures on metatarsal heads, separate adjacent metatarsals to decrease mechanical irritation of a neuroma. |
|
|
Term
| what questions to ask when making/placing a metatarsal pad |
|
Definition
| how high should the apex be, where should it go, how large should the circumference be |
|
|
Term
|
Definition
| a wooden form on which a shoe is made |
|
|
Term
| is a curved last better for pronators aor supinators and why? |
|
Definition
| better for supinated because a curved last is more flexible. Foot will not provide good shock asorption so you try to get it from the shoe. Also in supination, the forefoot is adducted on the rearfoot |
|
|
Term
| is a straight last better for pronators or supinators and why? |
|
Definition
| better for pronators because it pushes against the medial parts of the foot that want to pronate in medially. |
|
|
Term
| what kind of heel coutner shouuld pronators get |
|
Definition
|
|
Term
| what is a combination last interface |
|
Definition
| straight line connecting upper to back, closer to the front |

|
Term
| what is a dual density midsole |
|
Definition
| stiffer midsole material medially to resist eversion of the shoe on the ground |
|
|
Term
|
Definition
| bridgework outside the shoe at the medial arch to prevent movement. |

Term
|
Definition
| reducing the forces that come down on the foot |
|
|
Term
| why do stiff shoes not reduce the forces that come down on the foot |
|
Definition
| F=m x v/t. if the shoe is stiff, t will be small and increase the force |
|
|
Term
| why not buy shoes years in advacne |
|
Definition
| EVA materials deform overtime |
|
|
Term
| what is posterior heel flare |
|
Definition
| distance of posterior part of shoe from posterior part of ankle |
|
|
Term
| how does a large posterior heel flare affect the need for dorsiflexion |
|
Definition
| the posterior heel flare creates a longer moment arm for plantar flexion, calling for greater concentric/internal control with dorsiflexion |
