S2 L6: Foot Orthosis (FO) Flashcards
3 function of foot in gait
- Shock absorption
- Adaptation to surface
- Propulsion
_____ ______ are appliances that apply forces to the foot. Whether immobilized, corrects, or makes the feet adjust to several environments during ambulation.
Foot Orthoses
Purposes of foot inserts
Pain relief & too improve the wearer’s transition during stance phase
Internal modifications inside the shoe made of resilient materials to reduce impact shock and shear, brought about by ambulation due to the ground reaction force.
Inserts
T/F: Foot inserts are recommended for pt who suffers from diabetic neuropathy.
True
This type of foot insert acts like a second skin. It tends to reduce gait unsteadiness by improving proprioception from the increased foot contact area.
Full-length insert (full length orthosis)
T/F: Full-length insert (full-length orthosis) is used to relieve pain and activity limitation particularly associated with PES PLANUS or individuals who have a very high arch deformity.
False.
Pes Planus —> Pes Cavus
An increased caved position of the longitudinal arch, most common is the Medial Longitudinal arch
Pes Cavus
Pt suffers from flat foot deformity.
Pes Planus
Internal modification inserted inside the shoe and is placed along the metatarsals.
Metatarsal Pad
The convex component protects the metatarsal pad from ______ during the ground-reaction force in _____.
- Heating too much
- Stance Phase
What does metatarsal pads reduce?
- Reduces plantar pressure especially for pt’s who suffers from insensitivities such as cases like diabetic neuropathy.
- Reduces tension on MT heads.
What are the main disadvantage of internal modifications?
Tt reduces shoe volume. Shoes can be tight especially if the insert is thick.
What is one advantage of internal modifications?
It does not affect the aesthetic appearance of the shoes, unlike external modifications.
Like the full-length insert, it is intended to prevent depression of the subtalar joint and flattening of the arch. Helpful for patients with Pes Planus.
Longitudinal Arch Supports
What is the difference of Longitudinal arch supports and full length supports?
Longitudinal arch does not cover the entire foot. It is only intended to assist the longitudinal arch if there is a flattened portion.
It is the primary keystone for the medial longitudinal arch.
Scaphoid
Presentation of the scaphoid when a pt has pes planus.
Depressed.
Modification given specifically if there is a depressed scaphoid bone. To correct a flat medial longitudinal arch.
Scaphoid Pad
Recommended support when pt does not only suffer from a depressed scaphoid, but also weakness of the plantar muscles and other structures of the MLA.
Longitudinal Arch Support
Much rigid type of an internal modification to address midfoot issue or a posterior tibial malfunction
