Biomechanics
This joint’s motion in weight-bearing includes calcaneal eversion, talar adduction, and tibial internal rotation.
What is the subtalar joint during pronation?
This reinforcement is added to support the medial longitudinal arch.
What is the saddle/arch bandage?
The base length for most accommodative orthoses.
What is full length ?
An orthosis that encases the midfoot, subtalar and tibiotalar joint. It restricts calcaneal and subtalar joint motion.
What is a lace-up/gauntlet orthosis?
The type of orthosis that can control frontal and sagittal plane motion and is used for significant knee and hip weakness.
What is KAFOs?
The three arches of the foot are the MLA, lateral longitudinal arch, and this third arch.
What is the metatarsal arch?
This part of the upper part of a shoe is important for accommodating common foot deformities such as hammer toe and claws.
What is the toe box height?
This type of orthosis controls abnormal forces in frontal and transverse planes.
What is a 3-pt counterforce foot orthosis?
What is a posterior leaf spring AFO?
The pt is having medial knee pain. This orthosis would be appropriate.
What is an offloading knee orthosis?
This fixed foot deformity is characterized by calcaneal inversion, talar abduction & talar DF and ER of tibia.
What is pes cavus?
This type of heel compresses/absorbs shock and is usually recommended for use w/ most LE O and P devices.
What are low broad heels?
This 3 pt counterforce foot orthosis restrains midfoot pronation and forefoot supination, controls hyperpronation and valgus, and corrects rearfoot valgus.
What is a SMO (supramaleolar orthosis)?
What is a spiral ankle AFO?
This knee joint component keeps the GRFV anterior to knee during stance but does not interfere with swing.
What is a posterior off-set knee joint?
The subtalar joint is not in neutral in this phase of gait.
What is midstance?
What are shoe lasts?
The best time of day to evaluate shoe/insert.
What is late in the day?
This orthosis is used for patients with quad or GSS weakness, controls ankle and knee and uses a 3 pt counterforce system to stop dorsiflexion.
What is an anterior floor reaction AFO?
This type of KAFO allows for reciprocal gait patterns by coupling hip joint motion.
What is a reciprocating gait orthosis (RGO)?
If hindfoot varus is present, then this part of the foot must pronate to bring it down to the ground.
What is the forefoot?
If Gilbert has a lateral heel wedge on his right shoe, then this wedge shifts the COP of medially during WB to correct this deformity.
What is flexible rearfoot varus?
This orthotic system is often molded using foam impressions or digital scans and provided by third-party companies.
What is a full-custom orthotic?
Before prescribing an AFO, make sure you determine clear functional and specific orthotic goals based on what assessment of the client.
What is functional and biomechanical assessment?
This KAFO is unsafe if the patient has uncontrolled spasms.
What is a scott craig orthosis?
