MIDTERMS: LE orthosis Flashcards
Devices designed to support, align, prevent, or correct deformities in the lower limb.
Lower Extremity Orthoses
Extends from the foot to the thigh, providing support and stability for both the knee and ankle.
Knee-Ankle-Foot Orthosis (KAFO)
A connection method using a tube in the heel area, allowing for removable uprights.
Caliper Attachment
Controls varus deformities by tilting the hindfoot into eversion.
Lateral T-Strap
Provides support to the knee joint without extending to the foot or thigh.
Knee Orthosis (KO)
Lower extremity orthotic devices specifically designed for children to correct gait abnormalities and structural deformities.
Pediatric Orthoses
Most commonly prescribed lower extremity orthosis, also called a short leg brace. Provides ankle medio-lateral stability and knee stability during gait.
Ankle-Foot Orthosis (AFO)
A U-shaped metal component that is screwed directly to the shoe shank for increased stability.
Stirrup Attachment
Traditional, durable AFO that provides high strength and support but is heavier and requires more energy expenditure.
Metal AFO
Includes mediolateral ankle instability, foot drop, foot slap, and weak push-off at late stance.
Indications for AFO Use
Lightweight, customizable AFO that molds to the patient’s foot shape, offering better cosmesis and comfort.
Plastic AFO
A two-piece stirrup design that allows for easier shoe interchangeability but offers less durability.
Split Stirrup
Prevents excessive upward movement of the foot, assisting weak calf and quadriceps muscles while aiding push-off.
Dorsiflexion (DF) Stop
A stirrup incorporated into a molded foot insert that is placed inside the shoe, providing maximum foot control.
Shoe Insert AFO
Prevents excessive downward motion of the foot, controlling plantar spasticity and contractures.
Plantarflexion (PF) Stop
AFO component that assists dorsiflexion or plantarflexion to support weak muscles.
Ankle Joint Assist
A rigid AFO design that limits ankle movement to provide maximum control and stability.
Solid Ankle AFO
Straps attached to the shoe to correct varus (inversion) or valgus (eversion) deformities.
T-Straps
A posterior knee lock with a lever that allows for hands-free unlocking.
Pawl Lock with Bail Release
Controls valgus deformities by tilting the hindfoot into inversion.
Medial T-Strap
A knee lock mechanism that provides stability by preventing knee flexion when locked.
Drop Lock
A component of a metal AFO that provides support to the lower leg; should be placed below the fibular head.
Calf Band
Adjustable strap used to secure the orthosis to the lower leg.
Leg Cuff
Includes uprights, knee joints, ankle joints, thigh and calf bands, and footplate.
KAFO Components
A knee joint positioned posteriorly to enhance stability by shifting weight behind the knee axis.
Offset Knee Joint
An additional strap that provides support above the patella to control excessive knee motion.
Suprapatellar Strap
Designed to unload weight from the knee and transfer it to the ischium for patients with weak quadriceps.
Ischial Weight-Bearing KAFO
Uses ground reaction forces to stabilize the knee in extension during gait.
Floor Reaction AFO
Designed to unload weight from the ankle and foot by transferring forces to the patellar tendon.
Patellar-Tendon-Bearing AFO
AFO designed to inhibit excessive muscle tone and spasticity in patients with neurological conditions.
Tone-Reducing AFO
Extends from the foot to the pelvis, providing control and support to the lower limbs and hip joints.
HKAFO (Hip-Knee-Ankle-Foot Orthosis)
A pediatric orthotic used to maintain correction in congenital talipes equinovarus (clubfoot).
Denis Browne Splint
A specialized HKAFO that facilitates reciprocal walking for patients with paraplegia.
Reciprocating Gait Orthosis (RGO)
A standing frame orthosis that allows for upright posture and weight-bearing in children with paraplegia.
