- What is the primary function of an ankle-foot orthosis (AFO)?
- Controls ankle and foot position and motion during gait
- What motion does a solid (rigid) AFO restrict?
- All ankle motion (dorsiflexion and plantarflexion)
- What does a hinged (articulated) AFO allow that a solid AFO does not?
- Ankle dorsiflexion and/or plantarflexion motion
- What is the primary indication for a posterior leaf spring AFO?
- Mild foot drop, to assist dorsiflexion during swing phase
- What is a knee-ankle-foot orthosis (KAFO) primarily used for?
- Providing knee stability in addition to ankle and foot control
- What population is a reciprocating gait orthosis (RGO) designed for?
- Individuals with paraplegia, to enable a reciprocal walking pattern
- What does a UCBL (University of California Biomechanics Laboratory) orthosis primarily control?
- Hindfoot and subtalar motion
- What condition is a CROW (Charcot restraint orthotic walker) used to manage?
- Charcot foot (neuropathic joint disease)
- What is the purpose of an unloader (unicompartmental) knee brace?
- Shifts load away from the arthritic compartment of the knee
- What position does a resting hand splint hold the wrist and fingers in?
- Wrist extension with fingers in slight flexion (functional position)
- What is the purpose of a cock-up wrist splint?
- Holds the wrist in extension to support a weak or painful wrist
- What region does a TLSO (thoracolumbosacral orthosis) stabilize?
- The thoracic, lumbar, and sacral spine
- What is the purpose of a Philadelphia collar?
- Provides rigid cervical spine immobilization, more restrictive than a soft collar
- What is the primary purpose of a halo vest?
- Provides maximal cervical spine immobilization after severe injury or surgery
- What motion does a Jewett brace primarily restrict?
- Trunk (spinal) flexion
