Orthotics for Adults Flashcards
Indications for a rigid AFO
Severe dorsiflexion weakness, quad weakness and moderate to sever plantarflexion inversion tone.
Limitations for a rigid AFO
BULKY, difficulty donning for some, need larger/wider shoe due to bulk, no ability to bend ankle, limited for squatting.
Indication for ground reaction force AFO
Moderate to severe quadricep and DF weakness.
Limitations of ground reaction force AFOs
descending stairs and squatting
What is the goal of a ground reaction force AFO?
Keep the knee from collapsing
Indications for a posterior leaf spring AFO
Mild to moderate dorsiflexion weakness
Limitations of a posterior leaf spring AFO
Not effective for large or heavy frames individuals given the increased forces. Not made for equinovarus or quad weakness
Indications for a hinged/articulating AFO
Moderate to severe dorsiflexion weakness and moderate to severe plantarflexion inversion tone.
Limitations for a hinged/articulating AFO
BULKY. Not for quad weakness
What is special about a hinged/articular AFO?
Allows for dorsiflexion, tibial advancement, and knee flexion.
Indications for a single/double strut DF assist AFO
Significant plantar flexor tone and extensor tone with poor foot clearance.
What type of AFO is typically attached to a particular shoe?
A single/double strut DF assist AFO
3 contexts for the use of a heel lift:
- In conjunction with AFO to increase anterior tibial angle to improve knee flexion during gait.
- Used to level leg length
- Used to level leg length due to AFO height asymmetry
Indication for a Swedish knee cage
Strong knee extensor tone
Poor sensory feedback for knee protection
Can be used in conjunction with AFOs
What does the Swedish knee cage do?
Blocks knee extension moment, prevents genu recurvatum
