Orthotics ankle hip knee Flashcards
What is the goal of any orthosis
address pathological symptoms
orthosis will do one of three things
control pain
Control deformity
control motion
Three points of force application are required to control motion in one plane_ one _____ force and two _____ forces
one corrective force and two stabilizing forces
Foot orthosis
Subtalar joint support in what plane
frontal plane
what are some common indications for FO
pes planus
pes cavus
plantar fasciitis
heel spurs
metatarsalgia
mild-moderate calcaneal varus/valgus
mild-moderate midfoot deformity
laxity
diabetic neuropathy
UCBL- university of cali berkely lab
controls calcaneus and midfoot in what planes
transverse and frontal plane
most corrective foot orthosis
SMO supra malleolar orthosis
controls calcaneus, midfoot in what plane
ankle in what plane
transverse
frontal
ankle fontal
SMO allow for free ______ and ______
dorsiflexion and plantarflexion
What are 3 indicators for SMO
- ankle instability
- flexible calcaneal and midfoot deformity
- moderate-severe deformity
AFO fitting goals
increase ankle stability
improve cadence
increased balance/step length
limit foot drop
increase knee stability
limit genu recuvatum
create heel to toe gait pattern
desire for guided control in 3 planes
What are indicators for metal AFO
ankle motion management: sagittal plane control only
edema: constant fluid fluctuations
Patient preference
What are some contraindications for a metal AFO
increased weight
Posterior leaf spring PLS-AFO indicators
drop foot
tibialis anterior weakness
dorsiflexion paralysis
What are some Pros for PLS-AFO
lightweight
low profile
off the shelf options
Dynamic carbon fiber AFO indicators
drop foot
dorsiflexion/plantarflexion weakness
-cva
-ms
-neuropathy
Solid ankle AFO control what motions
fixed ankle positions for all phases of gait
sagittal
frontal
transverse
Indications for a Solid ankle AFO
- potential or complete paralysis of gastroc/soleus
- mild instability of knee
- deformities of ankle varus/valgus
- contracture spasticity management
- Traumatic LL injury with pain
Ground reaction force AFO
indicators
Crouch gait
quad weakness
knee instability
weak plantarflexors
Articulated ankle foot orthosis
drop foot
need for natural ankle motion
AFOS can have inner booties what are the indications for inner booties
- severe ankle deformity
- sensitive skin, sensory issues
- need for rearfoot or frontal plane control
Arizona AFO: leather ankle gauntlet
indications
- posterior tibia tendon dysfunction
- tendonitis ankle arthritis
- degenerative joint disease
- chronic sport injuries
Charcot restrain orthotic walker
indicators
- charcot joint
- chronic diabetic ulcers
- ischemic necrosis
- fracture management
Richie brace indications
- lateral ankle instability
- peroneal tendinopathy
- cavo-varus deformity
Pressure relief ankle foot orthosis indications
prolonged supine bedrest
prevention of plantar-flexion contraction
maintain neutral hip rotation while supine
not intended for ambulation
