Utilization of AFO in Rehab Flashcards
If a trim line is cut more anteriorly what affect will that have on the AFO?
it will create a stiffer AFO
If a trim line is cut more posteriorly what affect will that have on the AFO?
it will create a more flexible AFO
When are conventional orthoses used?
for someone with fluctuating edema
What are supramalleolar orthosis?
trimlines extend above malleoli, used when M/L stability is needed, requires voluntary able control
common in pediatrics
When are prefabricated ankle orthoses recommended?
for mild and temporary cases
What is a solid AFO?
fixed at ankle and provide support for TCJ/STJ
DF AFO can reduce recurvartum at knee
usually with anterior trim as it allows for more control but will not be a smooth gait
Why would a motion articulated AFO be utilized?
allows for DF and/or PF, most often allowing DF but blocking PF with posterior stop
also more energy efficient
When are motion articulated AFO contraindicated?
if a pt has a contracture
Where is the trim line on a dorsiflexed AFO?
posterior to malleoli
provides a spring like DF assist in late stance
When are carbon fiber AFO indicated?
if pt has fluctuating edema or skin issues as they are ultra light weight
provide spring like affect and translates to smoother gait
What is a carbon fiber AFO contraindicated?
if pt has M/L ankle instability
When would a ground reaction force AFO be prescribed?
used to prevent excessive knee flexion, KE promoted by use of GFRV,
What is the average time it takes a patient to get adjusted to an AFO?
2 weeks
What is a wearing schedule for an AFO?
day 1/2- limited WB, 15-30 intervals
day 3/7- intermittent WB, 15-30 intervals
day 8/14- extended WB periods as indicated
