guarding
use of 2 force vectors
2 on one side, one on the opposing
important principles - ANSWER: 1. always select the least restrictive option
2. safety: know a person's mentation, sensory ability, visual ability, bony deformities,
and edma issues

ankle foot orthoses - ANSWER: plastic/ MAFO's
Metal
Plastic/ MAFO's - ANSWER: skin risk concerns
light weight
cosmetically favorable
custom made
, can utilize in different shoes
trimming possible
not great with edema- edges
Metal - ANSWER: (AFO's with shoes/ metal upright)
accommodates edema fluctuations and skin concerns
may accommodate heavier loads/ bariatric clients
orthopedic shoes come as part of brace
variability of cuff size, metal upright joints, shoe variations
Molded ankle foot orthosis (MAFO) - ANSWER: may be identified by:
flexibile, semi-rigid, rigid
solid/ hinged (no channels)/ articulating (channels)
anterior/ posterior coverage
foot coverage/ support
off the shelf/ custom made
other specifics as indicated (floor reaction etc.)
leaf spring MAFO - ANSWER: correction of foot drop
flexible at foot
flexible/semi rigid for toe clearance during swing
distinctive shape with thin post support
often off the shelf
most simple
swedish ankle foot orthosis - ANSWER: cut out in calf and heel
off the shelf (available in sm/md or md/large)
50 $
precaution for sensory and skin fit given cut outs and plastic
minimal sizing options
delivers mod. lateral stability and assists with dorsiflexion
hinged/ articulated MAFO - ANSWER: allows for DF but stops swing at neutral, allows
toe clearance in swing does not affect stance
may incorporate klenzack mechanism for more customization
floor/ ground reaction MAFO - ANSWER: custom, rigid
anterior tibial enclosure to prevent forward tibial advancement in close chain of
stance/ prevent knee buckling while also preventing toe drag in stance
skin concerns
could have ant. tibial portion on cuff, but that's less support
Metal AFO varieties - ANSWER: identified by:
single vs. double metal upright(s)
single vs. double klenzack - ant./ post., open channels, stops/ pins and locations,
springs and locations, combo
other features
