LE Prosthetics Flashcards
biomechanical deficits in gait with partial foot amputation
- reduced plantar WB surface
- impaired pron/sup
- loss of active push-off
what AFO could be used for great toe amputation?
tibial tubercle height AFO
which BKA amputation can be WB on?
Symes ankle disarticulation
what is the weight distribution of WB for BKA?
50% patellar tendon
20% tibial flare
30% tissue
50% of WB should be on ____ for AKA
ischial tuberosity
pressure sensitive areas for AKA
pubic ramus
symphasis pubis
adductor tendon
lateral distal femur
types of suspension
- suspension sleeve
- pin lock
- harmony/VASS
- suction/seal in
K level for SACH foot?
K1 or cost effective
K level for single axis foot?
K2, K3
K level for flexible keel foot?
K2
K level for multi-axis foot?
K2, K3, K4
K level for dynamic response foot?
K3, K4
K level for MPK foot?
K3, K4
which foot is good for uneven surfaces & ramps?
multi-axis foot
benefit of single axis foot
foot flat quickly –> promote knee extension
K level for weight activated safety knee?
K2
K level for 4 bar knee polycentric knee?
K2
benefit of polycentric knee?
shank shortens during swing
K level for hydraulic knee?
K3, K4
K level for microprocessor knee (C leg)?
K3, K4
benefit of microprocessor knee (C leg)
stance control - prevent falls
check length of what landmarks for alignment?
PSIS, ASIS, greater troch, iliac crests
good dynamic alignment includes:
- knee slightly flexed
- toe out match
- equal weight on both sides
- assessed in midstance w/ foot flat
list what each K level means
K1 - transfer only
K2 - household ambulation
K3 - community ambulation
K4 - exceeds normal ambulation (ex: athletes)
