contraindications for SACH foot - <<ANSWER>>active users; when inversion, eversion,
and torque are needed
advantages to SACH foot - <<ANSWER>>-durable, low maintenance, low cost
-several heel heights
-several activity level categories
disadvantages to SACH foot - <<ANSWER>>-soft material breakdown
-minimal energy return
-no multi-axial abilities
-can get maxed out with obese patients
single axis articulated ankle (K2) - <<ANSWER>>similar to SACH foot, but allow
plantarflexion and dorsiflexion with use of bumpers for control
indications for single axis articulated ankle - <<ANSWER>>-knee stability
-all K levels
-adjusts joint angle for uneven terrain (sagittal plane only)
contraindications for single axis articulated ankle - <<ANSWER>>active users; when
inversion, eversion, and torque are needed
advantages to single axis articulated ankle - <<ANSWER>>-knee stability (weak quads)
-all K levels
-adjusts joint angle
disadvantages to single axis articulated ankle - <<ANSWER>>-needs maintenance:
bumper replacement
-can be heavy
multi-axis articulated foot (K2) - <<ANSWER>>-similar to single axis, but now has some
inversion and eversion capabilities
indications for multi-axis foot - <<ANSWER>>-torque absorption, inversion, eversion
-uneven terrain
-K2 and above
contraindications for multi-axis foot - <<ANSWER>>when patient can use MORE
advantages to multi-axis foot - <<ANSWER>>-shock and torque absorption
-foot conforms to surface
disadvantages to multi-axis foot - <<ANSWER>>-costly
-needs maintenance
, dynamic response foot (K3) - <<ANSWER>>-returns more stored energy than lower
functioning feet
indications for dynamic response feet - <<ANSWER>>active ambulators K3 and above
advantages to dynamic response feet - <<ANSWER>>-smoother gait
-returns stores energy - aids in propulsion
disadvantage to dynamic response feet - <<ANSWER>>costly
microprocessor foot (K3) - <<ANSWER>>-computer-controlled
-has sensors, motors, and springs
-limited to single axis motion
advantages to microprocessor feet - <<ANSWER>>-able to continuously monitor and
adapt to changes in motion
disadvantages to microprocessor feet - <<ANSWER>>-heavy
-needs charging
-limited to single-axis motion
-contraindicated in exposure to water, dirt, extreme heat
A firm PF bumper or firm heel can result in what change in the gait cycle? -
<<ANSWER>>increased flexion of knee in LR
A soft PF bumper or soft heel can result in what change in the gait cycle? -
<<ANSWER>>late flexion of knee in stance
heel lever - <<ANSWER>>the perpendicular distance from roughly the heel cushion to
center of socket
toe lever - <<ANSWER>>the perpendicular distance from the end of the keel to center
of socket
What are some anterior pressure tolerant areas? - <<ANSWER>>patellar ligament,
medial tibial flare, medial shaft of tibia, anterior compartment
What is a lateral pressure tolerant area? - <<ANSWER>>lateral shaft of fibula
What is a posterior pressure tolerant area? - <<ANSWER>>posterior compartment
(gastroc musculature)
