✔✔@ Midstance for a BK, if the pylon leans medially, what could be a possible cause of
this deviation? - ✔✔Too much socket adduction
Foot too outset
✔✔@ Midstance for a BK, if the pylon leans laterally, what could be a possible cause of
this deviation? - ✔✔Not enough adduction
Foot too inset
✔✔@ Midstance for a BK, if the patient shows too much varus moment, what could be
a possible cause of this deviation? - ✔✔Foot too inset
✔✔@ Midstance for a BK, if the patient shows too little varus moment, what could be a
possible cause of this deviation? - ✔✔Foot too outset
✔✔@ Midstance for a BK, if the patients feet are too close, what could be a possible
cause of this deviation? - ✔✔Foot too inset
Gait training is needed
✔✔@ Midstance for a BK, if the patients feet are too far apart, what could be a possible
cause of this deviation? - ✔✔Foot too outset
Gait training is needed
✔✔@ Midstance for a BK, if the patients lateral trunk is bending to the prosthetic side,
what could be a possible cause of this deviation? - ✔✔Prosthesis height incorrect
Residual limb pain
Foot too outset
✔✔@ Terminal stance and pre-swing for a BK, if the patients heel off occurs too early
and patient "drops off" too quickly onto the sound side, what could be a possible cause
of this deviation? - ✔✔Foot too posterior
Foot too dorsiflexed
✔✔@ Terminal stance and pre-swing for a BK, if the patients heel off is delayed,
causing hyperextension, what could be a possible cause of this deviation? - ✔✔Foot too
anterior
Foot too plantarflexed
✔✔@ Terminal stance and pre-swing for a BK, if the patients socket drops aware from
the patient, what could be a possible cause of this deviation? - ✔✔Suspension is too
loose
, ✔✔@ Swing phase for a BK, if the foot "whips" medial or lateral during initial swing,
what could be a possible cause of this deviation? - ✔✔Socket is rotated on the patient
✔✔@ Swing phase for a BK, if the prosthetic foot hits the ground, what could be a
possible cause of this deviation? - ✔✔Prosthesis is too long
Suspension is loose
Knee flexion limited
Muscle weakness
Gait training
✔✔If a BK pt says, I feel like I'm walking down a hill... - ✔✔Their socket is too flexed
✔✔If a BK pt says, my knee feels like it wants to buckle... - ✔✔Foot is too dorsiflexed
✔✔If a BK pt says, I can't straighten my knee... - ✔✔Foot is too posterior
✔✔If a BK pt says, I changed to a dress shoe or a boot... - ✔✔Prosthetic foot heel
bumper too firm
✔✔If a BK pt says, I'm being thrown forward... - ✔✔Patient shoe heel to firm or too high
✔✔If a BK pt says, I feel like I'm walking up a hill... - ✔✔Socket is too extended

bumper too soft
✔✔If a BK pt says, I'm falling backwards... - ✔✔Patient shoe heel to soft or too low
✔✔@ Initial contact for an AK, if the patient feels knee instability (knee flexes), what
would be a possible cause of this deviation? - ✔✔Knee is set too far anterior
Heel bumper too firm in the prosthetic foot
Socket flexion does not match contracture
Weak hip extensors
✔✔@ Initial contact for an AK, if the patient has unequal step length (short prosthetic
step), what could be a possible cause of this deviation? - ✔✔Improper prosthetic knee
friction or extension
Unstable prosthetic knee
Muscle weakness
