AK Gait Deviations Flashcards
Knee instability at IC
Knee too anterior Insufficient socket flexion Weak hip extensors Foot PF or shoe heel too firm Heel height higher
Foot slap (rapid toe descent) at IC
PF bumper or shoe heel too soft
Habit - driving heel for knee stability
Long sound side step / short prosthetic step
Pain, fear, balance, weakness, habit
Unstable knee
Short toe lever
Insufficient friction
Foot externally rotates in LR
Excessive toe out
Socket rotation (too loose or ML angle too tight)
Weak hip musculature
Donning too rotated
PF bumper of shoe heel too firm, shoe too tight
Toe rotation doesn’t match sound side in MS
Foot rotated
Donning too rotated
Abducted gait in MS
Pain/pressure at ramus or distal lateral femur Lateral wall doesn't support femur Prosthesis too long Socket too abducted Weak/contracted hip abductors Short RL
Lateral trunk lean in MS
Prosthesis too short Insufficient socket adduction Foot too outset Wide ML Socket doesn't support femur Pain at ramus or lateral distal femur Weak/contracted hip abductors Short RL
Hill climbing (pelvic rise) in TS
Toe lever too long
Drop off (pelvic drop w/forward progression) in TS
Toe lever too short
Excessive lordosis in TS
Insufficient socket flexion / hip contracture
Weak hip extensors or abdominals
Short RL (lever arm)
Ischial pain w/weight bearing (socket shape)
Medial whip in PreSw
Knee externally rotated Donning externally rotated Muscle contraction Socket contours (don't accommodate m. contraction) Weakness Silesian belt too tight
Lateral whip in PreSw
Knee internally rotated
Donning internally rotated
Muscle contraction
Weakness
Pistoning at Toe Off
Inadequate suspension
Delayed or inadequate knee flexion in PreSw
Excessive knee flexion resistance
Alignment too stable (knee too posterior)
Uneven heel rise in PreSw
Incorrect knee flexion resistance or extension assist Patient action (too much or little hip flexion)
