TERMINAL SWING IMPACT insufficient knee friction, too much tension in the extension aid, pt feels that the knee will buckle, forcefull knee flexion
FOOT ROTATION AT HEEL STRIKE prosthetic foot is malaligned, stiff heel cushion, stiff plantar flexion bumper
SWING PHASE WHIPS socket is rotated, knee bolt is rotated, foot is malaligned
FOOT SLAP heel cushion too soft, PF bumper too soft,
UNEVEN STEP LENGTH socket discomfort or poor alignment, hip flexion contracture, hip instability
HIGH HEEL RISE inadequate knee friction, too little tension in the extension aid
LUMBAR LORDOSIS DURING STANCE insufficient support from anterior or posterior walls, painful ischial weight bearing, hip flexion contracture, weak hip extensors or abdominals
FORWARD FLEXION DURING STANCE unstable knee unit, short ambulatory aids, hip flexion contracture
LATERAL TRUNK BENDING DURING STANCE low lateral wall, short prosthesis, high medial wall, weak abductors, abductor contracture, hip pain, short amputation limb
VAULTING - RISE UP ON SOUND LIMB too long prosthesis, inadequate suspension, socket too small, prosthetic foot placed in too much PF, too little knee flexion
