1) Excessive knee flexion from IC - midstance
- lack of HS
- frwd trunk flexion
- lateral trunk flexion
- lower cog
2) Absent/ dec knee flexion from IC - midstance
- prolonged foot flat
- hip abd on P Side
- vaulting on sound side
3) Sudden early knee flexion at the end of midstance
- prolong heel off
- prolonged stance phase on sound side
- arrhythmic gait pattern
4) Delayed knee flexion at end of stance
- forward trunk lean
- delayed toe-off on P Side
- dec swing phase on sound side
- sound leg leads
- vaulting on s side
5) Excessive knee flexion prior to toe-off
- pelvic drop, shoulder drop on P side
- prolong stance on s side
- arrhythmic gait pattern
6) Insufficient wt bearing during prosthetic midstance
- prolonged stance on s side
- shortened stance on p side
- prosthesis abducted, cane braced, abducted against s side
TRANSFEMORAL DEVIATIONS
1) Abducted gait
- lateral placement of prosthesis during GC
- inc in width of BOS
- uneven timing
- hip-hiking
- prolonged stance on s side
- vaulting
- moderate lateral lean on p side
2) Circumducted gait
- walking base is normal on double support
- dec knee flexion on p side
- hip hiking on p side
- lateral pelvic drop
- lateral trunk bending toward p side during stance
- unequal timing
3) Uneven heel rise – caused by knee flexion following toe-off
- swing phase is prolonged
- moderate trunk bending towards s side
4) foot-slap following heel contact
- unequal rhythm
- trunk frwd flexion on heel contact
- prolonged stance on s leg
5) Trunk frwd flexion
- trunk leans frwd
- reduced step-length
- hip-hiking
- prosthetic knee flex reduced
- uneven timing
