TRANSTIBIAL GAIT DEVIATIONS

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
