Gait Flashcards
Distinguish cause of post trunk lean (ext) in initial contact/loading/mid stance, terminal swing phase vs terminal stance/pre-swing, initial swing phase
Initial contact/loading/mid stance.terminal swing due to glute weakness (hip ext)…notice all related to stance (even terminal swing, flexion is decreasing atp)
Terminal/pre swing/inital swing due to hip flexor weakness (spring mechanism)
Typically there is eccentric control of muscles on the opposite side
of direction being moved
e.g pf controling DF to avoid foot slap or flat foot
e.g trunk extensors and hip extensors working during forward progression during early phases
e.g quads controlling when knee bends due in loading phase
Compensation for pes equines
Forward trunk lean or lordosis to get over toe when in excessive PF
in terminal phase for example
Excessive pronation due to
Rearfoot varus and forefoot valgus
How does weak DF impact the heel in terminal stance
Early heel-off compensation to progress forward (instrad of just falling into DF)
How does weak PF impact the heel in terminal stance
Heel does not come up on time b/c can not push off
Which part is the swing phase is knee flexion the highest
initial swing (60 degrees) decreases after this point
Steppage gait
Scuffs toe box b/c stuck in PF so dragging there
Mid swing and terminal swing include what
Deacceleration (eccentric of hip extensors) concentric quads to straigthen for loading response
Toe in gait
seen with femoral anteversion
Toe out gait
seen with femoral retroversion
Retro there is an O
1st MTP extension must be
60
Turf toe is e.g of somehting that would prevent that (hallux rigid)
Terminal stance compensation
Forward trunk lean to get on top of COM if PF contracture, pes anquines
Weak PF can cause delayed
elevation of heel in terminal stance
Lack of DF can cause
early heel off in terminal stance
Backwards lurching
Terminal swing, pre-swing, initial swing due to weak hip flexor this helps get them forward by changing MA
Knee
Goes towards 0 extension in midswing and terminal swing b/c preparing for the initial contact
Sitting pelvic height being equal suggests the discrepancy arises when the patient is weight-bearing, pointing to a functional or structural issue like a leg length discrepancy.
