class three: abnormal gait Flashcards
1 gait cycle is equal to what
1 stride length - 2 steps
gait deviations - tightness
early movement then expecteed
gait deviation - weakness
later movements then expected
early toe off in midstance what could be the issue
PF tightness (calf tight)
early toe off in midstance what could be the issue
hip flexion contracture
is knee valgus caused by weak abd or weak vastus medialis
weak hip abd
what is the role of the glute max in gait
used in initial stance phase
eccentric contraction - deccforward momentum
what is the role of the erector spinae in gait
heel strike through toe off
maintain trunk posture
what can cause a backward lean in stance phase of gait
weak hip extensor (lean over the weak muscle)
rigid hip flexion contracture - accommodation of this, this causes an anteior pelvic tilt and subsequent lordosis
swing phase - backward lean
weak hip flexors
stance phase - lateral trunk lean
weak hip abd
stance phase - forward trunk lean
weak hip flexors
stance phase - backward trunk lean
weak hip extensors
what is the function of the peronals during stance phase
maintain medial and lateral movement of the foot
foot instrics role during stance phase
concentric contraction support the plantar fascia
