Mod 11-13: Gait & PNF Flashcards
activity that occurs between time heel strike to heel strike on same foot
gait cycle
distance between R and L heel strike
step length (~28 in)
distance between R heel strike and the following R heel strike (an entire gait cycle)
stride length
distance measured between R & L heels during progression of gait
step width (2-4 in)
how fast someone walks
velocity/ distance
of steps one walks over a period of time
cadence/ speed
how long is someone in the single support phase of gait
75% of the gait cycle
how long is someone in the double support phase of gait
25% of gait cycle
how long does the swing phase last during gait cycle
40% of the time
how long does stance phase last during gait cycle
60% of the time
name phases of gait cycle: stance phase (5), swing phase (3)
initial contact, loading response, midstance, terminal stance, pre-swing
initial swing, midswing, terminal swing
name ROM requirements at hip, knee, ankle & great toe
hip: 20* flex, 30* ext
knee: 60* flex, 0-5* ext
ankle: 10* dorsiflex, 20* plantarflex
great toe: 70* MTP ext
initial contact muscle action
concentric quads (knee ext)
concentric dorsiflexors
stabilizing hip extensors & abductors
loading response muscle action
eccentric to concentric quads
eccentric dorsiflexors, then eccentric plantarflexors
concentric hip extensors
midstance muscle action
eccentric plantarflexors
concentric quads & hip extensors (glutes)
terminal stance muscle action
concentric plantarflexors
concentric knee flexors
eccentric hip flexors
pre-swing muscle action
concentric knee flexors
concentric plantarflexors
initial swing muscle action
concentric dorsiflexion, hip flexion, knee flexion
midswing muscle action
concentric dorsiflexors & hip flexors
eccentric hip extensors
(co-contraction at hip)
terminal swing muscle action
eccentric hip extensors
concentric dorsiflexors & knee extensors (quads)
eccentric knee flexors (hamstring)
(co-contraction at knee)
abnormal gait pattern: shortened stance phase causing rapid/shortened step length of uninvolved side bc LE joint pain
antalgic
abnormal gait pattern: balance disruption bc cerebellar involvement; jerky & unsteady movement
ataxic
