Gait - unit 3 Flashcards
what is the stride part of the gait cycle
one foot heel strike to the other foot heel strike
what is the step part of the gait cycle
push off one foot to the heel strike of the other foot
what is the stance phase of the gait cycle
begins at heel strike, ends after toe is up
what is the swing phase of the gait cycle
begins when toe comes up, and heel strikes again
what is the double support part of the gait cycle
both feet are on the ground
what is the deceleration part of the gait cycle
begins at heel strike, ends at mid-stance
what is the acceleration part of the gait cycle
beings at mid-stance, ends at toe off
what is the spatial component of gait
distance-related
what are examples of spatial components of gait
length, width, angles
what is the temporal component of gait
time-related
what are examples of temporal components of gait
seconds, velocity, % of time
what happens to gait speed/walking speed as we age
declines
what happens to double support gait as we age
increases (more time spent with feet on the ground)
what happens to stride length as we age
decreases
is double support gait temporal or spatial
temporal - it’s the % of TIME both feet are on the ground
is stride length temporal or spatial
spatial - measured in meters
is clearance spatial or temporal
spatial - measured in cm
is elevation at midswing spatial or temporal
spatial
is lateral step variability spatial or temporal
spatial
what are the 2 angular spatial measures
toe off and foot strike (initial contact)
what happens to toe off angle with age
increases
what happens to initial contact angles with age
increases
what is muscle activity needed for in gait
braking at heel strike, trunk stabilization, propulsion impulse
how is torque of a joint determined
the force acting on it and where/how that force is being applied
