Gait anaylsis Flashcards
What makes up gait cylce?
stance and swing
stance phase
accounts for 60% of gait
part of foot in contact with floor
swing phase
when the foot is not in contact with floor
accounts for 40% of gait
double support
both feet in contact with ground
accounts for 20% of total gait cycle
how is gait measured ?
in distance and time
what are the distance variables?
stride length
step length and width
degree of toe out
what are the time variables of gait?
stance time
single limb and double support time
swing time, stride and step time
cadence and speed
stance time
amount of time during stance phase that elapses of one leg in gait cycle
single support time
amount of time that elapses during the period when only one leg is on the ground
double support time
amount of time that elapses with both feet on the ground
step duration
amount of time spent during a single step
cadence
number of steps taken by a person per unit of time
typical : males 110 per min
females 116 per min
walking velocity
rate of linear forward motion of the body , which can be measured in meters or centimeters per second
walking velocity = distance walker/ time
stride length
linear distance between two succesive events of the SAME extremity
step length
linear distance between two successive points of contact of OPPOSITE extremities
aprox 1 m/s
step width
linear distance in the frontal plane between midpoint of the heel of one foot and the same point on the other foot
toe out angle
angle of foot placement
10 meter walk test
patient walks 14 m and is timed to see how long it takes to walk 10 m
4 of the m are doe acc and decel
gait speed more than 1 m/s is common reference for increased fall risk
Joint Angles for Gait
Hip ROM 20 deg of flx and ext
Knee ROM straight 0 deg and 60 deg flx
ankle ROM from 25 deg plantarflex to 7 deg dorsiflx
if these joint angles are limited , gait pattern will be considerable abnormal
