Gait anaylsis

Question 1

What makes up gait cylce?

Answer 1

stance and swing

Question 2

stance phase

Answer 2

accounts for 60% of gait

part of foot in contact with floor

Question 3

swing phase

Answer 3

when the foot is not in contact with floor

accounts for 40% of gait

Question 4

double support

Answer 4

both feet in contact with ground

accounts for 20% of total gait cycle

Question 5

how is gait measured ?

Answer 5

in distance and time

Question 6

what are the distance variables?

Answer 6

stride length
step length and width
degree of toe out

Question 7

what are the time variables of gait?

Answer 7

stance time
single limb and double support time
swing time, stride and step time
cadence and speed

Question 8

stance time

Answer 8

amount of time during stance phase that elapses of one leg in gait cycle

Question 9

single support time

Answer 9

amount of time that elapses during the period when only one leg is on the ground

Question 10

double support time

Answer 10

amount of time that elapses with both feet on the ground

Question 11

step duration

Answer 11

amount of time spent during a single step

Question 12

cadence

Answer 12

number of steps taken by a person per unit of time

typical : males 110 per min
females 116 per min

Question 13

walking velocity

Answer 13

rate of linear forward motion of the body , which can be measured in meters or centimeters per second

walking velocity = distance walker/ time

Question 14

stride length

Answer 14

linear distance between two succesive events of the SAME extremity

Question 15

step length

Answer 15

linear distance between two successive points of contact of OPPOSITE extremities

aprox 1 m/s

Question 16

step width

Answer 16

linear distance in the frontal plane between midpoint of the heel of one foot and the same point on the other foot

Question 17

toe out angle

Answer 17

angle of foot placement

Question 18

10 meter walk test

Answer 18

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

Question 19

Joint Angles for Gait

Answer 19

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
