Gait Analysis
Gait Cycle
Models (2)
Alternative
aka
Ranchos Los Amigos
Traditional
Difference between stride and step
stride
Events taking place between successive contacts of the same foot
how many strides in a gait cycle
1
step
Events taking place between contacts of opposite feet
how many steps in a gait cycle
2 (right and left)
spatial descriptors (4 terms; definition after)
stride length
Distance between two successive contacts of same foot
normal value
72 cm (28 in)
step length
Distance between two successive contacts of opposite feet
step width
lateral distance between heel centers on two consecutive foot contacts
what is the normal range
Normally ranges from 7-9 cm
foot angle
Angle between line of progression and long axis of the foot
aka
degree of “toe out”
what degrees is normal
7 degrees
temporal descriptors (4 terms; description right after)
cadence
aka
step rate
Number of steps/min
normal value
1.87 steps/s (110 steps/min)
stride time
Time of a full gait cycle
step time
Time to complete a right or left step
reciprocal of what
Reciprocal of cadence in normal, symmetrical gait
walking speed
amount of distance covered in a given period of time
4 variables
age, sex, height, weight
typical units of measure (2)
Meters per second (m/s)
Miles per hour (mph)
normal value
1.37 m/s (3 mph)
2 strategies to increase walking speed
increase stride (step length)
increase cadence (step velocity)
what is the most basic temporal descriptor
cadence
Other Info
all measures of gait depend on what
walking speed
women usually exhibit what 4 things related to gait
Slower speed
Shorter step length
Faster cadence
Likely because of anthropometric differences
even c matched anthropometrically, woman displays what 2 things
increase cadence and increase step length at standard speed
