Weight acceptance
Which functional task has
–goals
•stability
•forward progression
Single leg support
Which functional task has –goals •forward progression •stability •shock absorption

Which functional task is the most difficult task of gait?
weight acceptance
What are the two temporal measurements?
speed
cadence
Typical adult male cadence
111 steps/min
typical adult female cadence
121 steps/minute
is cadence a good measure of gait quality by itself?
no,
•can have a normal cadence with a very small step length and speed (eg Parkinson’s patients)
what 2 categories of speed are there?
normal
fast
what is the speed of the average adult male?
1.36 m/sec
What is the speed of an average adult female?
1.32 m/sec
what distance measure is
–the sagittal plane distance from initial contact to the next
ipsilateral initial contact
Stride length
what distance measure is
–the sagittal plane distance from initial contact to the next
contralateral initial contact
step length
what distance measure is
–the frontal plane distance
between initial contact points
step width
what distance measure is
–the angle of the foot relative tothe sagittal plane
toe out
average adult male stride length
1.48 meters
average adult female stride length
1.32 meters
what is one of the most sensitive measure of the quality of gait
speed
A speed cut off of ____ predicts future health problems
0.6 m/s
normal step width?
8 centimeters
average toe out angle
7˚
equation to find speed?
speed = stride length x (0.5) cadence
speed and stride length decrease at age
70 years old
