Lecture 21 Flashcards
What is locomotion
What are the primary forms
Important roles in human activities
Walking and Running
What is Gait
Pattern of movement of limbs during locomotion
What is a gait cycle
Single sequence from one heel strike to the next heel strike of the same limb
What is a gait cycle division (walking) involve
Stance phase
Swing phase
What occurs in the stance phase
When the foot is in contact with the ground
What occurs in swing phase
When the foot is off the ground
How much % is the swing phase of the gait cycle
40%
What are the steps of stance phase
Heel strike
Foot flat
Heel raise
Toe off
What are the steps of swing phase
Toe off
Initial swing
Mid swing
Terminal swing
What are the 3 tasks that are performed during one stride gait cycle
Weight acceptance on foot once it is on the ground
Support body weight on a single leg
Advance swing limb in front of body
What are the spatial variables in gait
Step length
Stride length
Step width
What are the temporal variables in gait
Single limb support time
Double limb support time
Cadence
Speed
What is step length
Distance between heel of one foot to the heel of the other foot
What is stride length
What is unique about this
Distance between successive point of heel contact of the same foot
Stride length = 2 x step length
What is step width
Distance between center lines of two feet, perpendicular to the plane of walking
