Gait Flashcards
Terminal stance
last phase of single support
Mid-stance
Single support body advancing
Terminal swing
Last third knee extends and limb positioned for weight acceptance
Initial contact
foot strikes ground
3rd rocker
Terminal stance to heel off
Pre-swing
Double support with knee rapid flex
What are Kinematics
Angles of joints and segments in 3 planes
What is one Stride
One limb initial contact to initial contact same limb
Some determinants of gait: Perry, Winter, Gage etc
Stable weight bearing leg Single limb support Balance of head, arm, trunk Clearance Pre-positioning for initial contact
What is Speed
Distance per second (Meters/Sec)
How do you define running
No double support
How long is swing period
40%
When does gait cycle end
When the initial limb once again makes initial contact
What are the characteristics of a mature gait
- Increased speed (distance/time)
- Increased step
- Increased single support
- Less wide
- Decreased Cadence (Steps/time)
What is a Step
One limb initial contact to next limb initial contact
1st rocker
Heel strike to flat foot
Perry: 8 phases of gait
- Initial contact
- Loading resopnse
- Mid-stance
- Terminal stance
- Pre-swing
- Initial swing
- Mid-Swing
- Terminal swing
When does gait cycle begin
One foot initial contact
How long is stance period
60%
Initial swing
1st third of swing with max knee flex
What is Cadence
Steps per minute
Calculate bladder
Agex30 plus 30 in ml
Normal adult 400 -600
What are gait Kinetics
Forces
2nd rocker
Shifting over planted foot mid stance
