Flashcards in Gait Cycle Deck (19)
Normal distance for base of support
6-10 cm, measured between both heels
The time when only one foot is in contact with the floor
Single limb support
How much is the COG displaced horizontally and vertically during a normal step?
5cm horizontally and 5 cm vertically
5 phases of stance phase
I Like My Tea PREsweetened
1. Initial contact
2. Loading response
4. Terminal stance
What is considered a comfortable walking speed?
3 mph or 80m/min
During the gait cycle, how much %age is the swing phase and how much %age is the stance phase?
Stance = 60%
Swing = 40%
Where is the center of gravity typically located in relation to the S2 vertebra?
COG is 5 cm anterior to S2 vertebra
As walking speed increases, how does the stance phase and swing phase change?
Stance phase decreases and swing phase increases
What part of the gait cycle does the body have the lowest center of gravity?
The Loading Response
The time when both feet are in contact with the floor is known as
Number of steps per unit time is known as...
Stride length vs step length
Stride = heel strike of one foot to heel strike of the same foot
Step = heel strike of one foot to heel strike of the other foot
The gait cycle is made up of what 2 phases?
Stance phase and swing phase
What part of the gait cycle is COG the highest?
What happens to time period of double limb support as walking speed increases?
Double limb support decreases
At midstance, where does the ground reactive force vector go in relation to the ankle, knee and hip?
Anterior to ankle
Anterior to knee
Posterior to hip
Normal step length
What change in the gait cycle is a person considered running?
When there is no double limb support period
