GAIT Cycle Flashcards
Cycle of movements in walking is usually divided into two phases:
Stance and Swing
Stance Phase is shorter or longer and what percentage?
60%
Swing Phase is shorter or longer and what percentage?
40%
Double support cycle occurs in what percentage of walking?
10%
Walking Cycle includes
Heel Strike
Full foot or foot flat
Mid-stance
Heel-off
Toe-off
Acceleration
Mid-swing
Deceleration
Stance phase is from Heel Strike to
Toe-off
Swing Phase is from Toe-off to
Heel Strike
Average walking cadence is
120 steps/min
Each full cycle is how many seconds?
1 second
Double support occurs 10% of time but decreases as speed increases or increases as speed decreases?
Decreases as speed increases
With increasing speed, stance and swing will eventually become
The same length
Running has period of
No support
Note which one has the right order:
A. Heel Strike Mid-Stance Decelaration Acceleration
B. Heel-off Toe-off Mid-Swing Heel Strike
B.
Factors Affecting Normal Gait
Individual Characteristics: Habit, Weight, Posture
Fitness: if fit, gait is springy; if weak or tired, gait may alter
Speed
Gender
Ground Condition/Friction
Footwear
Clothing
Elements of Normal Gait
Proper Alignment: Head erect, Shoulders Level, Trunk Vertical
Reciprocal Arm Swing–arms travel same distance but alternate
Equal Stride Length
Synchronized timing
Body undergoes vertical oscillations that are definite and have even tempo
When one leg is forward, the opposite arm moves forward as well
Trunk and Upper extremity rotate in opposite directions
Stance should be longer than swing
Movement of the Centre of Gravity has the Highest and Lowest Peak when
Highest Peak occurs during Single Limb Support
Lowest Peak occurs during Double Stance
Stance Phase, name 5 descriptions:
Begins at Heel Strike
Leading leg prepares to receive the body weight transferred from the trailing leg
Hip and Knee extensors work to stabilize leg
Hip Abductors and Adductors stabilize the pelvis
Hip Extends until Heel Rises, then Hip and Knee Flex
Swing Phase, describe 4 things during this phase:
After toe-off, trailing leg is lifted from the ground and starts to swing forward
Hip flexors start the swing
Leg swings like pendulum
Swinging leg carries pelvis forward on that side (so pelvis on that side is facing anteromedially). Femur must rotate laterally so toes will point ahead.
Supination is the combination of (“in”)
Inversion of the Calcaneus
Adduction of the Forefoot and
