Human Gait Cycle Flashcards
locomotion
ability to move from one place to another by generating complex sequence of muscle activations that are stereotypical, repetitive and adaptable
Human Gait
Complex series of joint rotations that produce a smooth forward progression of the body’s center of mass (OCM)
entire stride
heel strike to heel strike of the same leg; encompasses both stance phase and swing phase and left and right step
What is happening during the Stance Phase?
weight acceptance
single limb support
progression over the supporting foot
preparation for swing
What is happening during the Swing phase?
Limb advancement
toe clearance
forward reach
preparation for initial contact
stride length
distance between two successive heel contacts of the same foot
step length
distance between heel contacts of the two different feets
step width
lateral distance between the heel centers of two consecutive foot contacts
foot angle
the amount of “toe out”; is the angle between the direction of progression and the long axis of the foot
Distanced Covered Value
80 m (260ft) on 1 min
Stride length value
144 cm (4.5ft)
Step length value
72 cm (28 inches)
Step width value
7-9 cm (3 inches)
foot angle value
7 degrees seeing three smaller toes from behind
cadence (step rate)
number of steps per minute
step time
Time for a step
stride time
time for a full gait cycle
stance time
What is the time spent in stance phase of gait?
gait speed value
1.3 m/sec or 3 mph
Distance value
80 meters or 260 feet/minute
Where is the Center of Mass positioned?
Anterior to the S2 segment in the body and moves vertically and laterally during gait
how much do we move upwards?
5 cm
how much do we move downwards?
2 cm
How much do we sway side to side?
1 cm
