Human Gait Cycle

Question 1

locomotion

Answer 1

ability to move from one place to another by generating complex sequence of muscle activations that are stereotypical, repetitive and adaptable

Question 2

Human Gait

Answer 2

Complex series of joint rotations that produce a smooth forward progression of the body’s center of mass (OCM)

Question 3

entire stride

Answer 3

heel strike to heel strike of the same leg; encompasses both stance phase and swing phase and left and right step

Question 4

What is happening during the Stance Phase?

Answer 4

weight acceptance
single limb support
progression over the supporting foot
preparation for swing

Question 5

What is happening during the Swing phase?

Answer 5

Limb advancement
toe clearance
forward reach
preparation for initial contact

Question 6

stride length

Answer 6

distance between two successive heel contacts of the same foot

Question 7

step length

Answer 7

distance between heel contacts of the two different feets

Question 8

step width

Answer 8

lateral distance between the heel centers of two consecutive foot contacts
