Gait Initiation And Termination

Question 1

What is gait initiation considered?

Answer 1

Anticipatory postural response

Question 2

What are the 2 phases of gait initiation?

Answer 2

Release phase and unloading phase

Question 3

What happens during the release phase when initiating a step with the right foot?

Answer 3

The COP moves in a posterior direction (accomplished by relaxation of the plantar flexors and activation of right foot dorsiflexors)

Question 4

What happens to the COP during the unloading phase of gait initiation?

Answer 4

Moves forward on the stance foot

Question 5

What happens to the COM during the unloading phase of gait initiation?

Answer 5

Moves forward by contraction of the left plantar flexors

Question 6

What are the 3 phases of gait termination?

Answer 6

Braking

Transition

Stabilization

Question 7

How does the COP move during the braking phase of gait termination?

Answer 7

Forward and lateral on the first leg that stops allowing for COM deceleration

Question 8

What is the braking phase of gait termination influenced by?

Answer 8

Step length (short step length can limit braking ability)

Question 9

Where does the pressure move during the transition phase of gait termination?

Answer 9

Transferred to the leg that first stops and COM moves laterally

Question 10

What happens to speed during the transition phase of gait termination?

Answer 10

Decreases and the leg is brought up to the ground

Question 11

How does COP join COM during the stabilization phase of gait termination?

Answer 11

By completing a short correction posterior and medial
