6 Determinants of Gait

Question 1

6 determinants of gait

Answer 1

1. Pelvic Rotation2. Pelvic Tilt3. Lateral Pelvic Motion4. Knee Flexion (Heel strike to midstance)5. Knee/Foot and ankle motion

Question 2

Pelvic Rotation

Answer 2

4-5 degrees about the vertical axis results in Increased stride lengthDecrease lower limit of C0G displacement which occurs during double support

Question 3

Pelvic Tilt

Answer 3

5 degrees about the frontal axis (hip adduction)decreases upper limit of CoG displacement which occurs during mid-stance

Question 4

Lateral Pelvic Motion

Answer 4

1 inch lateral displacementAll that is required to maintain CoG over the stance limb

Question 5

Knee Flexion (Heel strike to midstance)

Answer 5

15-20 degrees by foot flat which aids in shock absorption and decreases upper limit CoG displacement

Question 6

Knee/Foot and ankle motion

Answer 6

Act to attenuate displacement of CoG throughout the gait cycle
