Gait

Question 1

trunk lean

Answer 1

• can be multi-directional

- contralateral side lean to allow for clearance of swing leg

Question 2

cicumduction

Answer 2

Hip abd and flex to clear the foot during gait

Question 3

Vaulting Gait

Answer 3

supporting leg is stance phase goes up on toes to create ground clearance of the swing leg

Question 4
