Gait Analysis FINAL

Question 1

Answer 23

• extension

- plantar fascia

Question 24

when does late stance end

Answer 24

when the contralateral foot contacts the ground.

Answer 25

Begins at contralateral initial contact & ends at toe off.

Question 26

when does swing phase being and end

Answer 26

begins at toe off | - occurs until foot has completed the gait cycle by making contact with the ground again
