Gait 2

Question 1

Knee
At heel contact

Answer 1

Knee flexion (5°)
Continues to flex an additional 10-15° during the initial 15% of the GC
Controlled by eccentric action of the quadriceps

Question 2

Knee
About heel off (30-40% of GC)

Answer 2

approaches near full extnesion

Question 3

Knee
Toe off (60% of GC)

Answer 3

Knee flexion (35°)

Question 4

Knee
Beginning of mid swing (75% of GC)

Answer 4

Maximum knee flexion of (60°)

Question 5

Knee
Mid and late swing

Answer 5

The knee extends to just short of full extension before starting to flex in heel contact

Question 6

Knee
For normal gait: full extension to approximately

Answer 6

60° of flexion is required

Question 7

Knee flexion contracture

Answer 7

Functionally shorter limb

Excessive trunk movement  increasing the metabolic demands of walking

Increases the muscular demand on the knee extensors

Question 8

Lack of sufficient knee flexion

Answer 8

Lack of toe clearance in swing
phase

Hip may flex excessively to compensate

Question 9

If the knee is immobilized in full extension

Answer 9

Hip hiking or circumduction may occur
