Question 7

GAIT TERMINOLOGY: Cadence

Answer 7

Step Rate

Question 8

Answer 8

Time for a full gait cycle

Question 9

GAIT TERMINOLOGY: Step Length

Answer 9

Distance b/w initial contacts of 2 different feet

Question 10

GAIT TERMINOLOGY: Stride Length

Answer 10

Distance b/w initial contacts of the same foot (aka: gait cycle)

Question 11

Step Width

Answer 11

Lateral distance b/w heel centers of 2 consecutive foot contacts.

Question 12

Walking Speed

Answer 12

Time taken to cover a certain distance

Question 13

Subdivisions of Gait (10)

Answer 13

Initial Contact/Heel Strike
Loading Phase/Foot Flat
Mid-stance
Terminal Swing/Heel off
Pre-swing/Toe off
Initial Swing/Acceleration
Mid-Swing
Terminal Swing/Deceleration

Question 14

Periods of double limb support

Answer 14

Initial contact through loading response
End of Terminal Stance through Pre-Swing

Question 15

ROM Sagittal: Hip
Flexion - extension

Answer 15

30° flexion - 20° extension

Question 16

ROm Sagittal: Knee

Answer 16

60° flexion - 0° extension

Question 17

ROM Sagittal: Ankle

Answer 17

10° dorsiflexion - 20° plantarflexion

Question 18

Role of Hip Abductors

Answer 18

They Control the dip of contralateral pelvis during its swing.
This helps prevent Trendelenburg gait sign.

Question 19

Role of Hip ADductors

Answer 19

They are most at initial contact and toe off.
During initial contact, they work together with the extensors to stabilize the hip complex and help with hip extension. (Phase 1)
Right after toe off, they help with hip flexion. (Phase 5)

Question 20

Subtalar Joint Actions: Pronation
Talus:
Calaneus:
Tibia:

Answer 20

Talus: Adduction, Plantarflexion
Calcaneus: Eversion
Tibia; Internal Rotation

Question 21

Subtalar Joint Actions: Supination
Talus:
Calcaneus:
Tibia:

Answer 21

Talus: Abduction, dorsiflexion
Calcaneus: Inversion
Tibia: External Rotation
