Gait

Question 1

Phases

Answer 1

Stance Phase (60%)
Swing Phase (40%)

Question 2

Events

Answer 2

IC
TO
HO
FA
TV

Question 3

What event happens at end of stance phase and at beginning of swing phase

Answer 3

Toe off (R)

Question 4

Stance phase - 3 periods

Answer 4

Double support - single support (R) - double support
Double = 10% each
Single = 40%

Question 5

Swing phase - 1 period

Answer 5

Single support (40%) 
Left

Question 6

During initial double support what is happening

Answer 6

Transferring weight
“Loading Response” (0-10%)
Weight of the leg in question is getting the body weight

Question 7

Single support phase can be broken into

Answer 7

Mid stance and terminal stance

Question 8

Mid stance

Answer 8

foot is flat on the ground
ends with HO (R)
10-30%

Question 9

Terminal Stance

Answer 9

30-50%
Ends with L IC
Starts with R HO

Question 10

Last double support

Answer 10

Preswing - before swing starts
50-60%
Ends with R TO

Question 11

Stance Phase broken into 4 periods

Answer 11

Loading response 10
Mid Stance 20
Terminal Stance 20
Preswing 10

Question 12

Swing phase starts with

Answer 12

TO (R) of ipsilateral leg

Question 13

Swing phase broken into 3 periods

Answer 13

Initial Swing
Mid Swing
Terminal Swing

Question 14

Initial Swing

Answer 14

Ends with FA (when ankles cross each other)

13%

Question 15

Mid Swing

Answer 15

FA until TV
Tibia becomes vertical
14%

Question 16

Terminal Swing

Answer 16

TV until IC (R)

13%

Question 17

High heels - which period during swing would be short

Answer 17

Terminal Swing

base of support is very small - HC is very minimal - usually come with foot flat

Question 18

Over a gait cycle, how long in double support

Answer 18

20%

Question 19

Over gait cycle, how long in single support

Answer 19

80%

Question 20

Pelvic Angular Motions with Gait and their planes

Answer 20

Pelvic Drop = Frontal (Obliquity) 7 deg
Tilt = Sagittal 4 deg
Rotation = Transverse 10 deg

Question 21

Frontal - Obliquity

Answer 21

The support side is higher than the swing side due to leverage system
COG is medial to hip joint
Contralateral drop = positive
7 degrees

Question 22

Sagittal

Answer 22

Pelvic Tilt
Repeats itself in single gait cycle
post - ant - post - ant
Ant tilt = positive
4 degrees
IC = post tilt
Ant tilt = pick leg up and starts to swing forward

Question 23

Transverse

Answer 23

Rotation
10 degrees
Ipsilateral hemipelvis forward = positive - rotation to the opposite side
RHC to RHC - one cycle - rotate left to rotate left
