Q

What does horizontal plane pelvic rotation do?

A
  • Functionally lengthens the LE in DLS
  • Hip Flex/Ext angle required is reduced
  • Downward displacement of COG is reduced

Q

What happens during Pelvic Obliquity (frontal plane pelvic rotation)?

A
  • The contralateral pelvis drops during midstance (mid swing of the dropped limb), which minimizes the net elevation of the COG

Q

What happens to the displacement of COG when the knee is flexed during mid stance?

A

Reduces the function length of LE, reducing the upward displacement of COG

Foot- slightly pronated, starts to reverse

19
Q

A

Trunk- vertical Position begins to lower
Pelvis- rotate back (Lead Limb)
Hip- extended 10-20 degrees, reaches peak

21
Q

A 
Trunk- Gains height
Pelvis- rotates forward (Lead Limb)
Hip- Flexed 15 degrees
Knee- Flexed 60-70 degrees 
Ankle- PF to 25 degrees after toe off
22
Q

What are the angle ranges for the Pelvis, Hip, Knee, Ankle, and Foot at Mid Swing?

A 
Trunk- Highest vertical position
Pelvis- Neutral (Lead Limb)
Hip- Flexed 25-30 degrees
Knee- Extends 25 degrees

23
Q

What are the angle ranges for the Pelvis, Hip, Knee, Ankle, and Foot at Terminal Swing?

A 
Trunk- lowering vertical position
Pelvis- Rotates forward(Lead Limb)
Hip- Flexed 25-30 degrees
Knee- Approaches full extension
Ankle- neutral
Foot- slightly supinated
24
Q

What happens with ankle mechanism?

A

Heel sticks out behind the ankle, lengthening the leg, reducing the downward displacement of COG

25
Q

What happens with foot mechanism?

A

PF of the foot lengthens the leg, reducing the downward displacement of COG

26
Q

What are the benefits of a narrow walking base?

A

Less energy is used shifting the COG to the right and left.

27
Q

Describe IC until the age of 2.

A

IC is made with the flat foot

28
Q

Describe stance and swing phase of a child until the age of 2.

A
  • Little stance phase flexion

- Whole leg is externally rotated in swing phase

29
Q

Describe walking base and arm swing of a child until the age of 4.

A
  • Wider walking base

- No reciprocal arm swing
