Rotational Profile

Question 1

5 attributes of ambulation

Answer 1

1. stability in stance
2. swing phase clearance
3. preposition foot for initial contact
4. energy conservation
5. adequate step length

Question 2

1st rocker = ____ rocker at ___ phase

Answer 2

heel
IC & LR

Question 3

2nd rocker = ____ rocker at ___ phase

Answer 3

ankle
midstance

Question 4

3rd rocker = ____ rocker at ___ phase

Answer 4

forefoot
heel rise (terminal stance)

Question 5

4th rocker = ____ rocker at ___ phase

Answer 5

toe, most anterior margin of medial forefoot and great toe
preswing

Question 6

what type of muscles usually cause issues with gait, especially with UMN lesions?

Answer 6

2 joint mm
d/t difficulties with isolated motor control

Question 7

most common swing phase deviation

Answer 7

decreased knee flexion (stiff knee gait)

Question 8

which mm causes stiff knee gait in CP and why?

Answer 8

rectus femoris
d/t only activating as hip flexion

Question 9

3 major categories of foot/ankle gait deviations

Answer 9

excessive DF
excessive PF
bone deformity - malrotation

Question 10

increased PF in stance phase leads to loss of ___ rocker

Answer 10

1st

Question 11

what is the most common stance phase error at ankle?

Answer 11

excessive PF knee extension couple

Question 12

in typical gait, during second rocker, the GFR falls _____ of the knee and ankle causing ____ & ____

Answer 12

in front
knee extension and ankle DF

Question 13

describe the PF knee extension couple

Answer 13

PFs control anterior GFR during midstance by stabilizing the knee then the hip

Question 14

what occurs when the PF knee extension couple is excessive?

Answer 14

excessive PF at IC –> absent 1st rocker
gastroc stretch premature –> premature contraction
leads to knee hyperexten in midstance
