Rotational Profile Flashcards
5 attributes of ambulation
- stability in stance
- swing phase clearance
- preposition foot for initial contact
- energy conservation
- adequate step length
1st rocker = ____ rocker at ___ phase
heel
IC & LR
2nd rocker = ____ rocker at ___ phase
ankle
midstance
3rd rocker = ____ rocker at ___ phase
forefoot
heel rise (terminal stance)
4th rocker = ____ rocker at ___ phase
toe, most anterior margin of medial forefoot and great toe
preswing
what type of muscles usually cause issues with gait, especially with UMN lesions?
2 joint mm
d/t difficulties with isolated motor control
most common swing phase deviation
decreased knee flexion (stiff knee gait)
which mm causes stiff knee gait in CP and why?
rectus femoris
d/t only activating as hip flexion
3 major categories of foot/ankle gait deviations
excessive DF
excessive PF
bone deformity - malrotation
increased PF in stance phase leads to loss of ___ rocker
1st
what is the most common stance phase error at ankle?
excessive PF knee extension couple
in typical gait, during second rocker, the GFR falls _____ of the knee and ankle causing ____ & ____
in front
knee extension and ankle DF
describe the PF knee extension couple
PFs control anterior GFR during midstance by stabilizing the knee then the hip
what occurs when the PF knee extension couple is excessive?
excessive PF at IC –> absent 1st rocker
gastroc stretch premature –> premature contraction
leads to knee hyperexten in midstance
what are the 6 components of the rotational profile?
foot progression angle
medial & lateral hip rotation

anteversion:
_____ Q-angle

external tibial torsion
retroversion:
_____ Q-angle
_____ tibial torsion
decreased Q-angle (<15 deg)
internal tibial torsion
why does miserable malignment occur in CP (GMFCS I or II)?
compensation for hemiplegia CP due to pelvic retraction in attempt to correct in-toeing
common sign of miserable malignment
fall while running
in miserable malalignment, the tibia ____ and femur ____
tibia ER
femur IR
squinting patella is a ___ plane deviation
transverse
