Rotational Profile Lab Flashcards
What are the 6 measures of the rotational profile
foot progression angle
medial and lateral hip rotation
ryders test of anteversion
thigh-foot angle
transmalleolar axis-thigh angle
foot configuration
Where do you need to draw lines on pt for the rotational profile?
Mid-thigh
middle of foot
1 dot on medial and lateral mal
what is the standard of error for goni
5 degrees
A pt with an IR bias will likely have __________
a pt will ER bias will likely have _________
IR bias- anteversion
ER bias- retroversion
what is considered normal anteversion for a newborn
40 of IR
what is considered a normal transmalleolar axis in a newborn
0 (and as you get older it increases into external rotation)
how does anteversion progress as a newborn grows
40 IR (newborn) -> 23 IR (5 year old) -> 20 IR (8 year old) -> 10-15 (15 years old)
how does the transmalleolar angle progress as a newborn grows
0 degrees -> 10-15 ER (2 years old) -> 20-30 ER (5 years old)
what is the normal thigh-foot angle in a newborn?
5-10 IR
What is normal thigh-foot angle for a 5 year old
10 ER
how does thigh-foot angle progress as a newborn ages
5-10IR(newborn) -> 10 ER (5 years) -> 12-30 ER (15 years)
T or F: in the rotational profile one angle is predictive of the angle below it
F
What rotations comprise of miserable mal-alignment
excessive anteversion + excessive ER with thigh-foot angle
what 2 parts of the rotational profile screen for miserable mal-alignment
ryders test + thigh-foot angle or transmalleolar -thigh angle
Ryder test norms:
10-15 IR = normal
15+ anteversion
under 10: retroversion
how do you measure foot configuration?
Goni the midline of the bottom of heel compared to the 2nd toe
how to measure transmalleolar axis?
goni the line between the malleoli and perpendicular to that AND the midline of the thigh
how to measure thigh foot angle?
goni the line bisecting the bottom of the boot and the midline of the thigh
What could it mean if trans-malleolar angle is normal but thigh-foot angle is abnormal
potential metatarsus abductus
What is the normal foot progression angle?
0-10 of ER (IR is never normal!)
