Hip Flashcards
What are the normal values for hip flexion?
0-120
What are the normal values for hip extension?
0-20
What position may you get less hip extension and why?
Knee flexed because rectus femoris is tight
What is the normal value of abduction?
0-45
What is the normal values of hip adduction?
0-30
What position of the leg will limit hip abduction and why?
Gracilis (a weak knee flexor & hip abductor) is tight when the knee is extended
What are the normal values for IR when in anatomical neutral?
0-55
What are the normal values for ER when in anatomical neutral?
0-55
What is the normal values of IR when the hip is flexed to 90?
0-45
What is the normal values of ER when the hip is flexed to 90?
0-45

(he likes spin)
what are the sagital motions of the pelvis at the hip?
Posterior Tilting & Anterior Tilting
What are the frontal plane motions of the pelvis at the hip?
Hemi-Pelvic Depression & Elevation
OKC IR rotation means what>
Femur moving on fixed pelvis
Femur turned toward pelvis
OKC ER rotation means what?
Femur turned away from pelvis
What are the motions of the pelvis at the hip joint in the transverse plane?
Forward & Backward Rotation
What is OKC of the hip?
All segments move in same direction
What happens in CKC motions?
System strives to keep head & trunk upright
- Lumbar spine & pelvis motion will generally be opposite of that during lumbar pelvic rhythm
what are closed chain hip movements?
Anterior & Posterior Pelvic Tilt
With posterior pelvic tilt does the lumbar become more lordotic or kyphotic?
More lordotic
Lumbar extension
With anterior pelvic tilt does the lumbar spine become more lordotic or kyphotic?
More kyphotic
Lumbar Flexion
What makes up the Osseous structure of the Acetabulum?
