Exam 3 - Lower Extremity Flashcards
(162 cards)
What is the joint commonly referred to in the hip?
iliofemoral joint
How many degrees of freedom does the iliofemoral joint of the hip have?
3 df
What are the motions occurring at the iliofemoral joint?
flexion/extension, abduction/adduction, internal/external rotation
In the hip, what ROM test has testing position been shown to have the greatest effect on the measurement?
lateral/external rotation of the hip
(significantly lower in seated position compared to prone)
What has been shown to be a direct determinant of hip flexion ROM?
body mass index
What are the benefits of testing the hip ROM in a seated position?
locks out the pelvis, allows for isolation of hip motion
In what plane and what axis does hip flexion occur in?
sagittal, medial-lateal
What is mean hip flexion range according to AAOS?
120 degrees
What is the testing position for measuring hip flexion ROM?
supine, knees extended, hips in 0 degrees of ab/adduction and neutral rotation
what is the normal end feel of hip flexion?
usually soft
why do you want to eliminate the patient from pulling their knee toward them when measuring knee flexion ROM?
this creates passive range of motion and is not accurate
eliminates passive insufficiency
where are the goniometer alignments for measuring hip flexion ROM?
axis - over lateral aspect of greater trochanter
stationary arm - along lateral midline of pelvis
moving arm - along lateral midline of femur toward lateral epicondyle
in what plane and what axis does hip extension occur in?
sagittal, medial-lateral
what is the mean hip extension ROM according to AAOS?
20 degrees
what is the testing position for measuring hip extension ROM?
prone, both knees extended, hip in 0 degrees of ab/add/rotation
no pillow under head, but can place under abdomen if more comfortable
what is the normal end feel for hip extension?
firm
what are the goniometer alignments for measuring hip extension ROM?
axis - over lateral aspect of greater trochanter
stationary arm - along lateral midline of pelvis
moving arm - along lateral midline of femur toward lateral epicondyle
In what plane and what axis does hip abduction occur in?
frontal, anterior-posterior
what mean values do the AAOS and AMA report for mean hip abduction ROM?
AAOS - not available
AMA - 40 degrees
what is the testing position for measuring hip abduction ROM?
supine, hip in 0 degrees of flexion/extension/rotation and knee is extended, foot is neutral
what is the normal end feel for hip abduction?
firm
what is the goniometer alignment for measuring hip abduction ROM?
axis - over the ASIS of tested side
stationary arm - imaginary horizontal line from one ASIS to other
moving arm - along midline of femur toward patella
in what plane and what axis does hip adduction occur in?
frontal, anterior-posterior
what is the mean hip adduction ROM according to AAOS?
20 degrees
