Lumbopelvic Flashcards
What are the 4 primary functions of the pelvis?
- Bear weight
- Transfer loads from the axial skeleton to append skeleton
- limited mobility
- ->more efficient transfer of loads
- muscle attachments
Do males or females have more prominent bony features on the pelvis?
Males
Wide oval pelvic inlet
or
Narrow heart shaped inlet
Which is male and which is female?
First female
second male
Do males or females have a narrow distance between ASIS and ischial tuberosities?
Males
A lateral facing acetabulum and an anterior facing acetabulum. Which belongs to female and which to male?
Male-lateral facing
Female-anterior facing
Whose pubic arch is wider a males or a females?
Females (child birth)
Males have a smaller base of support in sitting.
T or F
True
If you are in a R unilateral stance, What are the 2 primary muscles that are acting to keep the pelvis level?
- Glut med acting to pull into R lat tilt
- Left Lumbar erector spinae to also pull pelvis into lat tilt 1
Ipsilateral lumbopelvic rhythm serves what purpose?
To increase overall trunk motion for function
What is the correct order of movement with the lumbar spine and pelvis with flexion/extension?
Flexion- lumbar to pelvis
Extension-pelvis to lumbar
LBP patients tend to differ in what way in lumbopelvic movement?
Tend to do it backwards
How would you perform the Gower sign?
Ask patient to bend forward as far as they can and then return to standing
If they have to “thigh climb” then the test is positive
What is the instability catch sign?
Patient asked to bend forward as far as they can go and return to standing
If they cannot return due to sudden painful catch in low back then its positive
Thought to indicate spinal instability
What are the 3 aberrant movement patterns (sagittal)?
- gower sign
- instability catch
- lumbopelvic rhythm
What is the only aberrant movement pattern with good interrater reliability?
Gower sign
