(6 cards)
1
Q
Movements of the lumbar spine
A
flexion
extension
rotation
lateral flexion
2
Q
range of movement
A
greater range of flexion than extension
more movement in lower segments L4 L5 S1
flexion- 50-60 degrees
extension- 30 degrees
3
Q
side flexion
A
25 degree
coupled with rotation
4
Q
rotation
A
1 degree at each segment
less rotation at L5-S1
mean rotation is 8-12
rotation is limited by orientation of the facet joint
5
Q
coupling of movement
A
the rotation or translation of a vertebral body along one axis that is consistently associated with the main rotation or translation about another axis
6
Q

A
decreases with age
pathology
