Lumbar test 2 part 2 Flashcards
What are the three components of lumbar stability?
structure, musculature, brain (motor control)
A significant decrease in the capacity of the Stabilizing System of the spine to maintain the intervertebral neutral zones within physiological limits which results in pain and disability defines
clinical instability
Lumbar stability is provided by
the neutral and elastic zone
Dysfunction in one of the stabilizing systems leads to
a. a decrease in the elastic zone
b. an increase in the elastic zone
c. an increase in the neutral zone
d. a decrease in the neutral zone
an increase in the neutral zone
This is described as a fracture on one side or both of the pars interarticularis
a. osteoporosis
b. spondylolisthesis
c. spondylolysis
d. disc lesion
spondylolysis
What structures can be limited due to lumbar instability?
ligamentous laxity osteoporosis spondylolysis spondylolisthesis chronic disc lesions SIJ dysfunction
Which motion irritates osteoporosis, spondylolysis, spondylolisthesis?
a. flexion
b. extension
c. side bending
d. rotation
extension
Fracture but no slippage
a. osteoporosis
b. spondylolisthesis
c. spondylolysis
d. disc lesion
spondylolysis
Spondylolysis is rare (true/false)
false
This is classified based on the ratio of the overhanging part of the superior vertebral body to anterior-posterior length of the adjacent inferior vertebral body
a. osteoporosis
b. spondylolisthesis
c. spondylolysis
d. disc lesion
spondylolisthesis
a slippage of 0-25% is classified as
a. grade IV
b. grade I
c. grade II
d. grade V
grade I
a slippage of 26-50% is classified as
a. grade IV
b. grade I
c. grade II
d. grade V
grade II
a slippage of 51-75% is classified as
a. grade IV
b. grade III
c. grade II
d. grade V
grade III
a slippage of 76-100% is classified as
a. grade IV
b. grade III
c. grade II
d. grade V
grade IV
a slippage of >100% is classified as
a. grade IV
b. grade III
c. grade II
d. grade V
grade V
The most common slippage is at
a. L1/L2
b. L2/L3
c. L4/L5
d. L3/L4
L4/L5
Compression and/or stretching of the inflamed neural elements causes
a. increased disc motion
b. decreased intervertebral motion
c. increased laxity
d. decreased stability
e. increased intervertebral motion
increased intervertebral motion
Abnormal deformations of ligaments, joint capsules, annular fibers, and end-plates causes
a. increased disc motion
b. decreased intervertebral motion
c. increased laxity
d. decreased stability
e. increased intervertebral motion
increased intervertebral motion
Ligaments, joint capsules, annular fibers, and end plates do not have nociceptors (true/false)
false
What changes happen to the disc with aging?
loss of fluids and proteoglycans, matrix and bone changes, disc space height is lost
Chronic disc lesion is associated with an
increased micro “shear” of the intervertebral level
An increase in fear causes more problems with _
a. motor control
b. memory
c. sequencing
d. firing of TA
motor control
Which treatment is best to improve inhibited muscles?
a. mobilization
b. manual therapy
c. stabilization
d. modalities
manual therapy
What could be the muscle/motor cause of poor lumbar stability?
altered sequencing
endurance
fatigue
inhibition
