Importance of 2 Factors to Development
of LBP
(repeated movements & prolonged postures)
• Results in adoption of movement & alignment
strategies in lumbar spine in a specific direction(s)
•
the most flexible segment moves
• More frequently
• Through greater range of motion than optimal
• Can compensate for the restricted range of adjoining
segments

LBP is a mechanical disorder associated with the
progressive characteristics of degenerative joint
disease (the march to stenosis
stenosis))
Repeated movements of the spine in specific
direction(s)
Overt trunk movements, e.g., forward bending & return
Induced movements via limbs, e.g,
e.g, lumbopelvic rotation with hip
rotation
Prolonged postures of the spine associated
with specific direction(s)
Importance of 2 Factors to Development
of LBP
(repeated movements & prolonged postures)
• Strategies are generalized across person’s
everyday activities
• Continued use of strategies contributes to changes
in movement system elements
e.g., changes in muscle length &/or stiffness
e.g., changes in motor recruitment patterns

Key Examination Findings
Signs
Key Examination Findings
– Lumbar rotation impairments across several
positions
Rotation
= rotation; side bending; lateral shift
– Impairments
Alignment
of the lumbar spine, e.g., asymmetry
in standing or quadruped
Movement of the lumbar spine
– e.g., asymmetric side bending
– e.g., lumbopelvic rotation with hip rotation
Alignment:
Iliac Crest High on Right (SB)
Symptoms
– sxs often associated with lumbar rotation
signs, particularly if in weight bearing
position
e.g., side bending – asymmetric & sxs
– sxs may also with both flexion and
extension movements of the lumbar spine
e.g., sitting in flexion & sitting in extension
e.g., forward bending & return

Primary Rotation
Acute Pain (often)
– The rotation is causing the symptoms
– Pt presents with a shift
Most often has pain at rest, particularly when
weight bearing
Has notable asymmetry in lumbar region
May have symptoms as rest or on verge of sxs
Symptoms with sidebending and rotation in
standing
– Correction of the rotation reduces the
symptoms
– Dx:
Dx: typically FlexionFlexion-Rotation
Rotation-Related Alignment Impairment
Primary
Rotation Classifications:
Primary
Quadruped: rocking back, the rotation in the
lumbar spine increases
– Has symptoms as lumbar region goes from
flexion toward neutral (extension)
– Decreases in flexion and Sxs as repeats the
rocking backward. (slight manual correction)
Asymmetry corrected with repeated rocking
Remain susceptible to recurrent episodes of
rotation of offending joints (rotation(rotation-ext/flex)

Rotation-Related Alignment Impairment
Asymmetry of thoracolumbar regions
No symptoms at rest even in weight bearing
The rotated region/joints prevent motion at
these joints resulting in excessive motion at the
joints below the rotated regions
– Disc degeneration in joints with excessive motion
The rotated joints do not cause pain

Treatment Guidelines
Modify daily work, leisure, and self care
activities.
– Change direction
direction--specific movement &
alignment strategies during regular activities.
Change
regular stimulus that is proposed to
be related to LBP & adaptations contributing
to LBP.
– Decreased stress on tissue (short
(short--term effects)
– Changes stimulus contributing to passive or
active adaptations (long(long-term effects)
Treatment Guidelines
Prescribe exercise/positioning to
address contributing factors (changes
in movement system elements).
– Motor control
Retrain
in appropriate movement strategy
– Redistribute motion
