Lumbar Rotation Lumbar Rotation as a Key Factor in Low Back Pain: Anatomy Kinesiology Role in degenerative disc disease Clinical and Research Evidence Shirley Sahrmann, PT, PhD, FAPTA Nancy Bloom, PT, DPT, MSOT Barbara J Norton, PT, PhD, FAPTA Presented by Shirley Sahrmann, PT, PhD, FAPTA Key Concepts for Diagnostic Categories Lumbar Rotation Syndromes – Accelerated by the following 2 factors Presented by: Nancy Bloom, PT, DPT, MSOT 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 Copyright: S. Sahrmann & Associates 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 1 Low Back Movement System Impairment Diagnoses Primary Test & Secondary Test Trunk Movement Named for movement direction or alignment most consistently causing symptoms – Flexion, Extension, Rotation, Flexion Flexion--rotation; Extension--rotation Extension Treatment – prevent movement in the painful direction – Correct the tissue adaptations that are contributing to the segments’ directional susceptibility to movement (interrupt the vicious cycle) Patient-Preferred Movement Modified Movement Symptoms Monitored & Compared Primary & Secondary Test Trunk Alignment Patient-Preferred Alignment Primary: Patient Preferred Secondary: Modified Support above iliac crest Modified Alignment Symptoms Monitored & Compared + Pain - Pain 5 Syndromes Lumbar Rotation* Lumbar Rotation with Extension* Lumbar Rotation with Flexion Lumbar Extension* Lumbar Flexion Lumbar Rotation Syndrome * Most prevalent in sample of people with primarily subacute/chronic, subacute /chronic, recurrent LBP (Van Dillen et al., 2003) Judgment based on consistency of responses across examination (Norton et al, 2004) Copyright: S. Sahrmann & Associates 2 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 Lumbar Rotation Syndrome - Example Demographics: 24 year old P.T. student Female Prolonged posture: • Carrying tray with left hand Complaint: • LBP with sitting • Specifically – class • Sitting in class leaning to R>L Occupation: • Student fulltime • Waitress parttime RotationRotation -Related Movement Impairment Repeated movement: Repeated shifting in class Student with Low Back Pain, Unable to Sit in Class Asymmetric side bending Pelvic shift to left; Trunk shift to right Trunk shift to left Copyright: S. Sahrmann & Associates 3 2 Types of Rotation Classification 1 Month Later Primary Rotation Secondary Rotation No Pain Able to Sit in Class Has to be Careful Primary Rotation 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) LBP in standing. Lumbar side bend to right with shift of trunk to left. Copyright: S. Sahrmann & Associates 4 Flexion--rotation during Flexion rocking backward Improved lumbopelvic alignment Hips stiffer than lumbar spine Acute Episode of LBP – Primary Rotation Treatment Effect Before Day 1 After quadruped rocking Day 5 Copyright: S. Sahrmann & Associates Day 1 Day 5 5 Lumbar rotation (clockwise/L side prominent) with Rocking Back in Quadruped Natural standing Left foot resting on phonebook Rotation Classification Secondary Correction for Treatment Day 13 – taped 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 Asymmetry of lumbar spine region Copyright: S. Sahrmann & Associates 6 Rotation-Related Alignment Impairment Rotation-Related Movement Impairment Asymmetry of lumbar spine region Asymmetric rotation Asymmetrical Lateral Lumbar Flexion Unable to side bend to left because spine rotated left vertebrae cannot rotate right Stiffness of left hypertrophied left paraspinal muscles limit side bending to right Primary & Secondary Test Limb Movement Copyright: S. Sahrmann & Associates Induced Spinal Movement via Limb Movement Hip abduction/LR induces lumbar rotation Lumbar rotation - Hip abd/add 7 Key Examination Findings Standing – Asymmetry in lumbar spine region – Asymmetric side bending; movement at 1 or a few segments of lumbar spine Lumbar Rotation with Extension Syndrome Sitting – Lumbar rotation with knee extension (asymmetric) – Sxs with knee extension; Modified knee extension sxs Side lying – Sxs Lumbar Rotation with Extension Syndrome - Example Demographics: 62 y/o female 5’ 1/2” tall Complaints: LBP with sitting at work Occupation: Administrative assistant Prolonged posture: • Sits on edge of chair in lumbar extension & thoracic flexion Repeated movements: • Arm flexion at desk in side lying (asymmetric); Modified side lying sxs Patient-Preferred Movement - Forward Bend Thoracic flexion Lumbar spine straight Hip flexion 80 degrees • Rotates to the right Patient-Preferred Movement Modified Movement Lordosis & kyphosis with arm movement Less lordosis & kyphosis with arm movement Copyright: S.

Will stretching the hamstrings resolve impairment? Secondary Test: Note decrease in knee extension ROM What muscles does she have to use to do this? Preferred Test Patient-Preferred Movement Secondary Test Modified Movement Symptoms Monitored & Compared Hip Flexor Length Test – Relative flexibility/stiffness of hip flexors vs lumbar spine – Asymmetry between (R) and (L) sides in TFL TFL--ITB stiffness & shortness – Contributes to rotation impairment Copyright: S.

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 Clinical Research Supporting Rotation Syndromes Presented by: Barbara J Norton, PT, PhD, FAPTA Decreasing Increasing movement in lumbar spine movement in other segments Copyright: S.
