  1. Physical Therapy Approachto Low Back Pain - Lumbar Stabilization Stacey Franz, DO, MSPT Medical Director, NorthEast Spine & Sports Medicine

  2. Disclosures • I have no relevant financial disclosures

  3. How our core supplies stability • Promote muscle stiffness to control segmental translation • segmental stability is dependent on recruitment of the deep local stability muscles • Anticipatory recruitment prior to functional loading provides protective stiffness • Proximal stability for movement of extremities • Generates force to control, limit range of motion • Concentric action through the range of motion • isometric action to hold position • Eccentrically control the return

  4. Anatomy of the Core – Lumbar Muscles • Muscles • Transversospinalis group • Rotatores, Interspinales, Intertransversarii, Multifidi • Erector spinae • Iliocostalis, Longissimus, Spinalis • Latissmusdorsi • Quadratuslumborus • Physiology • Poor mechanical contribution to movement production • Primarily Type I fibers = segmental stabilization • Optimal for proprioceptive feedback *Multifidi most important muscle in this group*

  5. Anatomy of the Core – Abdominal Muscles • Muscles • Transversus abdominus • External obliques • Internal obliques • Physiology • Provide sagittal, frontal & transverse plane stabilization • Transversus abdominus • increases intra-abdominal pressure = dynamic stab. against rotational, translational stress • Necessary for anticipatory control • Activates prior to movement of the limbs or trunk to increase stability of the spine, prevent unwanted trunk movement • Activity contributes to spinal control • Attach to thoracolumbar fascia = add tension w/ contraction Cresswell 1994, Cresswell 1992, Hodges 1999

  6. Anatomy of the Core – Hip Muscles • Muscles • Psoas • Glut medius • Glut maximus • Hamstrings • Physiology • Psoas tightness can be problematic • can lead to reciprocal inhibition of glut maximus, multifidus, erector spinae, internal oblique, TA • lead to Extensor mechanism dysfunction • increase shear and compressive forces at L4-L5 junction

  7. Anatomy of the Core – Hip Muscles (continued) • Physiology • Glut medius weakness • increase frontal and transversus plane stress at patella-femoral joint and tibiofemoraljoint • synergistic dominance of TFL & quadratus lumborum • Glut maximus • Decreased activity can lead to pelvic instability, decreased neuromuscular control

  8. What happens to the core when we have low back pain? • Inefficient muscular stabilization • Pain leads to inhibition of muscle control • Motor control deficit associated with delayed timing or recruitment deficiency • Transversus abdominus shows decreased ability to contract in patients with recurrent low back pain • Impairs our anticipatory control • Impairs our spinal control Stokes & Young 1984, Hides et al. 1994, Hodges & Richardson 1996, Hodges 1997, Ferreira 2004, Cresswell 1992, Hodges 1999

  9. What happens to the core when we have low back pain? (continued) • Weakness and muscle fatigue • Multifidi atrophy in patients with chronic LBP • In unilateral acute/ subacute LBP, there is 31% side to side difference with atrophy of affected side - 3% in controls • Decreased endurance of extensors • Abnormal flexor to extensor strength ratios • Decrease in muscle integrity results in lack of control of segmental translation Richardson 1999, Jorgensen 1987, Ebenbichler 2001, McGill 2002, Siolie2001

  10. What happens to the core when we have low back pain? (continued) • Decreased spine proprioception • Multifidi atrophy in those with LBP • Proprioception partly from multifidi • Difficulty repositioning into neutral spine posture • Loss of control of neutral joint position • Postural control shown to be altered in patients with chronic LBP • Single leg stance balance • Postural stability tests • Unexpected balance challenges • Trunk perturbation Bogduk1997, Hides 2004, O’Sullivan 2003, Ebenbichler 2001, Mok 2004, Wilder 1996

  11. How Does Core Stabilization help Low Back Pain • Multifidi activation improves pain in acute & chronic LBP • Multifidi dysfunction does not correct automatically when pain resolves but specific training can correct dysfunction • Segmental stabilization training with co-contraction of Transversus abdominus and Multifidi • Abdominal bracing training stiffens the spine and improves stability • Exercise, in general, beneficial for low back • Slows degenerative conditions • Enhances nutritional benefits to spine Hides 1996, O’Sullivan 1997, Grenier 2007

  12. Lumbar Stabilization Concepts • What does it entail: • Recruitment of proximal trunk & girdle muscles • Ability of agonists, antagonists, synergists, to work efficiently & interdependently • Facilitates balanced muscular functioning of the entire kinetic chain • How does it translate functionally: • Enhances neuromuscular control/ efficiency throughout the kinetic chain • Optimizes postural alignment & dynamic postural control • Affect arthrokinematics around lumbo-pelvic-hip complex • Promote dynamic strength

  13. Lumbar Stab. Concepts (continued) • Neutral vs. Dynamic Stabilization • “Neutral spine stabilization” introduced in 1980s • Position of comfort where muscular support reduces stress on painful structures • “Dynamic stabilization” introduced in 1990s • more functional; multi-planar requiring acceleration & stabilization • interest increased after Joe Montana returns to football after lumbar spine surgery

  14. Assessment of the Core • Prone instability test • Prone extension endurance test • Side bridge endurance test (quadratus lumborum endurance strength) • Straight leg raise • Pelvic bridging • Leg lowering test (lower abdominal strength) • Trunk curl • Hip external rotation strength • Modified Trendelenburg test (single leg squat with observation in frontal plane) • Single leg squat in sagittal plane • Single leg squat in transverse plane Akuthota et al 2008, Hicks 2005

  15. Program Prescription • Be mindful of pain generators • Flexion vs. Extension vs. Neutral program • Exercises that span the spectrum of muscle contraction • Concentric (force production) • Eccentric (force reduction) • Isometric (dynamic stabilization) • Exercises that span body positioning • Supine • Prone • Quadruped • Sitting

  16. Program Prescription (continued) • Progression should include additional reps rather than increasing duration of hold • Can perform 30 reps with 8 sec hold • Should challenge the patient by progression through function continuum • Slow to fast • Simple to complex • Low force to high force • Eyes open to eyes closed • Static to dynamic • Quality, not Quantity • Poor technique and neuromuscular control results in poor motor patterns & stabilization Akuthota 2008

  17. Level 1- Stabilization Pelvic tilts • Supine • Diaphragmatic breathing • Abdominal bracing • Pelvic tilts • Arm lift • Leg lifts • Opposite arm lift/ leg lift • Marching • Bridging • w/ arms at sides • w/ arms at 90 degrees • w/ marching Bridging (http://www.netfit.co.uk)
