Presentation Transcript

  1. The Spine

  2. Structure and Function of the Spine • http://www.delawarebackpain.com/patient%20information • http://www.emory.edu/ANATOMY/AnatomyManual/back.html

  3. Motions of the Spinal Column • http://www.chiro.org/Vertebral_Subluxation/Anatomy_101.shtml • Flexion approximates the anterior vertebral bodies and separates the spinous processes • Extension approximates the spinous processes and the anterior vertebral bodies separate • Side bending • Rotation • Compression/ Distraction • Anterior/Posterior/Lateral Shear

  4. Disk Disease • A: breakdown of the annulus (Herniation) • B: nucleus pressing against outer annulus (Protrusion) Protrusion= • C: extrusion of nuclear material, but still in contact with the disk (Extrusion) • D: free sequestration of the nuclear material (nuclear material has separated from the disk)

  5. Effects of Posture/Position on Intervertebral Disk Pressure • http://pilatesatthebungalow.com/Pilates/Welcome.html

  6. Passive Lumbar Extension • May have to start with pillows under the abdomen • Allow 5-10 mins. within each position before progressing • Symptoms should decrease and/or centralize, if they increase…STOP!

  7. Lateral Shift Correction

  8. Self Correction of Lateral Shift Standing Back Bend

  9. Self Correction of a Lateral Shift(when there is deviation of the trunk as it flexes) • Patient flexes the lower extremity opposite the side of the shift and places it on a chair with about 90˚of hip flexion • They flex their trunk over the raised thigh and apply pressure by pulling up on the ankle
