Lesson Plan

Part 1

Some Chiropractic researchers have hypothesized that facet and odontoid architecture variations can cause a reduction in cervical lordosis. To evaluate this hypothesis, Dr. Deed Harrison discusses how the Sagittal plane anatomical variations (angulation) of the Cervical Facets and C2 Odontoid affect the geometrical configuration of the Cervical Lordosis.

Learn easy practical solutions for patients and clients

  • Identify the correlation, if any, between the facet angle, articular pillar height, and cervical curve.
  • Identify the correlation, if any, between the sagittal angle of the dens and any angle of cervical curvature.
  • Conclude whether the conservative and surgical rehabilitative techniques aimed at the reduction of sagittal cervical deformities need to account for a patient’s architecture of the cervical facets or odontoid.

Duration: 25 minutes

Part 2

Dr. Deed Harrison discusses one of the important components of altered posture on the thoracic spine and its influence on disk loads. Early disk degeneration can turn into disk disease and/or a cascade of back and overall health problems. The objective of this video is to characterize changes in thoracolumbar disc loads and extensor muscle forces following anterior translation of the thoracic spine in the upright posture.

Learn easy practical solutions for patients and clients

  • Understand the relationship between trunk posture, spine geometry, extensor muscle activity, and the loads and stresses acting on the IVD.
  • Learn how positions through posture of the thoracolumbar spine influence and contribute to disk mechanical loading.
  • Recognize how trunk muscular activity is strongly influenced by upright posture alignment

Duration: 28 minutes
