I. When the thoracic and lumbar spine are in a
neutral position, the coupled motions of
sidebending and rotation for a group of
vertebrae are such that sidebending and
rotation occur in opposite directions
Type I Somatic Dysfunction
• Group Mechanics of Three or More Vertebral Segments, When Neutral Sidebending is Introduced, Rotation Occurs To The Opposite Side
• Maintained By Long Postural Muscles
• Treat in Neutral
II. When the thoracic and lumbar spine are
sufficiently flexed or extended (non-neutral), the
coupled motions of sidebending and rotation in a
single vertebral unit are such that sidebending and
rotation occur in the same direction.
Type II Somatic Dysfunction
• Maintained By Short Muscles
• With Hyper Flexion or Extension, Rotation and Sidebending Occur To The Same Side
• Rotation Occurs Around The “Locked” Facet
• The Facet, “Opened or Closed”, Describes the Motion and Is Not The Lesion
• FRS/ERS
III. 1. Initiating motion of a vertebral segment in
any plane of motion will modify the movement
of that segment in other planes of motion.
