NonNeutral Motion Mechanics

Type II coupled movement is characterized by sidebending and rotation occurring in the same direction. For example, when the lumbar spine is in flexion (forward-bending) right rotation results in right sidebending and left rotation results in left sidebending. Join Dr. Philip E. Greenman, D.O., F.A.A.O., as he discusses nonneutral (Type II) motion mechanics in the lumbar spine.

Motion of cervical segments C2 through C7 is always characterized by nonneutral motion mechanics. For example, the cervical spine rotates and sidebends to the side regaurdless of whether it is flexed, extended, or in a neutral position. Join Dr. Philip E. Greenman, D.O., F.A.A.O., as he discusses nonneutral (Type II) motion mechanics in the cervical spine.
