Spinal somatic dysfunctions are classified as type I or type II dysfunctions. Type I dysfunctions follow Fryette s first principle of physiologic motion, which states that when the vertebrae are side-bent from a neutral position, rotation will occur in the opposite direction from the side-bending. These are group curves in the thoracic or lumbar regions involving more than... 

Type I and type II dysfunctions refer only to somatic dysfunctions in the thoracic and lumbar vertebrae because Fryette s principles only apply to these areas. However, in common usage, somatic dysfunctions in the typical cervical spine are often referred to as type II, Motion characteristics of the cervical region dictate that the typical cervical vertebrae side-bend and rotate toward the same side regardless of dysfunction or normal functioning. The distinction is the involvement of a flexion or extension component in the dysfunctional unit.
