Pure Descending Postural Distortion Pattern Resulting from a Forward Head Position
1. Position of the head relative to the cervical spine linked to the central coordination of posture
Cooper BC, Cooper DL, Electromyography of Craniomandibular Disorders, in: Laryngoscope 101: February 1991
2. Forward Head Position results in stretching (hyperIrritability) of the Short Cervical Muscles (Suboccipital Muscles)
3. HyperIrritability of the Short Cervical Muscles (SCM) change eye position and gaze direction. Changing gaze direction, changes posture.
Han Y, Lennerstrand G, Eye position changes induced by neck muscle vibration in strabismic subjects, in: Graefes Arch Clin Exp Ophthalmol 1999 Jan; 237 (1): 21-8
4. HyperIrritability of the SCM linked to postural distortions in the hip.

5. CNS Symptoms of SCM HyperIrritability:
