Ascending Foot Cranial Model  - links abnormal foot motion to facial and/or cranial imbalances as follows:

  • (1) If the foot has a structurally elevated first metatarsal (e.g., Rothbarts Foot), gravity in combination with the body's weight forces the foot to move forward, inward and downward (e.g., gravity driven pronation) until the first metatarsal rests on the ground (Rothbart and Esterbrook, 1988).
  • (2) This gravity driven pronation can unlevel the innominates (e.g.,tilt or drive the innominates into anterior rotation) (Rothbart and Esterbrook, 1988; Rothbart, 2006; Khamis and Yizhar, 2007; Pinto, Souza et al, 2008))
  • (3) Anterior rotation of the innominates can drive the temporal bones into posterior (external) rotation.** This rotation changes the Vhf *(Rothbart, 2008)


Vhf - distance between the outer orbit of the eye and the ipsilateral outer margin of the lip.  An asymmetry >3mm is clinically significant.

Standing “neutral” position of the pelvis is that position where both the posterior superior and anterior superior iliac spines sit on the horizontal plane (Kendall, 1983).
