Sagittal Plane Postural Analysis

Ascending Postural Distortion Pattern (Rothbart 2002)

  • Gravity drive (abnormal) right foot pronation
  • Drives the right innominate into the anterior rotation, which
  • Drives the right temporal bone into posterior (external) rotation (clinically observed as a decrease in the Facial Vertical height

Postural Analysis (See Animation above)

  • Abnormal pronation - Right > Left
  • Anterior rotation of Innominates - Right > Left
  • Supine, right leg appears longer 

Functional Leg Length Discrepancy occurs with asymmetrical abnormal foot pronation (Rothbart 2006)  

Two of the most common foot structures that result in abnormal foot pronation are

  • Rothbarts Foot and
  • PreClinical Clubfoot Deformity

Coupling of Temporal to Sphenoid -  

  • Posterior (external) Temporal  Rotation 
  • Sphenoid Flexion
  • Long and Narrow cranium (see Photo above)

Reciprocity between the innominate bones and the temporal bones (Abnormal Pronation vs Malocclusion)

Abnormal Pronation ​(Ascending Pattern)

  • Abnormal Pronation drives the innominate bones into an anterior (external) rotation
  • Anterior rotation of the innominate bone drives the temporal bones into a posterior (external) rotation. 

Ascending Pure Postural Distortion Pattern-Update July 2019

Malocclusion (Descending Pattern)

  • Malocclusion drives the temporal bones into an anterior (internal) rotation.  
  • Anterior (internal) rotation of the temporal bones drives the innominate bones into a posterior rotation (Lovett, 1905).
