Gravity Drive Pronation Linked to Cranial Frontal Plane Distortions

    A research study completed in 2012 and published in 2013 (JCMSP)) radiographically demonstrated the link between Gravity Drive Pronation and distortions in the frontal plane position of the cranial bones.

    Attached is an animation that pictorially demonstrates this foot to cranial link:

    1. Gravity Drive (abnormal) Pronation of the left foot drives the left innominate bone anteriorly.
    2. Anterior rotation of the left innominate bone drives the left temporal bone posteriorly.
    3. The posterior rotation of the temporal bones (left > right)
    Flexes the sphenoid
    Rotates the sphenoid downward (left sphenoid torsion)​

    This frontal plane distortion in the sphenoid bone was radiographically demonstrated and linked to asymmetrical gravity drive pronation patterns.

    Headaches, insomnia, personality and visual aberrations - these are some of the symptoms that could result from frontal plane cranial distortions.
    • I suggest this structural alteration can increase the intercranial pressure gradients and result in CNS symptoms.
    In my practice I have seen seemingly unrelated cranial symptoms abate with the use of the appropriate insole. Conversely, inappropriate use of insoles may initiate or exacerbate CNS symptoms.

    Just another reason that due diligence must be exercised when any type of insole or orthotic is placed underneath the feet.
