Based on embryological studies, I propose that hyperpronation in the adult
[gaiting] foot is the result of an ontogenetic retention of talar torsion
[termed talar supinatus] seen during weeks 6pf-8pf in the developing embryo.
Clinically, talar supinatus is visualized as an elevation of the medial
column of the foot [termed Primus Metatarsus Elevatus], in the
standing/neutral positioned foot. I have devised a way to measure PME using
microwedges with confirmed high interrator reliability. I have introduced a
way to reduce hyperpronation resulting from PME using postural insoles [not
orthotics which weaken the feet]. Postural are based on Proprioceptive
Feedback Stimulation, and are not used as supportive devices [e.g., arch
supports/metatarsal bars or pads, etc].
My work has been accepted for publication [January 2002] in the Journal
of Bodywork and Movement Therapy [Harcourt Publishers, Leon Chaitow Editor].
