All 17 patients are fitted with medial column foot insoles. Two sets of surface area (X) and media pressure (Y) readings are recorded on each patient: a baseline set before treatment and a second set after treatment. The observed changes in surface area (∆X) and media pressure (∆Y) are statistically correlated: (1) are ∆X∆Y patterns randomized events or are they the result of medial column insole therapy, and (2) if the ∆X∆Y patterns are the result of insole therapy, do they have any correlation to postural tonicity? The results are compelling: (1) the probability that these patterns are randomized events (based on chance alone) is exceeding small (p <.01) and, (2) there is a high level of confidence that postural tonicity shifts towards homeostasis when insole therapy is effective. From a clinical point of view, ∆X∆Y patterns may prove useful ...

He terms this foot structure Primus Metatarsus supinatus (PMs). Rothbart suggests that PMs is the end result of a failed or incomplete unwinding of the talar head. Clinically, the 1st metatarsal and hallux are off the ground when the standing foot is placed in its anatomical neutral position. This distance between the 1st metatarsal and ground, referred to as the PMs value, is quantified using microwedges. PMs values between 10 mm and 30 mm define the Rothbart Foot structure (RFs). RFs is biomechanically dysfunctional, demarcated by its prolonged mid-stance hyperpronation. Dynamic hyperpronation shifts the posture forward: (1) the innominates rotate anteriorly, (2) the pelvis unlevels, augmenting the scoliotic and kyphotic curves, (2) the shoulders protract, and (3) the head moves forward relative to the cervical spine. Rothbart terms this shift in posture BioI...

Le systeme (60) de support pour pied est forme d'un lit sur lequel le pied (20) repose et qui comprend un bord interieur (62) et un bord exterieur (64). Le systeme (60) de support pour pied est place sous la colonne mediale de l'avant-pied. Le systeme (60) diminue lateralement en epaisseur a partir du bord interieur (62) vers le bord exterieur (64). Le bord interieur (62) est place le long du cote medial du pied (20) et le bord exterieur (64) est place longitudinalement dans une zone adjacente au bord lateral du gros orteil (48), de la phalange proximale (46) et du premier metatarsien (36), et au bord medial des phalanges (47), du second orteil et du second metatarsien (38).

T... more Clinical data suggests cranial imbalances and malocclusions are linked to abnormal foot motion. This paper discusses the impact abnormal foot motion can have on the cranial bones and occlusion. This coupling between the foot - cranium - occlusion is presented and linked (initiated) by two abnormal inherited foot structures (PreClinical Clubfoot Deformity and Primus Metatarsus Supinatus/aka Rothbarts Foot). A novel proprioceptive therapy is discussed that stabilizes these two abnormal foot structures and reverses (in children) or stabilizes (in adults) cranial imbalances and malocclusions.

Section I describes this foot-cranial linkage in laymen's terminology. Section II describes this foot-cranial coupling in medical terminology. Section III describes an embryonic foot type that frequently is responsible for distortions in the cranial bones (hereafter referred to as cranial lesions). Section IV describes a novel foot insole (referred to as a proprioceptive activator) which effectively reverses (in children) or stabilizes (in adults) cranial lesions. The foot-cranial correlations presented in this paper are based on a recently concluded clinical study in Juetepec Mexico. (Statistical Study currently in peer review for publication.)

The most common type of scoliosis in this age group is one in which the cause is unknown, and still referred to as Adolescent Idiopthic Scoliosis. I have long suspected a link between abnormal foot motion (gravity drive pronation) and the development of abnormal curves in the spinal cord. A study I published in 2006 (JAPMA) statistically linked the unleveling of the pelvis, which forms the base of the spine, to abnormal foot pronation. It is only logical to suspect that if the base of the spine is unlevelled, it could also unlevel the entire spine. This was my motivation that led to this study. It is to be noted that this is a preliminary study and certainly needs to be repeated using a larger sample size. However, the outcome of this study does suggest that the development of scoliosis may indeed be linked to abnormal foot motion.

This paper discusses: (1) The Ontogenesis of each of these two foot structures (2) The Knee Bend Test used in the differential diagnosis (3) The link between chronic pain and these foot structures

If these torsional growth patterns ends prematurely, it can result in the elevation and inversion (supinatus) of the medial column of the foot (aka Rothbarts Foot). This structural foot deformation forces the foot to collapse during gait: weight bearing joints become mal-aligned and postural muscles compensate by tightening. In time, these joint and muscle changes lead the patient into chronic musculoskeletal pain, foot to jaw.

(2) If this torsional growth in the talar head ends prematurely, the 1st metatarsal, proximal phalanx and hallux remain in supinatus (structurally elevated and inverted). Postnatally, when standing, gravity pulls the elevated 1st metatarsal and adjoining phalanx and hallux downward to the ground. As the 1st metatarsal, phalanx and hallux collapse to the ground, the body shifts into a kyphotic posture. As a result, weight bearing joints become mal-aligned and postural muscles compensate by tightening. In time, these joint and muscle changes lead the patient into chronic musculoskeletal pain.

Normal (Hip Driven) pronation sends non distorted signals to the Cerebellum resulting in non distorted posture.
Abnormal (Gravity Driven) pronation sends distorted signals to the Cerebellum resulting in distorted posture.

Both of these inherited foot structures results in global postural distorsional patterns (joint malaligments and muscle hypertonicity). Eventually these distorted postural patterns result in chronic musculoskeletal pain.
A Proprioceptive Model is presented which describes the link between foot motion and cerebellar function:
(1) Abnormal foot motion send distorted signals to the cerebellum.
(2) The cerebellum acts on these distorted signals which results in distorted posture.

A type of Proprioceptive Therapy is described which normalizes the signals being sent to the cerebellum. This results in an automatic correction in posture and an attenuation in the resulting symptomatology.

That has changed!

Professor/Dr. Brian A. Rothbart has spent over 40 years in research and clinical practice and has discovered two inherited, abnormal foot structures – the Rothbarts Foot and the Preclinical Clubfoot Deformity - that predispose over 80% of the world population to chronic muscle and joint pain. If you live with debilitating or disabling chronic pain, one of these common foot structures could be the source of your problem.

In this book one will learn:

Exactly how the feet may have created chronic pain throughout one's entire body

How to tell if one may have a Rothbarts Foot or PreClinical Clubfoot Deformity

A new therapy that can effectively treat one's foot structure and PERMANENTLY greatly reduce or completely eliminate one's chronic muscle and joint pain.

When the foot is structurally unstable (e.g., PreClinical Clubfoot Deformity, Rothbarts Foot), the signals to the cerebellum are distorted which results in a distorted posture globally. When the alignment of the body is distorted, it frequently results in chronic muscle and joint pain.

A second set of surface area and media pressure readings were then recorded after each subject used their proprioceptive insoles for 60 seconds. The collected data was statistically analyzed using 'Best Fit' Hypothesis. The results of the 'Best Fit' Hypothesis suggest that prescriptive proprioceptive insoles shift postural tonicity patterns towards homeostasis. From a clinical point of view, pressure plate readings may prove useful in prognosticating the appropriateness of specific prescriptive proprioceptive insoles when treating either PreClinical Clubfoot Deformity or Rothbarts Foot patients.
