Two Distinct Tonus Patterns Seen in Abnormal Pronators - Research Study

Current Research - Releasers vs Bracers

Shoe Wear Patterns - Bracers vs Releasers

Shoe wear patterns seen with different tonicity patterns

Preliminary Data

Cuernavaca Study

Cartesian Graph

Significance of Cartesian Graph

• The most common bracer (hypertonus patient) seen clinically is a patient having the Primus Metatarsus Supinatus Foot Structure (aka Rothbarts Foot)
• The most common releaser (hypotonus patient) seen clinically is a patient having the PreClinical Clubfoot Deformity

Progression of Weight Bearing Forces

• Figure Right - progression of weight bearing forces across the foot in a bracer (outside heel to inside forefoot)
• Figure Left -   progression of weight bearing forces corrected using Proprioceptive Insoles

• Figure Left -   progression of weight bearing forces across the foot in a releaser (inside heel to inside forefoot)
• Figure Right - progression of weight bearing forces corrected using Proprioceptive Insoles
