Before you learn about our posture correcting, pain-controlling Theta-Orthotics, you should understand a little about orthotics because Theta design came from research with traditional medically prescribed orthotics.
Arch support is a concept that has been understood and applied for hundreds of years. Early researchers in foot function identified three arches in the human foot. These arches were known as the medial longitudinal, lateral longitudinal, and the transverse metatarsal arches.
All researchers recognized the significance in maintaining these arches as a requirement for proper foot function. All recorded destructive changes in the arches when foot deformity and pain is present.
Not long after these arch supports, came a series of patents using materials contoured to a mold of the bottom of the human foot. Over the years, these hard-contoured plates were changed with increased angles and posts to maintain that changed angular position during walking. These devices were called orthotics.
The purpose of an orthotic is to improve foot and leg function with intent to heal the problems generated in the structures they affect. The benefit of an orthotic is directly related to how well it can improve foot and leg function.
Qualitatively, both arch supports and orthotics contour the plantar foot, apply support to the arches, and reduce foot pronation.
Quantitatively, the part of orthotic design related to foot function has never been defined and measured. Even though many researchers in the field of human biomechanics have understood the importance of the wedge in orthotics design none have quantified the wedged portion of their device, and orthotic treatment has remained more of an art than a science. Without quantification no one could define or measure the difference between the many different devices on the market.
