The research value of the Motion Analysis System, within its scope of limitations, is large and may allow the podiatrist to lend scientific data to support many areas that have been previously held to be of a theoretic or anecdotal basis. The whole concept of rearfoot control with orthoses is perhaps the most important of these. Podiatrists have been aware of the role of orthoses for years, but now there is the means to demonstrate these findings to other medical professions. The ability to compare a number of clinical variables is another truly useful feature. The Motion Analysis System and other similar equipment are not designed to replace or make obsolete the biomechanical examination and "trained human eye;" rather, they act to compliment these skills and to help bring the realm of podiatric biomechanics and orthotic therapy into the scientific arena.
