Biomechanical analysis of running with 25 degrees inverted orthotic devices

The purpose of this study was to evaluate the effectiveness of two different rigid foot orthotic devices in controlling subtalar joint subluxation and pronation. A high-speed video analysis system was used to record, store, and analyze data from seven runners: 1) barefoot, 2) shoes only, 3) shoes and vertical orthoses, and 4) shoes with 25 degrees inverted orthotic devices. The results indicate the need for suitable studies, on a larger population group, to evaluate the effect of a variety of orthotic devices on running biomechanics.
