The Subtalar Joint Axis Palpation Technique: Part 2 - Results on reliability and validity using cadaver feet.

Abstract Background Clinically locating the point of no rotation to determine the subtalar joint axis (STJA) location by applying pressure on the plantar surface of the foot, was described by Kirby in 1987, but never validated. The purpose of this study is to extend a previously validated mechanical model to cadaver feet and to examine the intra-intertester reliability. Methods Four testers, with different levels of experience, determined the STJA location and moved the STJ through its range of motion capturing the movement using kinematic analysis.
