A conceptual look at rearfoot motion.
A conceptual look at rearfoot motion and the interaction of the axes of the rearfoot is presented. The importance of midtarsal joint stability is discussed, and a question is raised as to what creates stability in the midtarsal joint. Finally, the nature of orthosis function and the effect these devices have on the midtarsal joint for stability and function are discussed.
