Twenty runners displaying abnormal subtalar joint pronation were selected for this study, the purpose of which was to investigate the effects of extrinsic rearfoot posted orthoses on frontal plane rearfoot and tibial position. Numerous temporal events were measured and compared for three different conditions: acrylic post, Birko post, and no post. The results suggested that rearfoot posts have a somewhat limited function in foot orthotic therapy and that the choice of posting material is of limited functional value.
