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.
本研究选取了20名表现出距下关节过度内旋的跑步者，目的是研究外在后足支撑矫形器对额状面后足和胫骨位置的影响。针对三种不同情况测量并比较了许多时间事件：丙烯酸支撑、Birko支撑和无支撑。结果表明，后足支撑在足部矫形治疗中的功能较为有限，支撑材料的选择功能价值有限。
