Objective.目的：量化内侧足矫形器在跑步站立阶段对跟骨和胫骨骨骼运动的影响。使用跟骨和胫骨处的骨骼（和鞋）标记测试内侧足矫形器（前部、后部、无支撑）的运动学效应。先前使用鞋和皮肤标记的研究得出结论，内侧放置的矫形器控制/减少足外翻和胫骨旋转，但是，目前尚不清楚此类矫形器是否也影响下肢的骨骼运动。方法.在标准局部麻醉下，将具有反射标记三联体的皮质内霍夫曼针插入5名健康男性受试者的跟骨和胫骨中。使用关节坐标系方法确定三维胫跟旋转。通过计算足外翻（胫骨外翻和足外翻）和胫骨旋转来研究足矫形器的效果。在所有受试者中，发现矫形器对外翻和胫骨旋转的影响很小且不系统。受试者之间的差异（p < 0.01;高达10度）显著大于矫形器条件之间的差异（1-4度）。仅在胫骨内旋方面发现了显著的矫正效果，p < 0.05）。这项体内研究表明，在跑步的站立阶段，内侧放置的足部矫形器并没有显著改变胫跟骨的运动模式。
Objective. To quantify the effects of medial foot orthoses on skeletal movements of the calcaneus and tibia during the stance phase in running.Design. Kinematic effects of medial foot orthoses (anterior, posterior, no support) were tested using skeletal (and shoe) markers at the calcaneus and tibia.Background. Previous studies using shoe and skin markers concluded that medially placed orthoses control/reduce foot eversion and tibial rotation, However, it is currently unknown if such orthoses also affect skeletal motion at the lower extremities. Methods. Intracortical Hofman pins with reflective marker triads were inserted under standard local anesthetic into the calcaneus and tibia of five healthy male subjects. The three-dimensional tibiocalcaneal rotations were determined using a joint coordinate system approach. Eversion (sketetal and shoe) and tibial rotation were calculated to study the foot orthoses effects.Results. Orthotic effects on eversion and tibial rotations were found to be small and unsystematic over all subjects, Differences between the subjects were significantly larger (p < 0.01; up to 10 degrees) than between the orthotic conditions (1-4 degrees). Significant orthotic effects across subjects were found only for total internal tibial rotation, p < 0.05).Conclusions. This in vivo study showed that medially placed foot orthoses did not change tibiocalcaneal movement patterns substantially during the stance phase of running.
