The purpose of this study was to quantify effects of shoe sole modification on skeletal kinematics of the calcaneus and tibia during the stance phase of running.
Intracortical bone 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. Three shoe sole modifications were tested with different sole geometry: a lateral heel flare of 25 degrees (flared), no flare 0 degrees (straight), and a rounded sole.
The results showed that these shoe sole modifications did not change tibiocalcaneal rotations substantially. The shoe sole effects at the bone level were small and unsystematic (mean effects being less than 1 degrees ) compared with the differences between the subjects (up to 7 degrees ). Shoe eversion measured simultaneously with shoe markers showed no systematic shoe sole effects. A comparison of shoe and bone results showed the total shoe eversion and maximum shoe eversion velocity to be approximately twice as large as the respective measurements based on bone markers (correlations being r = 0.79 for maximum eversion velocity; r = 0.88 for total eversion), indicating that there may be a relationship or coupling effect between the shoes and the bone.
It is concluded that the tibiocalcaneal kinematics of running may be individually unique and that shoe sole modifications may not be able to change them substantially.
本研究的目的是量化鞋底改良对跑步站立阶段跟骨和胫骨骨骼运动学的影响。
在标准局部麻醉下，将带有反光标记三联体的皮质内骨针插入五名健康男性受试者的跟骨和胫骨。使用关节坐标系方法确定三维胫跟旋转。测试了三种具有不同鞋底几何形状的鞋底改良：外侧足跟扩角25度（扩角）、无扩角0度（直底）和圆底。
结果表明，这些鞋底改良并未显著改变胫跟旋转。与受试者之间的差异（高达7度）相比，鞋底在骨骼水平上的影响较小且无系统性（平均影响小于1度）。与鞋底标记同时测量的鞋外翻未显示出系统性的鞋底影响。鞋与骨骼结果的比较表明，总鞋外翻和最大鞋外翻速度约为基于骨骼标记的相应测量值的两倍（最大外翻速度的相关性为r = 0.79；总外翻的相关性为r = 0.88），表明鞋与骨骼之间可能存在关系或耦合效应。
得出的结论是，跑步时的胫跟运动学可能具有个体独特性，并且鞋底改良可能无法显著改变它们。
