跑步是一种流行的娱乐形式，但损伤是常见的，可能与关节运动异常有关。本研究的目的是确定三种鞋类条件-赤脚（BF），超柔性训练鞋（FREE）和运动控制鞋(MC) -对3D足部和脚踝运动的影响。从12名跑步者在地上跑步时获得动态的双翼x线摄影图像。根据跖屈/背屈（PF/DF）、内翻/外翻（in /EV）和内/外旋（IR/ER）对胫距和距下关节的三维旋转进行量化。在站立的早期阶段（定义为脚着地到脚跟着地），BF跑比穿鞋跑（自由跑：PF/DF=15.1 +/- 5.9度，IR/ER=4.8 +/- 2.1度；MC跑：PF/DF=15.0 +/- 6.2度，IR/ER=4.3 +/- 0.7度）表现出更大的胫骨关节运动范围（PF/DF= 28.2 +/- 8.3度）和IR/ER（7.0 +/- 1.4度）。同样，在胫距关节处，与两种鞋相比，BF跑步导致的位置明显更跖屈（BF: 2.0 +/- 12.5度，FREE: 15.7 +/- 12.2度，MC: 16.5 +/- 9.3度）和内部旋转（BF: 12.9 +/- 4.5度，FREE: 10.7 +/- 4.3度，MC: 10.6 +/- 3.9度）。在站立早期阶段的任何点，在胫距关节处的鞋面状况之间没有发现差异。与FREE相比，MC在距下关节早期站立阶段的几个点上表现出显著差异，其中PF/DF （MC -1.4 +/- 8.8度：FREE: -0.5 +/- 9.0度）、in /EV （MC -8.1 +/- 5.7度：FREE -6.3 +/- 5.5度）和IR/ER （MC -9.5 +/- 5.3度：FREE: -8.7 +/- 5.2度）的差异最大，为30%。这些结果表明，鞋类对关节运动有微妙的影响，主要是胫骨关节的BF和鞋条件之间以及距下关节的鞋条件之间。(C) 2014 Elsevier Ltd.版权所有。
Running is a popular form of recreation, but injuries are common and may be associated with abnormal joint motion. The objective of this study was to determine the effect of three footwear conditions - barefoot (BF), an ultraflexible training shoe (FREE), and a motion control shoe (MC) - on 3D foot and ankle motion. Dynamic, biplane radiographic images were acquired from 12 runners during overground running. 3D rotations of the tibiotalar and subtalar joints were quantified in terms of plantarflexion/dorsiflexion (PF/DF), inversion/eversion (IN/EV) and internal/external rotation (IR/ER). Across the early stance phase (defined as footstrike to heel-off), BF running demonstrated greater tibiotalar joint range of motion for PF/DF (28.2 +/- 8.3 degrees) and IR/ER (7.0 +/- 1.4 degrees) than the shod conditions (FREE: PF/DF=15.1 +/- 5.9 degrees, IR/ER=4.8 +/- 2.1 degrees; MC: PF/DF=15.0 +/- 6.2 degrees, IR/ER=4.3 +/- 0.7 degrees). Also at the tibiotalar joint, BF running resulted in a position significantly more plantarflexed (BF: 2.0 +/- 12.5 degrees, FREE: 15.7 +/- 12.2 degrees, MC: 16.5 +/- 9.3 degrees) and internally rotated (BF: 12.9 +/- 4.5 degrees, FREE: 10.7 +/- 4.3 degrees, MC: 10.6 +/- 3.9 degrees) at footstrike compared to both shod conditions. No differences were detected between the shod conditions at any point in the early stance phase at the tibiotalar joint. The MC condition demonstrated significant differences compared to FREE at several points throughout the early stance phase at the subtalar joint, with the greatest differences seen at 30% in PF/DF (MC -1.4 +/- 8.8 degrees: FREE: -0.5 +/- 9.0 degrees), IN/EV (MC -8.1 +/- 5.7 degrees: FREE -6.3 +/- 5.5 degrees) and IR/ER (MC -9.5 +/- 5.3 degrees: FREE: -8.7 +/- 5.2 degrees). These findings indicate that footwear has subtle effects on joint motion mainly between BF and shod conditions at the tibiotalar joint and between shod conditions at the subtalar joint.
