The aim of this study was to quantify the effect of anti-pronatory and anti-supinatory foot orthoses on the angular displacement, velocity and accelerations of the rearfoot complex during gait. The transverse plane motion of the leg relative to the foot was used to indicate rearfoot complex pronation and supination. Three dimensional gait analysis on 12 subjects was used to derive the changes in the rearfoot kinematics due to the orthoses. The anti-pronatory orthoses decreased the range of pronation during the contact phase (p=0.0002) and the total range of rearfoot complex motion (p=0.000002), whereas anti-supinatory orthoses increased the range of pronation during the contact phase (p=0.00006) and the total range of rearfoot motion (p=0.049). Anti-pronatory orthoses also decreased the initial peak in pronation velocity during the contact phase of gait (p=0.006). Neither orthosis had a statistically significant effect on rearfoot complex acceleration.
本研究的目的是量化抗旋前和抗旋后足部矫形器对步态期间后足复合体角位移、速度和加速度的影响。腿部相对于足部的横断面运动用于指示后足复合体的旋前和旋后。对12名受试者进行三维步态分析，以得出由于矫形器导致的后足运动学变化。抗旋前矫形器减少了着地阶段的旋前范围（p = 0.0002）以及后足复合体运动的总范围（p = 0.000002），而抗旋后矫形器增加了着地阶段的旋前范围（p = 0.00006）以及后足运动的总范围（p = 0.049）。抗旋前矫形器还降低了步态着地阶段旋前速度的初始峰值（p = 0.006）。两种矫形器对后足复合体加速度均无统计学上的显著影响。
