The purpose of this study was to establish the effect of simple non moulded flat based insoles on three-dimensional foot motion during normal walking. Excessive foot pronation is considered a major contributing factor to lower limb injuries. Moulded foot orthoses have been shown to decrease maximum foot eversion. Simple insoles are widely used in clinical practice as an alternative to moulded orthoses. However, there has been little research into the kinematic effects of simple insoles.
All subjects had an inverted rearfoot and forefoot position when the subtalar joint was placed in neutral, which was assessed by a weight bearing goniometer. Rotations of the whole foot about three orthogonal axes relative to the shank were estimated using a five camera motion analysis system.
Biplanar insoles significantly (P < 0.05) reduced maximum eversion by an average of 3.1 degrees when compared to the no insole condition. The cobra insole reduced maximum eversion by an average of 2.1 degrees when compared to the no insole condition. This difference approached statistical significance (P = 0.058).
Biplanar and cobra insoles had no significant effect on maximum dorsiflexion, abduction or rate of eversion, when compared to the no insole condition. These results provide some limited support for the use of simple insoles to control for excessive foot pronation during walking.
本研究的目的是确定简单的非模制平底鞋垫对正常行走过程中三维足部运动的影响。足部过度内旋被认为是下肢损伤的主要促成因素。已证明模制足部矫形器可减少最大足外翻。简单鞋垫作为模制矫形器的替代品在临床实践中广泛使用。然而，关于简单鞋垫的运动学影响的研究很少。
当距下关节处于中立位时，所有受试者的后足和前足均处于内翻位置，这通过负重测角计进行评估。使用五相机运动分析系统估计全足相对于小腿围绕三个正交轴的旋转。
与不使用鞋垫的情况相比，双平面鞋垫显著（P < 0.05）降低了最大外翻，平均降低了3.1度。与不使用鞋垫的情况相比，眼镜蛇鞋垫使最大外翻平均降低了2.1度。这种差异接近统计学显著性（P = 0.058）。
与不使用鞋垫的情况相比，双平面鞋垫和眼镜蛇鞋垫对最大背屈、外展或外翻速率没有显著影响。这些结果为使用简单鞋垫控制行走过程中的足部过度内旋提供了一些有限的支持。
