Abstract

Aim

The purpose of this study was to assess and evaluate the effect of a bespoke Modified UCBL Foot Orthosis (MUFO) using both kinetic parameters (Centre of Pressure (CoP) and the Ground Reaction Force (GRF) pattern) and comfort scores in subjects diagnosed with flat foot.

Method

This study included thirty-four young adults with symptomatic flatfeet. Two Kistler force plates (100 Hz) were used to record the CoP sway and GRF pattern during four conditions; 1) an MUFO and standard-fit shoe; 2) the University of California-Berkley Lab (UCBL) insole and standard-fit shoe; 3) barefoot and 4) standard-fit shoe only. The magnitude of subject comfort with UCBL and MUFO also was measured by a 10 cm Visual Analogue Scale (VAS) during walking.

Results

The MUFO decreased mean lateral displacement in the initial phase and midstance of gait compared to barefoot walking. During the propulsion phase use of the new MUFO produced more lateral excursion with a mean difference of 3 mm) P < 0.001(compared to barefoot walking and standard shoe wear. No significant difference in comfort rate was found between the MUFO and UCBL (P = 0.165).

Conclusion

The MUFO produced effective pronation control and decreased the CoP displacement in all of stance phase.

利用动力学测量和用户舒适度评分，评估定制的改良型 UCBL 足部矫形器对扁平足受试者的效果：随机对照试验

本研究的目的是通过动力学参数（压力中心（CoP）和地面反作用力（GRF）模式）和舒适度评分，评估定制的改良型 UCBL 足部矫形器（MUFO）对被诊断为扁平足的受试者的影响。在四种情况下使用两块 Kistler 力板（100 Hz）记录 CoP 摇摆和 GRF 模式：1）MUFO 和标准合脚鞋；2）加州大学伯克利分校实验室（UCBL）鞋垫和标准合脚鞋；3）赤足和 4）仅标准合脚鞋。结果与赤足行走相比，MUFO减少了步态初始阶段和中段的平均侧向位移。在推进阶段，与赤足行走和穿标准鞋相比，使用新型 MUFO 产生了更多的侧向偏移，平均差异为 3 毫米（P < 0.001）。MUFO 和 UCBL 在舒适度方面没有明显差异（P = 0.165）。

期刊介绍： The Foot is an international peer-reviewed journal covering all aspects of scientific approaches and medical and surgical treatment of the foot. The Foot aims to provide a multidisciplinary platform for all specialties involved in treating disorders of the foot. At present it is the only journal which provides this inter-disciplinary opportunity. Primary research papers cover a wide range of disorders of the foot and their treatment, including diabetes, vascular disease, neurological, dermatological and infectious conditions, sports injuries, biomechanics, bioengineering, orthoses and prostheses.
