Abstract

Background: Traditionally, gait analysis studies record the foot as a single rigid segment, leaving movements and loads within the foot undetected. In addition, very few data of multi-segment foot kinetics have been represented in the literature due to measurement and equipment limitations. As a result, this study aims to develop a novel multi-segment kinetic foot model that is clinically feasible and enables both kinematic and kinetic analysis of large patient groups.

Results: Outcome measurements include rotation angles of intersegmental dorsi/plantar flexion, inversion/eversion, and internal/external rotation, joint moments, joint powers and the medial longitudinal arch (MLA) height/length ratio. Repeatability of joint motions was calculated using coefficients of multiple correlation. Most joint motions measured by this foot model showed strong within-subject reliability (R > 0.7) in healthy adults. Outcome measures were in agreement with other multi-segment foot models found in the biomechanics literature.

Conclusions: This novel multi-segment foot model is able to quantify intersegmental foot kinematics and kinetics and can be a useful tool for research and assessments on clinical populations.

一种临床上有用的多节段足部动力学模型的建立。

传统上，步态分析研究将足部记录为单个刚性部分，使足部的运动和负荷未被检测到。此外，由于测量和设备的限制，文献中很少有多段足部动力学的数据。因此，本研究旨在开发一种新的多节段足部动力学模型，该模型在临床上是可行的，并且能够对大型患者群体进行运动学和动力学分析。结果:结果测量包括节段间背/足底屈曲、内翻/外翻、内旋/外旋旋转角度、关节力矩、关节力量和内侧纵弓(MLA)高度/长度比。采用多重相关系数计算关节运动的重复性。该足部模型测量的大多数关节运动在健康成人中显示出很强的受试者内可靠性(R > 0.7)。结果测量与生物力学文献中发现的其他多节段足部模型一致。结论:这种新颖的多节段足部模型能够量化节段间足部运动学和动力学，可以成为临床人群研究和评估的有用工具。

期刊介绍： Journal of Foot and Ankle Research, the official journal of the Australian Podiatry Association and The College of Podiatry (UK), is an open access journal that encompasses all aspects of policy, organisation, delivery and clinical practice related to the assessment, diagnosis, prevention and management of foot and ankle disorders. Journal of Foot and Ankle Research covers a wide range of clinical subject areas, including diabetology, paediatrics, sports medicine, gerontology and geriatrics, foot surgery, physical therapy, dermatology, wound management, radiology, biomechanics and bioengineering, orthotics and prosthetics, as well the broad areas of epidemiology, policy, organisation and delivery of services related to foot and ankle care. The journal encourages submissions from all health professionals who manage lower limb conditions, including podiatrists, nurses, physical therapists and physiotherapists, orthopaedists, manual therapists, medical specialists and general medical practitioners, as well as health service researchers concerned with foot and ankle care. The Australian Podiatry Association and the College of Podiatry (UK) have reserve funds to cover the article-processing charge for manuscripts submitted by its members. Society members can email the appropriate contact at Australian Podiatry Association or The College of Podiatry to obtain the corresponding code to enter on submission.
