Abstract
Introduction: The lateral longitudinal arch (LLA) is an essential structure of the foot. However, LLA evaluation methods remain underexplored compared to those of the medial longitudinal arch (MLA). This study sought to develop a method for measuring the cuboid height, the keystone of the LLA, using ultrasonography and to verify its correlation with radiography, as well as intrarater and interrater reliability.
Methods: This cross-sectional study included 21 university students (14 males and seven females). The cuboid height was measured using radiography and ultrasonography. The validity of ultrasonographic measurements was assessed through correlation with radiographic measurements and Bland-Altman analysis. Intrarater and interrater reliabilities were evaluated using intraclass correlation coefficients (ICCs).
Results: A strong correlation was observed between cuboid heights measured using radiography and ultrasonography (r = 0.98, p < 0.01). The Bland-Altman analysis revealed a fixed bias of -0.71 mm (95% confidence interval [95% CI]: -0.96 to -0.46 mm). Intrarater and interrater reliability for ultrasonographic measurements were almost perfect, with ICCs of 0.98 and 0.99, respectively.
Conclusions: Cuboid height measurements using ultrasonography demonstrated high validity and reliability. This method offers a noninvasive and cost-effective alternative to radiography, with potential clinical applications in the evaluation of LLA and related conditions such as cuboid syndrome and lateral foot injuries.
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.
