Abstract

Introduction: Intrinsic foot muscles and the plantar fascia are crucial for foot health, which diminishes with age and conditions such as chronic plantar fasciitis (PF). Ultrasound (US) is an accessible and cost-effective method for evaluating these structures. This study aims to assess the repeatability, reliability, and validity of plantar fascia thickness and flexor digitorum brevis (FDB) muscle measurements using US compared with MRI in individuals with and without PF.

Methods: Foot muscle volume and plantar fascia thickness were measured via US and MRI in 28 participants with and without PF. Subsequently, the plantar fascia thickness and FDB volume were calculated using the OsiriX semiauto volume segmenter software for MRI and the truncated cone formula for both MRI and US. Intraclass correlation coefficients (ICCs), Pearson product correlations (r), minimal detectable differences (MDD), and standard error of measurement (SEm) were calculated.

Results: High ICCs (r = 0.988-0.990) indicated excellent repeatability for all measurement techniques of the plantar fascia and FDB muscle. Reliability for plantar fascia and FDB measurements ranged from 3.98% to 5.50% and 5.06%-9.84%, respectively, across both groups. Validity was high with correlation values between 0.94 and 0.99 and Bland-Altman limits of agreement ranging from 2.6% to 9.2%.

Conclusions: US provides repeatable, reliable, and valid measurements of plantar fascia thickness and FDB muscle volume compared with MRI. It offers a cost-effective and accessible alternative for assessing foot health in clinical and research settings.

有或无慢性足底筋膜炎的老年人足部肌肉和足底筋膜横截面积的MRI和超声体积测量的有效性。
内在足部肌肉和足底筋膜对足部健康至关重要,随着年龄的增长和慢性足底筋膜炎(PF)等疾病的发生而减少。超声(US)是评估这些结构的一种方便且经济有效的方法。本研究旨在评估在患有和不患有前列腺炎的个体中,使用US与MRI比较足底筋膜厚度和指短屈肌(FDB)测量的可重复性、可靠性和有效性。通过US和MRI测量了28名患有和不患有PF的参与者的足部肌肉体积和足底筋膜厚度。随后,使用MRI的OsiriX半自动体积分割软件和MRI和US的截锥公式计算足底筋膜厚度和FDB体积。计算了类内相关系数(ICCs)、Pearson积相关性(r)、最小可检测差异(MDD)和测量标准误差(SEm)。结果:高ICCs (r = 0.988 ~ 0.990)表明足底筋膜和FDB肌的所有测量技术具有良好的重复性。两组足底筋膜和FDB测量的可靠性分别为3.98% ~ 5.50%和5.06% ~ 9.84%。效度高,相关值在0.94 ~ 0.99之间,Bland-Altman一致性限在2.6% ~ 9.2%之间。结论:与MRI相比,US提供了可重复、可靠和有效的足底筋膜厚度和FDB肌肉体积测量。它为临床和研究环境中评估足部健康提供了一种具有成本效益和可获得的替代方案。

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.
