Validity of MRI and Ultrasound Volume Measurements of Foot Muscles and Plantar Fascia Cross-Sectional Area Within Older Adults With and Without Chronic Plantar Fasciitis.
Article in Journal of foot and ankle research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionIntrinsic 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.
methodsFoot 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.
resultsHigh 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%.
conclusionsUS 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.
