Uncovering the alterations in extrinsic foot muscle mechanical properties and foot posture in fibromyalgia: a case-control study.
Article in Rheumatology international, 2024. 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
objectivesThe aim of the study was to evaluate foot posture and the mechanical properties of extrinsic foot muscles in fibromyalgia.
methodsPatients with fibromyalgia (n = 86) and age- and gender-matched controls (n = 41) were included in the study. Foot Posture Index (FPI), Beighton and Brighton criteria were used to evaluate static foot posture, joint hypermobility, and benign joint hypermobility syndrome (BJHS), respectively. Tonus, elasticity, and stiffness of the extrinsic foot muscles including gastrocnemius medialis, tibialis anterior, and peroneus longus were measured by the MyotonPRO
resultsThe frequency of abnormal foot posture in the fibromyalgia and control groups was 68.6% versus 39%, respectively; and neutral foot posture was approximately twice as prevalent in the control group compared to the fibromyalgia group (p = 0.006). Pronated foot posture was the most common abnormality in fibromyalgia (61.6%) and observed in 85.5% of the patients with joint hypermobility and in 87.1% of those meeting BJHS criteria. The elasticity of peroneus longus at rest and the elasticity of tibialis anterior in the standing position were significantly different between the fibromyalgia group and the control group [1.08 (0.22) vs. 1.02 (0.25), p = 0.037 and 0.92 (0.29) vs. 0.87 (0.24), p = 0.011, respectively]. Regarding the fibromyalgia group, no difference was detected among foot posture groups in terms of myotonometric data.
conclusionsPronation foot posture is common in fibromyalgia with a much higher frequency in fibromyalgia patients with hypermobility. In daily clinical practice for fibromyalgia, particular attention should be given to foot alignment.
