Camptocormia as a Phenotypic Variant of FSHD in the Elderly: Clinical, Genetic, and Imaging Features.
Article in European journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
BACKGROUND AND
objectivesCamptocormia, a pathological forward flexion of the spine, is a relatively common but often unexplained postural abnormality. Facioscapulohumeral muscular dystrophy (FSHD), one of the most prevalent adult myopathies, is caused by a contraction of D4Z4 repeats on chromosome 4 and typically presents with facial, scapular, and lower limb weakness. However, atypical phenotypes are increasingly recognized. We investigated camptocormia as a presenting feature of FSHD in a large neuromuscular cohort.
methodsThis cross-sectional study assessed clinical, genetic, and muscle imaging features in patients with FSHD presenting with camptocormia and compared them to patients with typical FSHD.
resultsAmong 87 patients with genetically confirmed FSHD, 8 (9.1%) had camptocormia as the predominant and initial manifestation. FSHD also accounted for 47% (8/17) of all cases of camptocormia due to axial myopathy. Compared to classical FSHD, camptocormic patients exhibited later disease onset, moderately contracted D4Z4 repeats, and marked axial involvement, with predominant spinal extensor weakness and relatively preserved abdominal strength. Muscle MRI revealed more severe paravertebral involvement and milder serratus anterior involvement than typically observed in FSHD.
conclusionsCamptocormia represents a relatively frequent and distinct phenotypic variant of FSHD, particularly in older adults. Conversely, FSHD is a common cause of camptocormia due to axial myopathy. These findings expand the clinical spectrum of FSHD and underscore the importance of considering FSHD in the differential diagnosis of camptocormia, even in the absence of typical clinical signs of FSHD. Muscle imaging may assist in identifying FSHD-associated camptocormia.
