Acute vertigo and dizziness: the diagnostic potential of static posturography in the neurological emergency department.
Article in Journal of neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundVertigo and dizziness are common in the emergency room, caused by a broad spectrum of conditions ranging from life-threatening to non-organic causes such as functional dizziness. The latter is often underdiagnosed, leading to chronic symptoms and high costs.
objectiveTo evaluate the diagnostic value of a short dual-task static posturography (sPG) protocol in patients with acute vertigo and dizziness in the neurological emergency department.
methodsWe prospectively assessed 211 patients using sPG. Established patterns (normal, functional, cerebellar, sensory ataxic) were rated on a 5-point scale by two blinded experts. Interrater agreement and non-parametric analyses were performed, and diagnostic classifications were compared with and without sPG.
resultsInterrater agreement was high (Kappa = 0.965). sPG identified functional patterns in 29.3% of previously unclear vertigo/dizziness cases, leading to a highly significant increase in the diagnosis of functional dizziness (p < 0.001). Functional patterns were also frequently observed in organic diagnoses, particularly in episodic vestibular disorders. Furthermore, by detecting cerebellar patterns, sPG identified 20% more cases of central vestibular disorders (from 45 to 54 cases).
conclusionsPG offers a rapid, cost-effective tool to identify functional dizziness in the emergency setting, complementing standard clinical assessment. It facilitates early recognition of functional dizziness and may reduce underdiagnosis and prolonged symptom chronification.
