Hemiballismus as the Sole Manifestation of Acute Thalamic Hemorrhagic Stroke: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Post-stroke movement disorders are uncommon, with hyperkinetic types occurring in less than 1% of cases. Hemiballism-hemichorea is the most frequent post-stroke hyperkinetic movement disorder and is typically associated with lesions in subcortical structures. We report a case of a 68-year-old man with hypertension, diabetes, and prior ischemic stroke who developed right-sided hemiballismus within days of a left thalamic hemorrhagic stroke. Brain MRI revealed a hemorrhagic lesion in the left thalamus alongside chronic small vessel ischemic changes and lacunar infarcts. The patient exhibited continuous, high-amplitude involuntary movements that significantly impaired function. Symptomatic treatment with haloperidol, sodium valproate, and clonazepam led to partial improvement, though complete resolution was not achieved during the hospitalization. This case highlights the clinical complexity of post-stroke hemiballismus, the broad neuroanatomical substrates beyond the subthalamic nucleus, and challenges in management, particularly in patients with multiple vascular comorbidities. Given the variability in onset and recovery, close neurological follow-up and individualized therapy are essential. Further research is warranted to better understand the pathophysiology and optimize treatment strategies for post-stroke hyperkinetic movement disorders.
