Cerebellar activation during a motor task in conversion disorder with motor paralysis: A case report and fMRI study.
Article in Neuropsychopharmacology reports, 2018. 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
backgroundMotor conversion disorders are characterized by movement symptoms without a neurological cause. A psychogenic etiology is presumed for these disorders, but little is known about their underlying neural mechanisms. Functional magnetic resonance imaging (fMRI) has been utilized to understand the mechanisms associated with unexplained motor symptoms. Here, we used fMRI to investigate the cerebral response to motor stimulation in a patient with conversion disorder with motor paralysis to determine the underlying neural mechanisms of this disorder.
methodsBrain activation induced by movements of the bilateral ankle joints (repeated plantar flexion and dorsiflexion) was recorded using fMRI in a patient with conversion disorder with unexplained motor paralysis. We acquired 2 types of imaging data: (i) data obtained while motor paralysis remained present and (ii) data obtained after motor paralysis had completely improved. We used a within-subject fMRI block design to compare the patient's brain activities during the motor task and at rest.
resultsCerebral motor areas were significantly activated during the motor task relative to at rest, both when motor paralysis remained present and when paralysis had improved (
conclusionsThe cerebellum is a region that is closely associated with voluntary motion. We suggest that complementary abnormal function in the cerebellum might be associated with the neural basis of conversion disorder with motor paralysis.
