Arm levitation in multiple system atrophy

A 53‐year‐old woman presented with repetitive involuntary elevation of the left upper limb beyond her shoulder joint. Initially, the symptom was suspected to be due to a functional neurological disorder. Based on the clinical and radiological findings, however, we diagnosed arm levitation associated...

description A 53‐year‐old woman presented with repetitive involuntary elevation of the left upper limb beyond her shoulder joint. Initially, the symptom was suspected to be due to a functional neurological disorder. Based on the clinical and radiological findings, however, we diagnosed arm levitation associated with multiple system atrophy. The mechanism of her arm levitation was suggested to be a disturbance of the right frontal cortex with resultant impairment of the inhibitory mechanisms of the primary motor cortex.
