Meaningless movement with dysesthesia induced by another person's touch or passive movement following brain infarction: A case report

Abstract

Here we report the case of a patient showed meaningless movements with dysesthesia following cerebral infarction. Magnetic resonance imaging revealed lesions on the right in the postcentral gyrus, anterior interparietal sulcus, parietal operculum, and posterior part of the insula. The patient showed no motor paralysis but severe sensory disturbance, including superficial and deep sensations. In addition, she experienced meaningless movements of the left upper limb. She disclosed neither diagnostic apraxia nor compulsive use of tools. The touch by another person or passive movements induced dysesthesia in the left hand, followed by meaningless movements. By contrast, she showed no dysesthesia when touching an object with her left hand or when touching her left hand with the right one. In conclusion, passive somatosensory inputs may be associated with the pathogenesis of dysesthesia and subsequent meaningless movements.
